My current set up is a 04 gto swap with 1.75 l/t, 2.5 duals with x pipe no cats, eps 226 230 / 598 600 113 +2, built 4l60, 3200 vigalate, 3.54 rear, 255 walbro. I recently bought some afr 210's with 66cc cambers to do a n/a build. To go n/a i need to mill the heads so I need to decide what route to go before installing them. Realizing a good build n/a is around 500 rwhp, Iv been considering turbo having a lot more potintial. The car is mainly a street car with an occasional trip to the strip and autocross. If wanted to get 650 rwhp what do u recomend. Do I have enough fuel pump, what size injectors, are 2.5 duals lare enough? I would probally go to a Y pipe with single T. to keep cost down over dual T. Thanks for Ur help.

Lots of good info. Thanks Sounds like my 2.5 exhaust will do, but I need to wrap it.

 

If i go boost is it worth keeping the AFR'S. How much difference will they make over the stock 241's.
