awd92gsx Posted April 22, 2002 Share Posted April 22, 2002 What seems to be the ideal choice for compression ratios on 280ZXT engines? I am probably going to be running running 9:1 on a T3/T4. I called Arizona Z Car and asked if they kept pistons in stock and told them I wanted 9:1 turbo pistons...he must know something I don't know, or I must know something he doesn't know...cause he appeared to think I was crazy...or stupid, or both...

fl327 Posted April 22, 2002 Share Posted April 22, 2002 stock zxt compression is 7.3-1 or something like that, 9.-1 will work, thats what that hoover turbo car is running, but hes got billet bottom end stuff and custom everyting, i think on 91 hes pushing close to 500 with "only" 15lbs on a t4 Quote Link to comment Share on other sites More sharing options...
