[mirkoelek]

i have 98gsx, evo 16gturbo and all fuel modes with dsmlinks (650cc inj) , web cams
stock engine, what is the max boost i can go with

 

[project_tsi]

do you have a fuel pump and FPR? but 17 or so should be fine, on the stock HG and bolts. easily 20 or 22psi w/ a cometic HG and ARP studs. is your boost creeping? what WG are you using?

i would say 20PSI SAFELY on stock headgasket and head studs. If you want you can always get ARP headstuds and a metal headgasket and max out ur injectors...or you shortblock
