fast 6's are not expensive. I am doing a turbo 6 and im only in about $250 but am doing all my own fabbing. Supra turbo, 2.5 180 bend for the exhaust side off the stock log with CT-26 turbo flange mounted on top (3/8 plate) 350 CFM holley carb (off an old ford truck, drill PVR's out to about .076 and remove choke plate and fill linkage holes to make top airtight) some sort of carb hat (probably most expensive part of the whole deal) pressure line from turbo to fuel pump weap hole for boost reference, silicon hoses from the turbo to the carb hat, blow off valve, and oil line and dump from turbo. Need a 2bbl intake for the holley, dont know how to mod a 1920 or a 1945. Lots of shopping around, lots of time...What do you have to lose?
