Ok so im going to be on the lookout for a set of cyl heads from a ver 5/6 STI for my new build.

im after information on whats the best to unleash power/effiency on cylinder heads.

cams?
adjustable cam pulleys?
porting and polishing? (IMO, cant see this doing much)
uprated parts?

what did you do and what gains/advantages did you see?

Thanks

 

Most of them seem to crack near the plug area, you need them clean to see it tho.

 

If you are considering a Solaris ecu, just be done with and get some AVCS heads from a newage sti.

Banny

 

Iv just bought a simtek Banny, but solaris could be on the cards for the new one but not til next year.

what do i need for them heads on a classic car do you know? whats the advantages also? was going to try keep it simple if im honest but im open to ideas.

 

Thanks for the heads up.

 

Just need to run four extra wires to drive the avcs solenoids, as for the advantages better spool, more power and the heads have shimless buckets as standard.

Banny

Bug Eye (2000-3) STi has them (I think? ).
