Picked up some FB's....what to do, what to do

[djmtsu]

I have decided to boost this little 12a until it blows. I am getting an S4 turbo and manifold, and fabricate a 12a-->13b adapter for the exhaust. I already have an RE-Speed pedestal for oil supply, and will tap the front cover for return.

I have another thread asking what it takes to boost prep an RB Holley, so far with no useful responses. The Holley Blue pump I have is enough, but I am either going to need a rising rate FPR, or modify the Holley FPR I already have. A local guy has a turbo hat for the carb (assuming we can use the Holley).

Question: where should I source the coolant feed/return for the turbo on the 12a block?
