is there a big differnace?

it will be ran on a stock ls motor

thanks

i have in hand t3/t4 .60 .63 4bolt
i might trade for the 50 trim


btw can i run 4 bolt with the revhard ac/ps manifold?i heard it wont work and i will need masiveshaving of block?

 

On the second one you must mean t3/t4 50 trim .50/.63. That has a T04B compressor housing on it. The other one has a T04E housing on it.

The 50 trim will spool slightly faster, but not by much. They both have the .63 AR exhaust so make sure you have 3in exhaust to avoid having late boost. Unless you are boosting pretty high, there won't be much of a diference between them.

It doesn't matter if one is 4 bolt or not, that won't effect how much you will shaving off the block. Haven't seen a T04B mounted on a revhard, but the T04E will need a little 1.5" cutout from the webbing on the block near the engine stamp.

 

i was told the 4bolt on pass side will make me shave alot off
but a 5 bolt driver side i will need to shave little webbing only
