St Jaques des leeds,
I want to get 300hp in my eclipse, and i know that the evo has about that stock. So i want to know if i can put an evo's engine in a 97 eclipse GSX?

#1 use the search. No, it doesn't fit, the engine sits 180* from an Eclipse. If you do have an Evo VIII at your disposal, you could swap in the ECU, injectors, fuel pump, MAS and then buy an exhaust and FMIC for your GSX. The main reason that an Evo makes a stock 300HP and a GSX makes a stock 200HP is in the electronics and fuel systems.
The real reason the evo makes 280ishp is that the turbo it has is bigger, and runs a lot more boost. It is a 16g and flows just as much as the evo3 16g. Lets just say that if you did swap it and kept the t25(stock 2g turbo) then you would make absolutely no more power than before. So with common sense just throw a 16g on it, and supporting mods, and get it tuned, and have a car that is FASTER than the evo.




it will not be cheaper. trust me I have an evo engine I picked up for free sitting in my garage and I've done an engine swap on an evo 8. Your first problem is that the engines mount opposite of each other. One the Eclipse the engine is on the drivers side and trans on the passengers side. On the evo it is swapped with the engine on the passengers side and trans on the drivers side.
If you were to try this, you would have other factors that would increase your cost significantly. Lets start with where the intake and exhaust are located. Your intake would move to the front of the car and the exhaust would move to the firewall side. this would mean custom fabrication of the subframe for the exhaust to be routed easily. You would also need a custom one off fabricated intercooler piping setup as well as one off exhaust since nobody mkes a kit for this. Then after you did all that you would have to figure out all the wiring necessary or buy a matching harness to splice into the car to even get the 300hp. there are a few more sensors and controls that help make that 300hp.
So long story short you would be looking at probably $2-3K just in custom fab piping and wiring. then add on the cost of the engine and misc hardware and bolts, etc. that you will find you need along the way and an ECU. For the $2-3K you could easily do quite a bit to what you already have and maybe even get the 300hp you want.
This is just my .02 take it for what you want. I'm not here to stop someone from their dreams. Just putting things into perspetive.
