ok so im currently running a d15b7. but im building a Ls/vtec motor to be boosted.. but since i will own the d15 i figured why not see what i can do with it too so i figured i would put a mini me head on it and wire in vtec bore and sleeve the block was thinking about benson sleeves and CP pistons for the d15.. as my ls/vtec already has them. but my question is what else could i do to the d series motor? i would like to see 250-300 HP out of this motor. and the benson sleevs can handle 50 PSI of boost.. so what else could i put in this motor to make it.. different..
