hey man,

Sorry for the late response. my email is [email protected] if u have further questions.

I chose the gt3071r over the gt28 because of hp limitations the 28 had. The spool up time (bottom mount t25/28 manifold)was hardly noticeable to the gt28, and had better top end power. Honestly there was not a downside to this set up by any means.

hey bro, i had a question with your t25/28 flanged gt3071r setup, as i am going to be doing this setup with a bottom mount next week. Were there any downsides to this? it seemed like you somewhat supported this by saying you choose this over the gt2871r setup. The questions are: is this laggy and where did the turbo begin to spool? Is it as powerful on launch as a gt2871r and is it fun as far as a street car? im coming from a stock t25 but going wth the same as you had (810cc inj., keeping the stock intake manifold to keep a little more bottom end torque, and of course a bottom mount t25 flange megan exhaust manifold). please lmk. thanks
