I was wondering if anyone thinks it is possible or knows of someone who has run a 12.9 or lower on a turbo stock internal B18B dc4 integra? All I want to do is add bolt ons with slick radials. I Plan on turbo at 9 psi with Intake Manifold, 70MM TB, Full MSD ignition, 450cc injectors, and the only thing internal would be a set of crower turbo spec cams and upgraded valve springs and retainers. Would it be possible without the cams and valve springs? Any help at all would be great. If you know anyone that has could you please let me know of their setup.

9 psi would be close...

but there are LS's making 300 whp on stock internals, at that point it should be no problem to run 12's.
