I am going to tdc in NH a week from today to get my car tuned. Its a 92 hatch with a built a6 block with stock z6 head. Right now I am running 12psi but boost is addictive so i want to turn it up. My block consists of eagle rods, srp pistons, yada yada yada. The compression ratio is 10.5:1 and im running a to4e 50 trim. I was wondering what you guys with built d16 motors run especially the ones with higher compression. I am shooting for 350-400whp. How far should i push it? Psi?

 

do you have sleeves? if not i 've never seen them last more than 12psi, cause of head lifting.

 

stock sleeves. I had the head lifting at 12psi but it was timing because bailhatch (tuner) lowered the timing and it hasnt lifted since.

 

Up up and away.
