    Default x16xe what size throttle bodies

    Hello,

    I am in process of building a x16xe engine, spec will be ported and polished head, canems ecu, reprofiled cams, exhaust manifold and straight through exhaust.

    I am hoping for 170+ bhp, what size ITB's should I use, I have the option of 40, 42 or 45mm.

    40 should be enough for 170+hp if you need flat torque. Over 200 is 45 needed.

    with 40s you'll be restricted to around 150.

    The SBD kits are all 45mm
