ok so this is my setup so far

d16a6 bottom end
d16y8 head
tdo4h 15g modified greddy turbo
act lighted flywheel

Next on the list
dsm 450 injectors
get the p28 chipped
bov
and intercooler

Whats the max psi i could run on this setup at what roughly has this setup yeiled in hp. And were can i get the exhaust flange forthis turbo so i can weld up a manifold for it.

 

You will need A real good tune the compression with that combo is up there!!!

 

cant i get a thick head gasket to lower it? or get dished pistons

 

youll get more hp if you leave it with a good tune, but yes you can get a thicker HG.
