I am interested in purchasing a Garret Turbo for my 98 Integra GSR. What turbo should I go with in your opinion? I was looking at two of them. One of the two that I was looking at was the GARRETT T3/TO4E 57 TRIM W/ .63 A/R TURBINE and the GARRETT T3/TO4E 60 TRIM W/ .63 A/R TURBINE. Which one would be better for my application? Whats the difference with the 57 trim and the 60 trim? And at the top of the page it says,"OPTION: T3 5bolt TURBINE HOUSING", does this mean that I could make the turbo housing a 5 bolt downpipe? Thanks for your time and hope to hear from you soon. Thanks
