I did search but could not find a solid answer for my turbo set-up. My current turbo is a Garrett T3/T04E .63ar/ 57 trim turbine and .60ar/76 trim compressor. I've seen a lot of posts on how well the .63ar/57 trim will work well with the stock B18c1 for spool up but what effect will the compressor's .60ar / 76 trim have on the overall performance of the turbo? I'm assuming more flow from mid to top end but not sure on this. My target goal is 300HP (~10psi) while keeping the ride daily driven and some 1/4 track use. I just want to get a good idea of what to expect before I finish up the project. Thanks.
