I am currently running a small 16g. The bolts for the J pipe are stripped out and the compressor wheel is damaged. The turbo has absolutely NO shaft play and I think it would be a shame just to get rid of it. I was thinking about upgrading the compressor cover and wheel to a 20g wheel/housing since I need to replace it anyway, but I have read that the 20g wheel will overrun the tdo5 7cm turbine housing. I have already ported the turbine housing out but there is still room to port it out more. Will porting make THAT big of a difference and would it be a real waste of money to go with the 20g or should I just go with the 18 or evo 16g? Id prefer the 20g out of three because it gives me room to grow but I also don't want my turbo to be inneficient. If you post your opinion please state why you think it will be better. This car is also my daily driver.
I also plan to upgrade fuel injectors soon...switching to e85.
Im looking for about 400-430 whp with the new wheel and cover. My car is a 97 gst...mods include a 1g 7bolt engine, 1g TB, ported 1g head & 1g intake mani, arp headstuds, cometic hg, Punishment fmic, evo 560s, wally 255, apexi 3" dp, 3" exhaust no cat/muffler, dsmlink v3.
Thanks
