I've got good news and bad news.... The bad news is that my turbo is starting to smoke/go out. The good news is that gives me a good reason to upgrade it. I have a choice between a T3/T4 and an upgraded stocker. Price is a major issue due to my monthly income to debt ratio. My goal is 400 or more HP at about 12 PSI. I don't care about lag so much, however I would like to hit boost at around 3,000-3,500 max if possible. I know how possible that is with the T3/T4. What size compressor wheel would I need to make a CT26 do that? Also, is the turbine wheel upgradable or does it just have to be modified? Thanks for the input everybody.
