i know me and my buddy were gonna do it in a rex..the z6 head on a a6 block and the p29 pistons is rumored to have close to 12.1.1 compressionOriginally Posted by 1SOL2NV
neither the z6 head or y8 head flow any better ,.... its the intake manifold ... the y8 flows better ... the head flows the same .so get a z6 head with a y8 manifold .. but i agree with these guys ... coming from past experience your better off leaving the d15 alone and enjoy the mpg or go b series .... i spent close to 700 $ on my mini me .and it was a WASTE OF MONEY then and it would be a waste now unless its gfoing into a CRX ... if not .. your wasting time ..
