I have a garrett gt30 turbo. It's a .70 a/r 52 trim compressor wheel. and an 84 trim .63 a/r turbine. The turbo is rated at 480 hp on some sites. Do you think it can make over 500 hp? I have a really good motor and turbo setup to match it up so I'm thinking it might be to small. I want to be able to run low 11's and a 10 would be my ultimate goal. I have a built gsr motor 2.0 liter 9:1 compression. Full race turbo kit all in a heavy 00 si. What do you guys think? Should I get a bigger turbo or keep this one? let me know guys thanks.
