OK trying to get better idea of possibilities,,,,

[MonzaRacer]

What I am building is a 77 Monza, air ride, V8 auto:
specs:
61 283 040 forged flat tops
reconed stock rods good bolts
factory steel nitrided crank
squared and bored w/tq plate
Found a set of 1416 305 58 cc heads will have 1.84 intakes/1.60 exhaust
LT1 intake
thinking about a turbo set up.
Found a used TO4 based but dont have much more info on it but still thinking of trying a turbo, small one just for fun.
And trying to get the Flex FI doing too.
Any good ideas would be helped, had even thought of twin turbos possiblies.

Pick up a used 67-70mm master power unit or even a new one. They are around 600. Fab the rest yourself. Use knockoff blowoff valve and wastegate to keep the cost down. You could probably do it for $1000 or less if your thrifty. Ebay intercoolers are ok also. Just stay far away from ssautochrome on ebay when buying the actual turbo.
