So I have 2 SR20DET, one black top one red top, the black top is running fine but unknowen whats been done or if anything been done to it.

The other SR (the red top) has a blowen head, but bottom ends been rebuilt (new bearings and rings I think), so I got a new head (2nd hand seems good condition from inspection) and thinking of rebuilding it, I was thinking of using the red top in my project car (as it is without an engine).

Ok so my aim is for about 320hp - 350whp just wondering if OEM gasket is good enough for this as the price differences is about $200, and since if OEM is good enough one of the engines are going to be sold anyways.

so which motor should I use? and if I'm to use the red top which gasket?
