Ok I am planning on boosting a stock block b series. Most likely b16 or ls. I have a turbo that I might use but I am wondering if it will be too big for just stock boost. It is a dual ball bearing 63 a/r hot side. 70ar compressor side. So my question is would this turbo be too laggy for a lower boost application, and what should I expect if I use a turbo like this. Thanks!!

 

I'm running a .63 trim t3 on the hot side and .60 on the cold. It buids 10psi by 4500rpm. You gotta tell us what type of turbo it is manufacturer and size.

 

not sure of the brand.. its dual ball bearing like i said, and .63AR Hot side .70ar cold side 82mm exducer wheel size, 61mm inducer wheel size .
