Turbo 440 duster

If I had to do it over I would go with twin 70mm with .96 housings. Mainly because it would be easier to run two 3 inch downpipes.
I am going to try the S480 and if it doesn't make me happy then I will upgrade to a bigger single.
The car is strictly a street car though and because I am running a stock block I was shooting for 7-800hp, If I decide to go with a bigger turbo I will build a different engine starting with a world block. I am building it more pro-touring and with a 46rh overdrive tranny so I can drive long distances comfortable.
It should be a fun street car though :-D
