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.

how fully built? 72-70mm, if its going to be an all motor monster

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?
