New project ( stock suspension 275 drag radial 72 duster)

I havent quite decided on what turbo we are going to use yet but at this point are leaning towards the Borg Warner S480 with the race cover and the billet wheel. It has proven itself to be capable of supporting 1300 rear wheel HP. We also have most everything needed to start building the headers, which will consist of 2" primarys and 3" crossovers. We also bought the IC Engine Works header mock up kit. It is a bit pricey but has been worth it so far. The first two tubes of the header have already mocked up in several configurations to come up with what I wanted and can be changed in a matter of minutes with no cutting of stainless elbows and no tacking. Thats all Ive got so far but in the next few weeks the headers will be tacked together and hopefully my mind will be made up on a turbo.
