What is needed? Will it fit? I am curious because I notice how much more room the 06 wrx's have in the engine bay compared to mine. I am also planning on using legacy gt gears in an 03 transmission, this should mate with the longblock and fit with no problem right?
the tranny will bolt up to the sti block no problem. the sti longblock will fit just fine. only thing is the sti has AVCS and your 03 wagon doe not have the wiring to hook that up. you can buy an adapter from gruppe-s to make it work i beleive. im no expert on sti swaps just yet. WJM may be able to tell you for sure.
