Throttle body size????

[locote]

im gettin my cyl head PnP, crower cams, Skunk2 intake mani, and it will be tuned with hondata.

would a 70mm throttle body hurt my power potential + torque
would i be better of with a smaller 1 or would the stock 60mm one do???

its a GSI teg B18B.

thanks in advance for the help:)

i rekon 70 is to to big... you cant go wrong though getting a type R one there around 62mm if thats too small mayb bour it out to the same mm the intake manifold is..anyways thats my 2cents...

i got choice of stay with stock 60mm. can be bored out i guess.
62mm
65mm
68mm or 70mm.
all round same price
65 mm looks like a nice upgrade
but it prob give same results as the bigger 1s but they all cost same.
so i thought might aswell get the bigger 1 if it wont hurt
ill be using a SIR aswell

65mm (butterfly) would be good for the build

65mm (butterfly) would be good for the build
Yes and will match the Skunk2 intake manifold perfectly.
