Would you tell us exactly what did you have to do/swap, etc?

Chieh

 

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.

True...
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

 

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

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

 

was their a significant increase in power?. do you think it was worth all the work? and after the transplant do u wish u would of went with the 2.0 turbo?

 

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...

i have to replace my crossmember (the one that has the rear engine mount on it)...

i was wondering if it is the same piece from a 1.8L and a 2.0l, cause then ill buy a cheap 1.8 and steal the piece
...


thanks for your help

 

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.. oh wait then i get to put it back together...

 

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

 

Another question...is there anything i can use from the 1.8 for the 2.0T..things like the power steering pump or radiator just things of that nature...please lemme know!

Your 1.8 has power steering Oh well, the car is so light, I don't even notice that I don't have it until im in a parking lot. Radiators are the same for both engines, mines been replaced.

 

Everything like power steering and radiator and that stuff is the same..there's really nothing i c an think of that you have to change other than the obvious, wire harness and engine

 

1.8 to 2.0 n/t swap

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

 

1.8 to 2.0 conversion

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~

 

Yes your gonna need the 2.0L exhaust, and no there will be no problems with the new weight, your oil pan will have a safe home..

 

when you said ecu did you mean the ecm? or is it another a diff part?

 

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... its a 92 talon tsi into a 94 gs

 

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.

 

that makes my life so much easier i couldnt be more happy ...i wish someone wouldve told me that before i got nearly everything out

 

I have a 1.8l auto tranny....if I put in a 2.0, will this pose any problems? Also, how much did all this cost you? Do you think you can list out the parts that you had to change, and what you would do differently if you could do it all again? Thanks
