Im looking at buying a forged 2.5 engine for 2006 hawk sti.

Now my question is, the forged engine comes with version 8 avcs heads which are 2.0 heads, will this setup fit straight into my 2006 hawk 2.5 sti - as in sensors etc?

thanks

 

2.5 STi has DBW throttle and 2.0 has cable throttle so the camshaft sensors and camshafts are different , the 2.5 has 3 wires and the 2.0 has 2 wires.
I'm having the same issue at the mo fitting a 2.35 with 2.0 heads to my Foz 2.5.
Tim at JT inovations is making me a conversation loom at the moment so you could give him a shout.

 

Yes i found this out last night, i dont want to be messing about, i just want it to straight fit.
