Default WRX turbo set up on 2002 impreza

A buddy of mine has a 2002 Impreza and wants to turbo it. I have an 07 WRX and we wanted to know if my stock parts (uppipe, downpipe, turbo, intercooler) could be used on his car. Does anyone know if this is possible? What other work would be involved?

you sound JUST like me and my friend who has an 06 impreza. We called around and yes they would work with additional part needed but in the end its not worth it (cost wise anyway). Sorry to burst your bubble. If money isnt holding you back then yes you can do it but few have seen good results for an extended amount of time. Impreza 2.5i engines just were not made to be turbo'd and last.

I have all my stock parts and he wants to buy them off me. What besides the uppipe, turbo, downpipe, and intercooler is needed? If it's possible he just wants to get around 6 psi or so out of it. Could the 2.5 handle that?

If I remember correctly you will need at least a wrx new frame brace, wrx oil pan, umm all turbo lines, intake and sensor. I believe it gets meticulous from here on out. The parts I listed your friend would need to buy because you will need them as well.

Totally forgot about oil and coolant lines. The only thing i'm not using is the oil inlet and intake stuff. I wouldn't even know where to begin with to get oil and coolant to the turbo. I thought I was gonna make some money selling stock parts. Thanks though.

O obviously injectors and pump as well.

If you are replacing almost everything outside of the block (intake, exhaust, turbo, fuel, rails) and such then he has to find less extra parts.

Dont forget the hood and hood scoop since he will have a TMIC (yours will not fit)
Are exhaust and hangers in the same location?
Will he need a boost solenoid now because I assume your gonna keep yours.
Possibly different ECU or an amazing tune at least.

This stuff adds up quick for a not so great power gain and jeopardizing the engine life

I've already got everything off my car including all exhaust stuff, turbo, intercooler, intake, boost control solenoid, and injectors. I was gonna sell him everything if it was all he needed but now that I think about it it doesn't sound that easy. Getting a tune would be easy and the boost could be controlled manually (never a good idea though) but that's all the easy stuff. Figuring out the oil and coolant stuff sounds like it would be the most difficult to me. He already has a wrx hood though so he's ahead there but it all still sounds like too much work especially because I'd be the one doing all the work.

Yea if you are doing all of it, it will take alot of research on your part and probably a decent amount of down time of his car.

You still have to find what exact frame brace to get for him, and i think new engine mounts. WRX oil pan should not be that hard.

The oil and coolant lines may be tolerable, order them from dealer or genuine parts store and follow diagrams. Might need new coolant reservoir and pump? Maybe you can keep the same radiator..
