Swap it for the 4g63. Unless you just want a little boost. Do your math if you stick with the gs engine. You could bolt on the charger and then do the swap after you break something.;-)

If u really like the 420a u can jus turbo it...or take it apart drop compression etc....and try to break the 661 whp record ...but no u cant swap it the 4g63 wont fit in the same mounting places

Well if your asking about the 1997 Mitsubishi Eclipse GS, w/o turbo it's 140. GS Eclipses don't come stock with turbo so either your looking for a GS-T or GS-X, or you have put your own turbo and that would be specific to your turbo set up.

The Mitsubishi GS does not come with turbo...... ^^^^^^ Idiot... The Eclipse GS did come turbo, surprisingly it was called the Eclipse GS-T, I wonder what the T stands for. Now, with that out of the way, the firing order is 1-3-4-2..

No. The gs is the base eclipse spyder model.

look at the engine, is there a snail shell looking thing attached to the front of the engine...if so then u got one. ------ If your Eclipse is a GS or RS it did not come from the factory with a turbo. the engine should be on the passenger side of the car. That engine is a 420a. If you have an Eclipse GSX or GS-T then you have a turbo charged engine. the engine will be on the drivers side of the car. this is the 4g63 engine. it is possible to have a 420a with a turbo, but someone will have had to put it on themselves, and you would probably know that when you bought it.


A Spyder GS is a non turbo car. A GS-T on the other hand is a turbo car. Hope this helps

The turbo is a T-25 .... comes on the gs-t and gsx

Yes.. turbo systems are universal unless your car electric and doesn't have an intake or exhaust system.. however do your research before bolting on turbo system on a gs because if you have the 95 - 99 models the engine is not the best engine to boost.. it is very weak..

No the engine in the 98 mitsubishi eclipse spyder gs is a mitsubishi 4g64 while the engine in the 96 rs is a chrysler 420a engine.

there is no gt turbo. there was only the gs turbo and the gsx which was turboed, the gt didn't come til the 3rd generation eclipse which was in 2000 but 2000+ are all non-turboed.

the normal boost is 5-12 psi. the normal vac is about 18-20 psi

The engine, accessories, transmission, computer, exhaust, etc - it would be cheaper to simply sell the non turbo and buy a turbo model. Alternatively, Hahn Racecraft makes a turbo kit specifically targeted to the 420A engine in the Eclipse RS/GS and Talon ES/ESi for prices of approximately $3k, and is offered in several customized layouts.

RS is the base model with manual windows, manual locks, no sunroof (mostly), no foglights, no spoiler, no rear wiper, no cruise control, etc. Gs is the non-turbo upper model with power everything, spoiler, sunroof, etc. GST is same as GS with turbo and GSX is same as GS with turbo and all wheel drive.

Yes, The cars are exactly the same body wise.

On an Eclipse GS.........the "GS" stands for Grand Sport

Yes, you can, but there is a chance that you will need to change transmission and everything what is going inside the engine. The problem is that Mitsubishi engine parts from different engines are not compatible (it can be turbo Japanese engine, or non-turbo crysler engine and so on).

It varies between cars. For the gs-t it'll be around 9-12 psi.

It should be the same thing the only thing that really matters is if it an automatic or a manual. They bolth have to be the same.
