    looking for a motor!

    Hey guys, I have a 2002 wrx. im looking for a motor that I can drop in it but I really wanna do the 2.5
    does anyone have any idea where I can get one for a reasonable price? Also if I do a newer motor will the
    diff control work?

    thanks
    Leo

    Hi Leo and welcome to the club.

    You won't get any kind of differential control without doing the STi transmission and ancillaries.

    I don't know of a good source for motors, but doing the 2.5l block with the WRX heads ("hybrid") used to be far from a casual affair. I vaguely recall some more recent trick maybe though.

    Search Nasioc classifieds. Also search Ebay...find a seller that has good feedback.

    Running the hybrid 2.5L block with 2.0L heads is fine as long as you have the heads machined by a shop to match flow.

    If you're wanting diff control, you need an STI transmission (DCCD and controller) and all the goodies to go with that.

    Well what are you trying to do?

    Sounds like you want to swap over the complete driveline as opposed to just the shortblock, which is what we were eluding to with the Hybrid build.

    If you take the entire driveline route, you're going to need to do the entire wiring harness as well, which is a PITA, among MANY other parts. Not a simple task (or cheap).

    Here is an explanation of what it takes to do the 2.5l - you use your current heads which avoids the wiring harness nightmare.
