The rb20 turbo's are good but also check out the tdo5 and tdo6 items. The latter can support 400hp and they are fairly cheap. I would think a stock 4age would handle 6psi if tuned correctly and preferably was intercooled. If these 2 were done maybe even 8 psi would be possible and around 50% power increase.
