what size turbo will be good for a single cam turbo build? i dont want to wait til high rpm's for boost... thanks i have a t3/t4 .50 trim now

 

your 50 trim will work great on your D series...it should provide good all around power if you couple it with a good manifold. I'd recommend something like what i have...a shorty ramhorn of some kind. I know that SLS and SPoolin both make great versions of it. I run an SLS on my GSR daily
