its a small kit i did most of for him. gt2871r turbo. drop in wossner pistons, ported head, stock cams, stock rods etc. he was running about 330 hp. no boost controller. we put the next size up spring in for me (350 hp) and i managed to get a 232.39 mile and 242.83 1.5. its a fun bike! that little turbo comes on quick. he can get 110 octane at his local gas station, so runs that in it. Im sure he will go mid 230s on it with a little more run time. hes barely had a chance to drive it since finishing it.
