I have recently finished all my modifications on my SR20DET s14 blacktop. I am trying to get in the 350whp range and I can't seem to find any answers on howich boost I can safely run. I have upgraded the fuel system, 740cc injectors, 255 fuel pump. Front mount intercooler, z32 MAF, 60mm Garrett t3/t4 turbo with top mount turbo manifold, metal head gasket with head studs. I know the safe limit on the stock turbo is about 15psi with the upgraded fuel delivery, but what is the safe limit for the full turbo system upgraded?
