After I made my gvr4 stable on the road. Again I got hungry for more power. So I upgrade to big 16g & 2g ported exhaust manifold, External dumper, 3"exhaust + Methanol & Nitrous kit. I am still more hungry for power. So I am thinking of doing 30psi of boost. My engine is almost stock except the HKS264 Cam. My fuel system should deliver enough fuel as I am using 255 walbro fuel pump, 650fic injector & AEM AFPR. My induction also should deliver enough Air. Using 3g Maf, Cyclone intake & Racing Air filter. I am worried about the engine internal. It may not handle 30psi of boost. What should I change to let it handle that.
