thanks for looking, so the dd is a 07si (z3) i have to do a head job on it (tensioner went out when driving).....i have a full skunk2 topend for a a3 /= what im wanting to know is can i run the a3 cams as long as i use the a3 girdle and if that all will work out, will the a3 s2p2 cams make better power then my stock z3 cams? any real knowledge would be greatly appreciated

 

the a3 only has vtec on the intake side and is not performance oriented. think of it as the newer version of vtec-e.

 

thats what i was needing to know. thanks. i didnt know it it just wouked off the rocker arms differently or what it did. i put the cams side by side an didnt know whe i needed to do, i guess it will keep the stock cams for now lol thanks again
