I am swapping the 4g37 with the 4g63,in my 94 eclipse base, no wi need to know what exactly i need to buy, and maybe some pointers as to how to do it, i want to buy the engine then build it for a few months then drop it and hopefully have it good to go by next spring.

I'm sure you guys get this question alot, sorry

 

several things. but first let me refer www.vfaq.com. a great site for your needs. well, you'll need to see if your current engine harness with support the 2.0l. cause you're going from 1.8 to a 2.0. not very many parts from the 4g64 wil swap to the 4g63

 

i know i need a new harness, but i wonder if i need a tranny?

 

i think the bell housing bolt patterns are the same. but don't quote me on that.

 

if you can get the whole motor (block, head, fuel rail, injectors, intake manifold and such) all you have to get is an ecu and drop her in.

 

ok thanks, so dont i swap something over from the engine i have now? Like a crank or something like that, and also how do you rewire the car with the harness?

 

And how many bolt engine do i need

 

any 1g motor. but if you can get a 6-bolt motor.( number of bolts on flywheel)

 

Can you tell a major differance in the 130hp engine compared to the 93hp? I just want it cause they sell alot of parts for it, and the car is totally gutted so it is very light

 

well youll have a 1/3 more horse power.
