Ok people..I know there's alot of questions to be answered about the 1.8 to 2.0 swap. I have succesfully completed the swap and I'm willing to answer any questions out there about this job. I didn't have any help doing my swap and i know how much it sucks. So if anyone has any questions just let me know. there's alot of bullshit running around about..trannys and fuel pumps and all kinds of shit that you don't need to do.

The 90 harness is very different to the one on the 91-94 engines (2.0).

Maybe you could outline some of the mayor or most significant modifications needed...;)

hey what about drivetrain? or did you just use the 1.8 tranny

93talon2.0

10-18-2002, 08:05 PM

the 1.8 and 2.0 tranny's are indenticall..the only change is with the turbo model because the flywheel is bigger on the turbo model. but we don't need to get into that.. were just talking 1.8 to 2.0 n/t. the electrical on a 1990 2.0 is almost all different inside the car. the whole dash needs to be ripped out and replace all the harness's behind the dash. for that peticular switch. i image if u got the harness from the same year car u could do it with much ease. to change the harness the passener side of the dash needs to be pulled back a bit so you can take the heater blower motor out and behind that under the carpet the harness runs to the ecu. any other questions?

so whats involved in putting the same year engine in the 1.8? im not clear as to weather i would need to have a whole new harness or i could hack in some wires.
thanks

93talon2.0

10-19-2002, 11:37 AM

your gonna need the whole harness from the engine bay that runs through the firewall to the ecu. if it's the same year everything should just plug in..just make you have a 2.0 ecu to plug in
good luck man.if u have anymore questions let me know..also when u do the swap the tach won't work because you have to splice in the wire off the engine to the tach and i dont know how to do that :( i havent figured it out yet because i blew my tranny and pulled it for the winter

93talon2.0

10-27-2002, 08:34 PM

there was definitlyu a big differnece in power. it was well worth it..right now im in the process of turboing my n/t turbo is definitly ALOT BETTER but if u can only get a 2.0 n/t it's well worth the trouble and turboing it is not that big of a job either. so i went fro ma 1.8 to 2.0 to 2.0 turbo :)

Hey what's up...im swapping the 1.8 out of my 94 GS and putting in a 2.0 T from a 92 Tsi...how do the mounts line up(ive heard so many different things)...if they dont what modifications am i gonna have to do...also how the HELL do i get the engine harness out...its in the firewall and i almost have the dash pulled is there a clip of some sort? I cant wait to do the same thing when im taking the 1.8 out not for another day or so though..:rolleyes: oh wait then i get to put it back together...

93talon2.0

10-05-2003, 09:54 PM

Hey,
Everything mounts up just fine. It will fall right into place like it was meant to be there except.. your hood. Does your hood have a bubble for the timing belt cover? If not u might need to get a new hood. The harness runs through the firewall right by where your passengers feet would be. It's been a while since I've done the swap now but if i remember right ..the harness goes through the firewall with a plastic clip..type..thingy...it's a cirlcle so the water and shit doesn't get into the car..you can take it out from the inside of the car..under the carpet..good luck.. let me know if u have any other questions

I spun a bearing in my 1.8 so im in the market for a new engine rather than a new car. I can come up with an entire front clip of a running GS 2.0 for a really good price but Im in dire need of EXACT and FACTUAL truths that will dispell any confusion i have about the swap. The car is a 92 GS 1.8L SOHC being replaced with a 92 GS 2.0 n/t. So this is what i need to know:

-Does the 1.8 Tranny bolt up to the 4G63 N/T engine if its out of the same year?

-Do any of the Radiator lines need to be moved or changed?

-How much will the car drop in ground clearance from the heavier 4G63?

-Are ALL the engine mounts in the right place for the 2.0?(meaning is it completely plug and play? or will i need to do some fabricating, if so on what mounts?)

Any info that you can give would be GREATLY appreciated. And please, dont post unless you are 110% positive the statement you make is true. Please no bench mechanics. Thanks all ~peace

The answers are : Yes the tranny bolts up no problem..the only place that you would need a new tranny is a turbo engine..but if your going n/t to n/t then your fine.

No radiator lines need to be moved or anything.

Everything is bolt in and plug in the new harness, no modifications nessissary. good luck

The 1.8 exhaust needs to be replaced too with the 2.0L too right? Also, about the weight differences, is the 2.0L that much heavier? My car is slightly dropped (1 - 1 1/2ins) will i have oil pan clearance issues? Thnx, peace~

93talon2.0

10-29-2003, 04:34 PM

I never changed my exaust system it will bolt right up. I bevlieve both n/t engines have the same diameter exaust pipes, when you go to turbo it's a lot different though. The ecu is the engine control unit. ECM,PCM Computer, brain, etc. are all different names people use for it. It is located behind your radio. It's just a square Metal Box with 3 big plugs going into the bottom.

Im happy to say the swap is coming slowly but surely..one question... i had an idea that all i need to change is the ecu harness from the 2.0T into my 1.8 and not the whole interior harness...i thought about it and i wouldnt see why not....please tell me im right...:confused: its a 92 talon tsi into a 94 gs

11-20-2003, 11:52 PM

You would be fine to switch just the engine harness because your going from a 92-94 wiring. but the 1990 model had different wiring than my 93. so i had to swap out everything.

93talon2.0

To be honest with you I don't know anything about the automatic tranny. I would assume it would fit ok, as long as it's not a turbo engine. List of parts, : Engine, Engine Harness, ECU, patience and some time. I acutally paid someone to switch out the harnesses for me. That's what I would do different. I turns out it was really easy to pull the dash off. Just take your time, everything fits and ther'es no real modification to be done. If you have any questions you want to ask me, my aol name is suprpmp77 and i can't explain. Good luck

Yea you can use your sister inlaws 2.0 along with your 1.8 tranny as long as it's not a turbo 2.0 your putting in. And you'll have to switch out the engine harness. good luck

I have a 92 1.8 and my mechanic has an 4g63 n/t engine that he pulled out of a 92-94 eclipse. The guy never came back to get the engine and it just had a knock. My mechanic has left it outside for 3 months and wants to get rid of it so I will get it pretty much for free. Anyways, is the wiring harness in the interior the same for all 1gb eclipses? Or does it change every year? Will the 1.8 MASS and 02 sensor work on the 2.0?
-Thanks

Whiteonyx86

02-05-2004, 02:12 PM

I believe they will be the same, all i have to change on my harness is the ecu/engine harness...along with the ECU, which should be simple. I didnt have to mess with the interior harness at all...someone please correct me if im wrong.

93talon2.0

02-05-2004, 11:36 PM

The 91 and 90 dsm's have the same harness, and the 92-94 dsm harnesses are the same. To interchange them you have to mess with the interior harness. No the 02 sensor and maf sensor will not work. you wil have to get those parts from the same year 2.0 engine.

Yes you have to have the 2.0 Ecu for whatever engine you have (turbo or NT). If you look I did the first original swap back in 2001 and I have somewhat of a write up on it in this forum. I have swapped out two 1.8L to 2.0 turbos ;)

Hi I'm new here and i really am considering swapping out the 1.8 on my 94 eclipse to a 2.0 n/a. All i would need to do is swap the engine and ecu, correct? Also, where would be a good place to get a hold of a good 2.0. Thanks

Man if you will search all this is documented. To answer your question no you will need more than that. You will need the wire harness as well. Also the intake manifold and MAS is needed as well as the tranny. The 1.8L tranny will bolt up but good luck with it as the NT tranny has enough hp increase to run that 1.8 tranny to death. In short you will need almost everything to swap the stuff over. Way easier and cheaper to just buy another car. Speaking from experience here buddy ;)

I have recently overheaded my 1.8 on my 1991 gs and warped the head if not cracked it. It has 180,000 miles on it so i dont feel like sinking hundreds of dollars into it.

A mechanic that i went to found me a 2.0 n/t for $1000, brand new-0 miles (not rebuilt). He said he would swap it for another $500.

What i need to know is the basic parts needed for the swap- engine- same year (91'), ecu(2.0), engine harness(2.0), 2.0 header, 2.0 02 sensor. Would that be it? i need to gather these parts ASAP because its getting done in the next couple of days.

Also the engine harness(2.0) is a plug and play with the ecu(2.0) once installed with the swap? what about the tach not working, it wont after the swap? MAF do i need the 2.0 one they look the same 1.8/2.0? Any info will help thank you.

Whiteonyx86

04-27-2005, 07:02 PM

I have a extra 1.8 head with everything and a complete block, if you needed anything i could sale it to ya no problem. First off if you wanted to swap the 2.0 in, you would need the engine harness, which runs from the ecu up the back wall into the engine bay, the interior harness can stay, the ecu harness i think has a couple plugs that attacth to the interior harness, you would need the new ecu, maf, and possibly the gauge cluster harness. Everything is plug and play.

good to know, thanks for the clairity on that, honestly i would rather spend the money on the new engine because i have completly restored the body and would like to keep this car for awhile plus this gives me something to mod later on down the road :D , again thanks for the help.

04-28-2005, 08:46 AM

You will need the coil pack and the transistor for the same year car was well. If it is a 90 car then use a 90 coil pack and transistor. 91-94 are all the same. Need the same year CAS as well.

Let me think, engine/tranny, harnesses, manifolds, coil pack, transistor, CAS.

If you are getting a new engine I am assuming a long block. You may need a thermostat housing (or maybe only the turbo one is different to feed the turbo). If the engine isn't assembled have him take the balance shafts out so that the bs belt won't snap and mess up the timing components and your head/pistons. You will need the gauge cluster out of the same year car from a NT 2.0 as the igniton is driven differently (ie coil pack/transistor).

eastcoasttuner

04-28-2005, 08:49 AM

The car is a 91 and i believe the new engine is too, so i wont have to worry about the 1990 problem. As far as the gauge cluster its all plug and play right? thank you for the help.

05-11-2005, 02:12 PM

I REALLY NEED SOME HELP HERE ASAP! :confused:

like i said before my mechanic found me a new engine for my car. Not really the case exactly! it is a new engine from a Hyundia thats a DOHC. I looked at the engine and it almost looks like the 4G63 2.0. But the numbers on the block read 1.8L so its a 1.8L DOHC? Will it work for this swap? its ready to be dropped in, im just waiting for the parts: so far I have an obx header for the 2.0 coming, also i have the following used parts coming,

(91-94 2.0) used parts: engine harness,ecu,power transistor, maf, cam angle sensor.

I NEED TO KNOW IF THIS HYUNDIA ENGINE IS ABLE TO BE SWAPPED? DOES ANYONE KNOW? ALL THE MOUNTS ARE THE SAME ONLY REAL DIFFERENCE IS THE APPEARENCE OF THE INTAKE MANIFOLD. :(

If i cant swap that engine the parts place has other used engine there selling, (ALL 4G63 2.0 n/t) one has only 48,000 miles and its a 1993, so i asked my Mech, to see about just pulling that one, he called and they told him it wont fit!?!? they said it only works between the 93-94 dsm's? is that true? i though 91-94 2.0 n/t engines were all able to swap in place of the 1.8L? :confused:

IF ANYONES KNOW WHAT TO DO PLEASE HELP, MY CAR ALREADY HAS THE ENGINE PULLED AND ITS JUST SITTING THERE...AND IT NEEDS TO BE DONE SOON, SHOULD I JUST HAVE THEM PULL THE 1993 2.0 FOR ME, IT SHOULD FIT RIGHT.

so now your running a different engine? im confused...first off any engine from a 91-94 will fit in your car whether it be a 4g63, 4g63T or another 1.8...all engine mounts line up perfect no problem. And if you have to ask a question about a hyundia engine working for the swap and it hasnt been answered clearly yet, then i wouldnt put that engine in. Tell them you want the 1993 engine, if you have any problems with it there are more than enough people on the board to help you with it. Stay away from the hyundia engine.

That is where you are wrong. The motor mounts for the AWD is different than the one on the FWD. The AWD has a subframe brace that runs horizontally on the DSM whereas the FWD has one running vertically. They almost do fit but they are off by an inch. Fix???? Drill another bolt hole about one inch in the motor mount bracket for both the front and rear mounts. Side mount bolt right up.

It is the FWD vs AWD. All the FWD engines (4g63 n/t and t as well as the 4g37) will bolt in. The AWD will only work if you swap over the mounting brackets. Don't be fooled.....it is only the angle and length of the bracket that is different. They all bolt to the engine and tranny in the same places. :cool:

Still a little confused about the wiring harness. Same year, 94 to 94 Mine was a 1.8 the new one is 2.0 n/t. Got the computer out but every wire in the car seems to be wrapped in the bundle through the firewall, do i need to pull the whole mess, a small bundle or nothing at all? I noticed a (cam sensor?) on the new engine and I can't find a matching plug. Everything else <<seems>> to match up...

QuickOne

05-18-2005, 07:23 AM

Yes you need to pull that entire bundle through the firewall. It is a major pain but....anyways any other wiring that may clip off that main bundle and run inside the car can be disconnected at the clip somewhere nearby. The cam sensor should plug in off of the main harness.

05-25-2005, 11:41 PM

Can someone who's done this elaborate a little for me. If I wanted to run a 2.0 engine harness and ECM of the same model year, do I need the ENTIRE harness, including the fuse box and dash wiring, or will the 1.8 dash wiring work with the 2.0 guage cluster? I'm hoping all I need is the engine harness.

I'm out of room for fuel on my stock ECM and I've got an extra 2.0 eprom sitting around so I've been playing with the idea of upgrading my ignition to the 2.0 ignition system, adapting the 4G63 throttle body and ISC, and using the rest of the 2.0's sensors, and just programming in the optimum ignition and fuel maps for my 4G37.

Anyone who's done the swap know if there's a difference in the dash wiring?

Whiteonyx86

05-25-2005, 11:52 PM

to run the 2.0NT all you need is the 2.0 NT harness it runs from the engine bay through the passenger firewall and into the ecu, there are to other connectors that connect right by the passenger door, 2 i think. the rest go to the ecu. The only other possible harness you might need (turbo only) would be the gauge cluster if you wanted to run the factory boost gauge. You do not need the fuse box or the dash wiring so do not take any of that out. Leave the fuse box and everything intact. ECU harness only

If you have the 2.0 harness then the 2.0 gauge cluster will work. No the 1.8 guage cluster will not work on the 2.0 harness. The 2.0 has some thingy on it that drives the rpms signal and the 1.8 was mechanical off the tranny I think. I can't remember.....I don't own a POS DSM anymore. I have improved to Subaru WRX ;)

Whiteonyx86

06-08-2005, 09:37 AM

the 1.8 gauge cluster will work with the 2.0 harness, the only thing is you have to tap the tach wire from the 1.8 gauge cluster into the rpm wire on the ecu.

Back from buisness trip ... got the 2.0 in. Had to get a new clutch, transmission fit ... but the Mitsubishi service manual lists a different trans. Does anyone know how long the stock 1.8l transmission will survive the additional power? The transmission is in great shape, but the one I pulled out of the parts car was toast and when i opened the case (curiosity kills, kids) there were all kinds of broken gear teeth and oil that looked more like the stuff that i clean off of the driveway than any sort of lubricant. Oh yeah and the springs were missing from the old clutch i suppose they got chewed up bcos i never did find them.

anyhow do i need to start shopping for a tranny? wish me luck with the wiring!

Not to knock the swap, but this seems worth mentioning (Impressive that you've done it and congradulations on making it work).

The 1.8 tranny is different than the 2.0 n/t trannies, which is different than the turbo trannies.
1.8 = F5M22-1
2.0 = F5M22-2
2.0t= F5M33
AWD= W5M33

I wish I could tell you more about the numbers, but it seems pretty clear that the 22 designation is for n/t cars, and the 33 for turbo cars. I know that the 2.0 n/t is supposed to be weaker than the turbo because turbo people seem to break them. Yes they will bolt up because it's less expensive for mitsu to make one bellhousing, but I'm not so sure they put stronger (more expensive) parts into a tranny that only needs to handle 92hp. It might work for some time, but a turbo motor is already twice that much hp. Also, I'm not sure that the 240 pound weight savings can really justify the trouble (How much more does the 2.0 motor and necessary parts weigh? I'd guess close to that.), and really you'd save a lot of time, money, and effort just buying a turbo car with a bad motor. But you guys are dedicated.

I lucked into a wrecked laser of the same year as my eclipse (94) just when i was about to unload the eclipse (broken piston arm) but the laser had the 2.0 motor and only 75k miles. eclipse had a 1.8 that ran for 250k. and here i thought it would be fun to get my eclipse back on the road ... sigh ... Daily Scheduled Maintenance indeed

Engine
Clutch(replaced)
Computer (ECM & the little box under there with it?)
Pully from the air conditioning compressor (didn't have to drain the system)
Gague cluster
Exhaust manifold
Wiring harness from dash to motor, didn't need to rewire the fuses or relays
Hanger bracket for power steering pump

Now I sit here amid the crackling of my knuckles thinking ... upgrades?...

Alright. I've stumbled across a 6-bolt 2.0. It's gonna need a rebuild, but that's the least of my worries. I found the engine as a core someone had turned in.

This means that I have no idea what year it was, it has no harness, and I have no idea if it came from an auto or a manual.

Some questions for you guys and gals.
1. Does anybody have any info on making an entirely new engine harness?
2. Does it matter if the ECU is going from an auto to a manual? Or does it need to be from manual to manual and auto to auto?
3. Does it matter if the engine came from an auto if it's going into a manual?

Thanks in advance!
-Kevin-

1. making a new engine harness can be done obviously but clearly not worth the time and effort unless it is an all out drag car.
2. the ecu needs to match the transmission type simple as that.
3.it does matter if the engine came from an auto depending on if you get a long block or short block. The auto 4g63T has smaller cams(depending on year) and a smaller turbo the 5 speed 4g63t comes with larger cams larger injectors and a larger turbo...the 4g63 is all the same in its non turbo form.
Really all that matters though is which tranny you wanna go with since all will fit the block.

Also my 1.8 tranny fit a 2.0NT which means itll also fit a turbo car, the problem with that is the flywheel and clutch would need to match with the tranny being used...i know that the 1.8 Tranny has shorter gearing and thats about it...obviously though the 1.8 tranny would not be of any use on an awd car.

For wiring you simply need the ecu harness out of a turbo car...everything else is plug and play. (91-94) harnesses are all the same the 1990 harness is different. There are only maybe 3 connections on the interior of the car that you need to hook up with the ecu harness other than the ecu itself

okay, so heres where i am not clear...If I was swapping a 1.8 with a 5 speed to a 4g63T what tranny would I need? I would need a 2.0T tranny? Or could I use mine? If My tranny bolts up to a non turbo than why wouldn't it work for the turbo motor? Because it's too much power for it??? Prob a dumb Question

Whiteonyx86

10-30-2005, 11:27 PM

you can use any tranny...the turbo tranny is built stronger and has taller gears...a 1.8 has much shorter gearing...but yes they all will work just make sure you have the rigght clutch flywheel combination for the transmission your using

QuickOne

10-31-2005, 07:19 AM

You will break that 1.8 tranny soon as you launch it. Trust me. The 2.0 NT tranny works just fine. It is just as strong as the turbo tranny just the gears are a little shorter. It's a trade off. People argue that the turbo tranny is stronger but have yet to prove it. I ran a 13.1 spinning like mad on a NT tranny just to give you an idea.

fatalshock

10-31-2005, 07:28 AM

well can the AWD tranny be used for a FWD application? I mean could you just not connect the rear output and use it as a fwd tranny? Reason I ask I s that I may sell the engine I have now for one of those imported jdm cyclone swaps with everything needed for the swap found on ebay. And all that is offered on those is the AWD tranny. Better yet could my car be fitted with AWD???

QuickOne

10-31-2005, 08:18 AM

Car can not be made into AWD as there is no where to run the driveshaft. As for the AWD tranny, there is a way to turn it into a FWD tranny but I dunno how. TRE does it though so you may want to contact them. You cannot simply leave the rear disconnected as then the tranny just would not work and you are asking for more problems with something spinning back there.

fatalshock

11-01-2005, 05:05 PM

damn!!! TRE will modify my new AWD tranny to FWD with a higher 5th gear for top speed for only 300$!!! These guys are fuking great!!! only thing I keep seeing that I don't understand is that some people are selling 4g63t setups listed as only fitting 95-99 Why would they be different aside from wire harness' and ECU? can someone clarify??

WhiteFwdsm

11-01-2005, 07:31 PM

6 bolt? 7 bolt? What does this mean?

6 bolts 4g63 came in 90-92 until May of 92... the rest came in 7 bolt 92 1/2-94.

Best bet is to get a 6 bolt. I've owned 2 DSM's with 6 bolts and they are much stronger and tend to last longer then a 7 bolt. The way you can tell is by the oil pan... also by the transmission end of the engine (crank) you will either see 6 holes for bolts or 7 holes for bolts that attach the flywheel to the engine (crank).

it's a long friggin process and I'd be writing pages worth of details...just ask me specific questions there's some electrical work to be done but not too much..plus..if u have an engine already tell me the year engine..u need the wiring harness that goes from the engine tothe ecu depending on the year you may have to change the whole harness in the car. i did because i took a 90 2.0 engine and put it in a 93 car..some things changed over the years..your best bet is to find an engine that came from the same year.

excellent ive been looking for something like this, okay i have the exact same yr engine my 1g is march 94 1.8l and the one i pulled out was exactly same yr same month haha i was lucky as hell, so yeh i was wondering if i could use the same wirng harness just splice or change some pins around the harness and i know the ignition coil stuff but what exactly did you do did you just change the whole harness?wat do you recomend i should do??thanks

Whiteonyx86

06-07-2006, 04:35 PM

in terms of the harness...all you need to change is the ecu harness...which runs from the ecu then out through a hole on the passenger side of the car into the engine bay...also if you change the gauge cluster you will want to change the harness for that as well(allows the boost gauge and ect to work on the turbo gauge cluster)...at the point everything is plug and play, there will be a few connectors if i remember right that wont need to be hooked up, but itll be obvious

after that...the engine bay is all plug and play as well...just make sure you get the corresponding items from the turbo car that the harness will plug into (ie: BCS, MAF)

Does anyone have a vaild reason why I couldn't use an auto ECU if I swapped into a manual car?

Whiteonyx86

06-07-2006, 10:52 PM

well one valid reason i can already see...auto cars have a smaller turbo and smaller injectors...im assuming you probably have a 14b and 450s on your swap...different fuel tables means problems, so unless you have some means of fuel control to correct the ecu seeing 390's when in fact you really have 450s then just go find a MT ecu

A friend of mine is selling me his 94 eclipse real cheap($300).the motor is not running and I will be pulling that out as soon as I get some free time.if I could find the 92-94 4g63 motor and tranny already together with wiring harness..etc would that be a smart move.

dsmbuilder

07-03-2006, 02:58 PM

there is no problem with using the auto ecu, the ecu has nothing to do with injector sizing, there is a resistor pack inline with the injectors to add resistance to the signal to the ecu, You just need the resistor pack for the 450's opposed to the 390's. I have done the swao multiple times, and never had any problem running 450's with an auto ecu.

instead of yanking the axel out it might be better to take a prybar or a nice flat head screwdriver and poppin the axel out from the tranny that way instead of screwing up the axel, cause my axel on my 2.0 was a bitch to get out but i was replaceing it so i didn't really care what happend to it. and as for the 1.8 tranny blowin it won't happen, the 2.0nt and 1.8 trannys are the same tranny, nothings stronger or week between them.

09-06-2006, 10:57 PM

the tranny will not blow...and in order to get the axles out..you pull the wheels slide out the cotter pins on the axle nuts then pop the axle nuts off then take the 2 bolts off of the shock tower...then yank the shit out after you pull it out of the rotor

That's a crazy way to pull out an axle. It would work, though. But, a lot of unecessary labor is required (also, you run the risk, as mentioned, of tearing the boot).

not to reactivate an old topic, but like I have been saying on other threads...I got most of what I need from a canadian jdm importer and got the full harness, AWD tranny ecu, and lots of other shitt. My question is for someone to re-clarify the issue of the front and rear mounts lining up, and specifics as to if new holes just have to be drilled for the existing mounts or if i will need the AWD mounts. I realize the crossmembers are severely different in arrangement, but does the 1.8 crossmember running the length or the car thats dead center of the engine bay interfere w awd tranny clearance?? What firewall mounted issues will be different such as wiring parts,brakelines, fuse boxes, mount bolts (lengthS different?), shifter linkage needs to be changed I think, just touch on the details....or is this as simply barbaric as to just rip one set of crap out and reinstall the new engine/tranny/wire harness,ecu,gauges and stuff??? As for the AWD tranny...I'm buying thVCE kit to eliminate the rearoutput shaft. Any tips here? I'm mostly worried about the mounts.

The donor was my '92 2.0L AT car that was killed off by a truck; thank God for those Prothane mounts for keeping the engine/trans in the car! :cool: I ended up stripping it out totally & will be transferring that engine and transmission. I want to put the 2.0L cluster in as well since its got the 9k redline and has the correct mileage for the engine. Any chance that this will be a problem given that I'll be using the engine harness/ECU and TCU out of the 2.0L car with this cluster?

I just picked up a flywheel that has the 6 bolt holes but it doesn't seat right. Are there different sized flywheels? It seems like it is just off a few mm.

Also the motor I am planning on getting is from a 1993 eclipse the 4G63 would I need to rewire the whole dash or just get the engine wiring harness and the ECU? Could I get both the same harness and ecu out of a junkyard and plug it all in and go. I was told by chrysler that the ECu's have to be programmed to the engine? I would pretty much like to know everything I need to know before I do the swap. thanks.

yes that is correct. you can just get the engine, ENGINE wire harness, and ecu. The ecu HAS to stay with the same year/type engine. i.e. you cannot use a 1991 1.8 sohc ecu on a 1993 2.0 n/t. good luck

Well i got my 4g63 motor, ecu and wiring all ready to go. It came out of a 90 laser and I have a 92 eclipse. The engine is a n/t but I was wondering what I should do to it so that it will safely accept boost. I am rebuilding it as we speak so the motor will be completely fresh. So can I boost it with the stock flywheel and all or do I need to do some modding before I turbo it?

Stock flywheel should be fine, but you're looking at turbo pistons, nice to have turbo cams, stronger clutch, larger injectors. Those are the basics. There's plenty of info around here for turboing an n/t engine.

I'm about to undergo the 2.0 swap, and I'm scared about some wiring issues. The engine came from a 91 laser, pulled it a few days ago. I have the entire harness, the ECU, and the box beside the ECU where the one connector goes ( I think fuel pump relay ). The wiring under the passenger side dash, where the wiring comes in, is a bit different from the 2.0 though, so I'm kind of worried this wont work.

http://img525.imageshack.us/my.php?image=1024071731om4.jpg (image of what the current connector looks like) and the 2.0 connector looks similar to this (http://s151.photobucket.com/albums/s151/dsmcrazy1g/?action=view&current=HPIM1508.jpg) <- someone on the forums photobucket.

finished bolting everything up, and the car runs. I still need to get another downpipe bolt, I have an exhaust leak but she runs like a scalded ape. It wasn't too difficult, now I'm just having issues with my dash wiring since the douche before me tried to swap a 2.0 didn't even have a 2.0 harness or cluster to use hacked everything up. Other then that the power difference is huge, you wont be sorry if you take the time and endure the headaches to swap them.

but you're looking at turbo pistons, nice to have turbo cams, stronger clutch, larger injectors..and a stronger transmission. For a NT (F5M22) transmission will not handle the massive torque of a turbo motor for you'll bust up the gears inside real bad on drop clutch/WOT runs. - why the 4G63T motors had larger flywheels to mate up to the F5M33 transmission - a larger, stronger transmission to handle such power.

I have yet to see anyone break the NT transmission. If anything, I've seen more broken turbo transmissions. I put well over 300 through my NT trans and it was fine when I sold the car.

I am wondering if the 4G37 from the 1G DSM is the same as the 4G37 from the 89 Colt Station Wagon.
I would assume, the 89 Colt SW and the 90 1G DSM would have similar electricals. Assume trans would be similar too.

I have a 1989 4WD Colt Station Wagon.
A 4G63 NT swap into it would be nice. Turbo later on.
