well i'm lookin into a new turbo. i have narrowed it down to the new helix 20g, fp green , or the ultimate racing t3t4e kit. really thinking about the UR kit. my goals are a turbo i can hit 390-400whp. my current mods are vf39 , 3' turboback, lightweight pully, meth injection, cobb protune. really like the t3t4 kit, just wondering if thats a good kit or turbo? like the kit cuz it comes with everything (cold air intake, down pipe, external wastegate, and turbo for 2500). also wanted a little room to work with in case i wanted more. and i did search but there not much on the t3t4 turbos. and before people say anything about the tranny, i'm upgrading that too. just a little later dwon the road with ppg gears. just wondering which turbo you guys think is the best for 390+ whp?
