STi 3/4 heads and cams will do you for around that level, we can supply them pre chambered for your 2.5 engine and gas flowed should you wish.

What are std unfettled STi v.3/4 heads (I'm thinking cleand up 2nd hand ones) good for, bhp-wise?
Do the v.3/4 heads have the same bolt patterns to suit v.1/2 inlet manifolds and headers.

V3/4 is wat you want.
And yes same bolt pattern as yours. V1-4 are same. V5 on changed to the staggered bolt types. The P1 is v5 so won't fit.
I've a set of V3 STi heads.. £400 plus p&p
