Throttle Body Size for 2.0 Zetec
whitestu - 2/11/08 at 09:12 PM

Are 36mm bodies too small or just about right for a 2.0 Blacktop in standard tune?

Thanks

36mm sound's about right to me

Ive got 38mm gsxr 600s on mine and it seems to go ok, I am also running with speed density mapping with good results rather than having to use Alpha N like some do.

respaced to fit a modified plastic 2.0 Blacktop manifold and fuel rail / injectors.

I used jenvey 40s on my blacktop 2ltr. Gave better low down torque than 45's but sacrificed a bit on top end.
