It can be surprising how much HP cam be made through the stock cams, and ports.

I knew of one C2 that just ran a 60-1 Turbonetics turbo, with Borla straight through muffler that was all stock otherwise and made 390rwhp at 1.1 bar. Another friend with SC cams, flowed intake manifold but stock ports, and first generation HF that made 430rwhp on CIS.

If you can keep your boost up and with the increased turbo efficiency make 400# of TQ at 5500rpm, that would be 420rwhp.

I wonder how far you can go with your stock cams and custom double core IC before it starts costing you to much. Your EFI should help a bunch.
