we'll see. you information looks good on paper. but so do all those people that say you can only run 7psi on stock d series. i can see in a supra that a ct can only support 260hp. but if that turbo were on a d series, i bet i could make over 300 on a stock ct26. I sent my engine to the machine shop today. when i put it back together and make a manifold for one of my boys ct's. ill try it out. 20psi, even though its pumping hot air, will make good #'s. its stoopid to fight over the internet.. so look for my thread in a week or so.
