What turbo will give me the quickest spool but can also hold up to 8000 rpm and about 250 whp? I was considering a GT28R, but can't figure out an estimate on full spool time for 8 psi. Also, are internal wastegate bad? Will it spike at 8-10 psi?

 

? anyone?

 

Id spoon feed you this but its too late at night.Instead try searching.Ok since you obviously dont know how to search heres a little help.WWW.homemadeturbo.com
Theres plenty of info in there! Good luck

 

what kind of manifold do you have? a t3/t4 in .63 ar trim will spool around 4.5k and full boost all the way to redline. On a stock motor, I've seem them produce 225 whp at 7psi

 

custom log manifold...
