Throttle bodies

[big_c_43]

Hi everybody, i have an 1985 202 EFI VK i was wondering wot is the size of the stock throttle body and is it worth putting a larger one on ( with respect to fuel consumption versus power gained) also is the VL throttle body bigger than the VK ( a friend has a VL and is upgrading his throttle body so i might get his real cheap) one more question is it an easy conversion?

This is a little errelavant but i saw on a ford XF a twin throttle body is that legal?

Thanks

its an ok upgrade, definatly not going to fry tyres lol.
standard xf tb is a good one to use idk about vl's.
from memory vk's are 60mm and the xf is 80mm.
