Just curious if anyone on this board is running a straight T4 turbo in their daily driver (stock internals), and if anyone is , can you give me some feedback on your thoughts and opinion. I know people will recommend using a t3/t4 instead, but i strictly want to hear from people who are using straight T4 turbos.

 

A straight T4 is useless on low boost motors. T3 stage III/V AR.48/.63/.82 setups easily outperform T4 O-trim AR.40/.48/.50/.58 housings. Now if you have a built motor that will be seeing lots of straight line action a T4 hotside is the way to go.
