| lower the compression. Seriously. unless your going to run alcohol and c16 all the time, with like no timing. Lower the compression. You will never add 100 hp on pump gas to a 12.5:1 motor. Just not gonna happen |

| assuming the block will take the abuse i would look into zex nitrous system. either that or lower the compression and go boost. |

| it is not a matter of being able to spool a turbo, it is a problem of the static compression being so high that under boost the dynamic compression gets so high that most fuels will not provide enough knock resistance. If you were building an all out drag motor that was going to run alcohol or nitro than it would be fine. running on pump premium and possibly even c16 you will end up with a blown motor. |

| a B18B is not a vtec head. Stay with the B16A head that you have. If you can get a B18B block than you can buy an LS/VTEC adapter kit to put your B16A head on it. |

| Since you already BUILT your B16A2 then you should tune it for a 100 shot of NOS. I would prefer a DRY SHOT being that the compression is in the 12's. Build the head with some stage 3 camshaft, I prefer Skunk2 but you can go with whatever fits your budget. Dont forget to get the B16 head ports Matched and a 5 Angle valve job. For those Stage 3 camshaft you will need to upgrade your valvetrain so i suggest you do so if you want to see anything close to that 100whp gain. Skunk2 manifold and 68mm throttle body 2mm more doesnt make a difference but make you lose a bit of lower end torque because it will cause you to bog considering that you might do that 5 angle valve job( which is better for Air Flow [ in my opinion ]). That 100 shot should put you some where in the 300's |

Forget Turbo, you said you already built the motor. I Dont get what you are trying do? If you want a B16 with over 300HP+ then get a 1.8 STROKER KIT Darton Sleeve Stage 3 camshaft 5 angle valve job Upgrade valvetrain Kit 12:5.1 | |
