Does anyone know exactly what size the throttle plate is on the XF throttle body. Ive read that its 75mm. Is this the internal or external bore. I want to attach 3" intercooller pipe to it for a EA turbo conversion. Also on the XF is the ISC external or attached to the TB.
If anyone knows of any other Throttle Bodies in the 75mm vicinity that can be bought cheaply (even new up to few hundred $) please advise.
