Hi all. Ive done some research and just havent found the right answer. I have a fully built H23 witch Im adding right now crower turbo cams. I have a t3/t4e 57 trim 63 on hot side. I had it dynoed tuned by raceline and ran out of turbo at 15psi. Car made 310whp on a Mustang Dyno and Torque was almost equal. I want to hit the 400whp area and need some advise on a new turbo. Must be an E cover becuase of manifold Im using and 4 bolt discharge would be nice also. Any help would be appreciated. No ball bearing either.

Thanks

 

t3/60-1 would work well for you...or the STC Silver Surfer. It really depends on your budget. There are great turbos like the S256/S258 on the market. They're non-BB but will hold their own against a similar GT-R series turbo. They're around the $1200 range last i checked...

 

What ar on the hot side should I go with?

 

it depends on which turbo you go with...generally people use a .63ar turbo. If you look more into the S2xx series turbos, you'll see that they dont have the standard .63ar, .82ar, etc....instead they have a .55ar, .70ar, .76ar and .85ar.

 

A precision sc6152e would work just fine. The local mustang dyno reads 25% lower than our dynojet does so I would say you are not too far away from your goal as you sit right now.
