Not good. Don't do this.

I know rb20s can rev to 9k safely

i would be more concerned about the valve train, like a hydraulic lifter fainling!

What oil pump are you runing ?? Crank generation (long or short oil drive) !!! Those are the two most important point to have when over revving a rb !!!

rbs14kouki · 11-04-2011, 12:11 AM

Tomei pump , good crank model , crank poulie (ati/Ross) bleu print engine ready for high rev !!!

Stock form not so good dont go over 7500 / 8000 or if its at 8500 do NOT bounce on the limiter
