Don't be afraid of it, it wont bite.

 

Forged internals with high compression, nos.
Dont think you wont have to tune, get a standalone. Just cause you dont have a turbo doesnt mean you dont have to do it right.
Its the same formula on any n/a engine 4 cyl.

 

Your car wont being scareing anyone if it doesn't have a kit and your building it as anb/a build.....but then again I guess it wouldn't be n/a with that nitrous. Go turbo.

 

You see i dont want to go turbo. I do love turbo's, but n/a cars can be just as powerful and sneaky. If you dont say you dont have a turbo they will automatically think your slower than another turboed car in a race which isnt true. You see i have a nice GS w/ tag, title and tax all paid for. I dont feel like doing a trade on it for a turbo eclipse, and im not throwing away 3K on a turbo 4g64 engine. NOw if i can build this engine up first i might turbo it later. We all know not to turbo a small engine w/ out upgrading the engines first. If you dont that's when sh!t goes wrong.

 

Bolt on mods wont net you much then with an b/a build of a 420a alot of your power will come from the port work on your head. Just slap some higher compression pistons in there and spray the house down. They wont see whats coming.

 

It also depends what motor your speaking of...the 4G64 is the non-turbo, 2.4 liter, SOHC motor that comes in the naturally aspirated Spyder's. All other non-turbo 2nd gen's come with the 2.0 liter DOHC Chrysler 420A motor. If you have an Eclipse Spyder and are speaking of the 4G64, try the the 4G64 sub-forum on here.

 

keep it n/a like you said right.....then throw on a 1G head on the 4G64 then get some forged pistons or high compression 11:1 and the build it up from the intake manifold to the 4-1 headers........huge waste of money...just get a turbo kit alot cheaper...:banana:

 

YOU can not make the same kind of power n/a that you can with a turbo, just saying that proves that you are not very knoledgable about the situiation. Forced induction adds displacement to a motor, higher compression only adds cylinder pressure. There is no way to make good power from a n/a 4 cylinder. By the way it doesn't cost 3 grand to boost a 2.4 you can do it for less than a thousand, and it is going to be cheaper than you putting high compression forged pistons in your 2.4.

 

If you want easy/cheap, just nos the shit out of it.
Give it a 100 shot, dont even think about anymore than that. As far as a 420a goes, I dont think they like the high of laughing gas.

Your definitly a nos type of car owner.

I have a story with nos, though I;ve never used it on my cars.
I helped my friend setup a venom dry nos kit that came with a harness for the injectors to automatically compensate for fuel. Thats nice and all, but it was on his geo storm. It was just a 50 shot-I think.
Jesus fuck that thing pulled. Well, atleast in comparison to what it was. Still got our asses handed to us by swapped civics. And we're talking normal swaps, no gsr or type r shit. We ran out of nitrous that night, havent ran it since. I'm not sure why I'm telling you this, but I guess I'm just trying to say that you can't polish a turd, you know? Any turbo t/e/l is going to slaughter your ass. Even if you have nos. I know this from first hand personal experience. Swaped hondahs, shit, just a 92si hatch will kick your lily ass until higher speeds. Thats embarrasing, trust me. I had a 92 si hatch with the stock motor and we werent afraid of any n/a talon with nos while downtown.

If i dont go N/A i will turbo my ride. Im not really building a pro race car lol, just want some extra bang under the hood. I might go turbo though not sure.

You dont want to slap a turbo on an engine that was not built stock for a turbo lets say like the 420a compared to the 4g63 w/ out proper building, due to killing the engine and it's internals. At faster compressions (N/A or turbo) you would want to upgrade: rods, a head job, maybe forged pistons, if your running alot of horses to a stock modded turbo engine. If you dont do this you can shoot out a rod, crack a piston, several things can happen. So if you slap a turbo on a 420a w/ out any mods you will gain a good amount of gains, but you will also be killing your stock engine. I want to build on my 420a then put on a turbo or even swap it out for a 4g63. Which one will be cheaper you think. There are several different ways to make a car go fast, im looking for the best way on saving some money.

 

Go the road less traveled. It's alot more frustrating and there'll be no support from others and shit will break that no one understands. I built a decently powerful 1.8L and while it's a pretty good car and all, it does break some now, and it'd been easier to keep it stock and find a 4G63T car and mod that. Oh well, I spent about 1500 bucks building up my set-up and it's working pretty good. I could have spent that money modding a 4G63T and would probably be in the low 13's or high 12's. Instead I'm high 14's and driving it to work everyday. I don't believe in turbo conversions that last. I do believe in using the right tool for the job now and by that, I mean go out and find one turbo'd from the factory and mod that.

 

I sold my 96 rs and bought TWO 1g turbo awd's.

If you want turbo without spending the extra dough, just get a 1st gen. But a n/a engine will never at any point have more power for the money as far as any eclipse engine goes. These arent v8's. Theres just not much room for improvement. At 100% VE you can only move 2 litres of air in a N/A eclipse car. You cant get past that(most the time). The only thing left to do is raise cylinder pressures. That requires an engine stronger that a comparable Horse power turbo'd car. Not to mention you wont have the powerband of a turbo car. I think your trying to keep it simple, which is what you should do, but a n/a build isnt as simple as you would think. Its just as complex as a turbo build at higher comparable powers.

 

If you just want a little more power then turbo it. The power gain you would get turboing it would probably cost atleast 2 times as much all motor.

 

You see i dont want to go turbo. I do love turbo's, but n/a cars can be just as powerful and sneaky. If you dont say you dont have a turbo they will automatically think your slower than another turboed car in a race which isnt true. You see i have a nice GS w/ tag, title and tax all paid for.

What you're saying would be logical, right? Build the engine first for n/a, then go turbo it later? In reality if you went n/a you would want higher compression pistons to make more power, but then if you wanted to turbo it then it would be a rolling grenade waiting to explode. Turbo cars are more suited to lower compression, and if you slapped lower compression pistons into your engine but didn't turbo it, you would actually make your car slower.

Bolt on your n/a if that's what you want, turbo it if that's what you want.

 

Im just going to build up the internals and what not so the engine can handle the turbo and extra horses.

It would be the better idea to put together and bolt on the turbo system at the same time you build the internals. Make sure you know exactly what you're doing though...don't blow anything up.

 

So... what engine are we talking about the title says 2.4 but halfway through we switched to 420a. So which one are we talking about?

 

I tell ya what. I'm gonna break this down for ya, just because I feel like you'd learn more from this than you would if you just watched this stupid thread.

You dont want to slap a turbo on an engine that was not built stock for a turbo lets say like the 420a compared to the 4g63 w/ out proper building, due to killing the engine and it's internals.

No, you want to turbo everything possible. Just make sure you prep the engine first. Like you started to cover below.

At faster compressions (N/A or turbo) you would want to upgrade: rods, a head job, maybe forged pistons, if your running alot of horses to a stock modded turbo engine. If you dont do this you can shoot out a rod, crack a piston, several things can happen.

The things you listed are not based off of the amount of power you put down. They're based of the amount of work you put into tuning it. Obviously the 4g63t can withstand more abuse than that of a non-turbo 420a or 4g63, but again, tuning is what will make or break your engine.

So if you slap a turbo on a 420a w/ out any mods you will gain a good amount of gains, but you will also be killing your stock engine. I want to build on my 420a then put on a turbo or even swap it out for a 4g63.

You'll gain a good amount of gains? WTF? Go to grammar school then post again. And no, slapping a turbo on anything will not net you anything. It's all about tuning and support, my friend. Oh, and go research some more, because you CAN NOT swap a 4g63 into a 420a t/e/l. Well, I take that back,. I suppose you could, but it'd take more money than it's worth.

Which one will be cheaper you think. There are several different ways to make a car go fast, im looking for the best way on saving some money.

Um, pick two: Cheap, Fast, Reliable.

 

Their was a guy a while back who did an N/A build with the 4g64. He had everything- upgraded internals, head work, header, even a magnus intake manifold. He, uh, described the ride home after the work was done as the most disappointing 10 minutes of his life.

 

^^^ lol. If i was disappointed after all that work was done i would have been pissed.

Kronus. You see that's the thing, i dont want to have to tune my engine as much as your saying. I want to build the engine right and safe were i wouldnt have to get my engine tuned every month. That's some extra cash if you dont know how to tune it yourself. I know tuning is mandatory but if you do the job right, you dont need it done all the time.

You see thats his problem. He built the engine up that much but nothing to feed the upgrades. That's when you turbo. Then you have all that extra air and power feeding the sh!t he just upgraded. It's like this, the more air you have coming into the engine (turbo, s/c) and the more air you have flowing out (catback 3" piping) the more gains you will get. If he had nothing feeding the engine w/ a lil 4banger he wouldnt enjoy the gains.

Well if you don't want to tune it, then be prepared for trouble. It's not about tuning every month, it's about tuning it the right way the first time, and making minor adjustments for weather, fuel, etc. And you just contradicted yourself.

"I know tuning is mandatory."
-Good, you are correct.

"But if you do the job right, you don't need it done all the time."
Incorrect. You could have the beefiest setup in the world, but if you let your tuning go to heck, it's not gonna last. Sure it'll take more abuse than stock, but not that much more. And tuning is what makes power too. So slapping a turbo on and throwing in a new bottom end is not gonna make you the fastest sh*t around. Sorry bud, do some more research.

 

Spray the shit out of it, call it a night, go home and eat chicken nuggets.

 

NO spray unless i build the engine up first. I already expressed that i will build up the engine then look for a 420a turbo setup. Thankx for the feedback.
