Why do you have 550cc injectors on your build? We made 205whp and 142tq. with skunk2 stage 3, wiseco pistons 11:5:1 , 310cc injectors, b16 head with s2 valvetrain, dc sports header, act clutch, b16 tranny,type-r im, type-r tb, tuned on crome pro in a DA and went 13.6 @103.5mph on drag radials with a 2.1 60ft. by the owner. I recommend you sleeve it ,b20 walls are thin, so be careful and be smart with how you drive. Not saying you can't get it to last without sleeves, but a lot of people blow them up or crack the sleeves. Remember with hybrids you need to have it built correctly with a great turner and tunning device.
