From: Leeds - It was 562.4bhp@28psi on Optimax, How much closer to 600 with race fuel and a bigger turbo?

there may be a problem with cam and crank position sensor wiring if you do swap the ecu...

Speak to Trout.

P1 and STi 5 ECUs are interchangable which suggests that electronically the engines are except any differences with ancillaries. The P1 ECU would not be a bad idea anyway, and easier to source when you get the P1 block (and safer than an STi ECU). Can't think of any issues with your proposal, but I am more electronics/ECU inclined. One thing though - are there any issues with ABS/diffs which may/may not affect you?
