Im looking for some one to shed some light on this topic. I have the chance to buy the stock heads, turbo, uppipe downpipe, intercooler, intake manifold, fuel rails & ECU off of a USDM Sti, (06' I believe.) What other parts would I need to swap these into my 99' 2.5RS (Phase II) Sohc motor. I know I will probably need forged pistons and rods, and what kind of compression ratio will running the STI head on my RS block give me? Anyone with experience or advice please help. Thanks.
