Im looking to keep my A/C. I have a 97 HB with y7 and y8 IM. Im going to do a custom set up, and I want to know what turbo will allow me to keep my A/C? And what turbo exhaust mani goes fits the turbo? My goal is, stock internals, 8 psi no more than 10psi, and 200 whp (13s with street tires). Im thinking t25?
