I just got back from Ken Dutweiler's shop and he was starting a buildup of a TA twin turbo block using stage 2 heads. The cubic inches looked to be about 270 and he was using a Wilson intake ($4500) with a 90mm TB. I did not get the time to get the specs. on the cam or turbo's being used for this project. What stuck in my mind was the 1800hp that the customer wants!
