x16xe what size throttle bodies

[Basil91]

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.

45mm

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

I've got 42mm gsxr bodies for my 1.8 16v

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

[Basil91]

yes, i thought the SBD kits were 45's.

Wheres a good place to get a manifold?

[Will F]
