So im building a h2b project. I am un decided on what to do. What do you guys think would give me more power? h2b with a built head and ITB OR Built head with 12:5:1 pistons? Ive read up on the obx itb and it discouraged me to go with itb because oftheirpoor quality. But ive heard that the twm itb are pretty good but 1,800 sounds ike alot for a niceintake manifold. What do youguys suggest? please help

 

What H22 are you starting with?

 

Do the pistons & bottom end work. ITB's will give you nice throttle response, but you can make similar power with a well designed intake and manifold. Plus, you can always switch over to ITB's later without a lot of hassle, but if you want to do pistons later you will have to pull the whole engine.
