where can i find a GST eingin swap to replace my stock engine? i need some websites if anyone can help.thanx

 

www.japandomesticmotor.com has engines from Japan with low miles on them. They have 4G63 Turbo engines.

 

try some local junkyards too, you may be able to find a wrecked one you could get one out of for cheap.

 

would i be able to take the 4G63T engine from the 90-94 eclipse and srop it into my car or wouldi have to get it from the 95-99 model year?

 

You *can* drop it in....but realize the procedure is long and costly. Either the 1g or 2g engine will fit, but you'll need to change out transmission and axles also.

 

i thought the gs-t used the same tranny as the gs? at least i was told it did!

It's kind of tricky, the 1g's had almost the same FWD transmission. The 2g's had different engines between the RS/GS and GST's, or basically the non-turbo and turbo cars. The non-turbo cars used a chrysler designed transmission, which BTW is *very* durable, in stock trim it can withstand 450hp. The 4g63's use a Mitsubishi made transmission. Neither transmissions are related in anyway except for the fact that they're both found in DSMs. They don't share any internal or external parts(save for a few hoses i believe). Also, the 4g63 block will not mate up to the 420a transmission. They say you can fab an adapter kit to work, but that's much too expensive, and requires a bit of trial and error. If you are planning on doing the swap though, to my knowledge only 2 people have done it so far. However, they had complete donor cars, since so much needs to be changed. Almost nothing engine related is shared between the turbo and non-turbo 2g cars.

 

I am not EVER one to say do not do something. Hell, I am in the middle of a FWD-to-AWD conversion as we type.


This is one exception though. Trying to put a 4G63T engine in a 420a bay is going to require ALOT more than you should pay. It can be done, but at more cost than a new car. The entire engine bay needs to be transplanted basically.
