    I'm looking at Erick's racing TB's but I'm not sure which size to get. I don't plan on boring out my Skunk2 intake manifold at the moment, so that portion will remain 64mm. So with that in mind, which size should I get?
    68-66mm
    70-68mm
    72-70mm

    This is going on a fully built B18C1.

    P30 pistons stock bore (11:5ish CR)
    ARP rod's/Bolts
    Micropolished and balanced crank
    Portflow head
    Skunk2 IM
    Crower stage 3s
    P28 ECU reprogramed by Erick's Racing :D

    it's pretty much OEM stuff except for the head. I just don't want to pick a TB that's too big for my application.

    So I should get the 72-70mm? Even if I plan on leaving the intake side of the Skunk2 manifold the same 64mm?
