I just picked up a 90 Galant GSX from my friend. we've all been wanting it so somebody can turbo it. well i got it now. long story short, i'm going to be ditching the engine all together for a turbo one from the get-go. now aside from the obvious things that would need to be performed like ecu, engine and whole turbo and ic setup etc.. i've got a few little questions i'm trying to work out. if anybody knows where i can find any specs other than the obvious or knows about or has a galant gsx, i've got a couple questions.
1. i have heard that the whole wiring harness is required in order to do a 4g63t swap right. if so, could one from a 94 frontwheel turbo laser work? i mean assuming i had 91+ engine so all of the sensor connectors would be correct, otherwise a harness from a 90 awd turbo? if at all?
2. what are the specs on the driveline. as far as how strong/differences in the transmissions and their gearing. also, i'm assuming the rear end is a non-lsd 3-bolt. (i haven't had a chance to pick apart the car yet or even get it in my possesion but i wanna get started on this right away)
3. is it true that the n/t throttlebody needs to be modified at all in order to handle boost? (i wouldn't be running more than 19psi or so at the most) they're just a little bigger than 2.5" inlet. and i've got an extra that i was going to run on my 90 tsi as well if possible so it'd be easier for i/c piping and less gaskets and larger diameter.
any help or input anybody could give me would be really apreciated
