throttle Body

Whats the normal stock size of the throttle body on a 1.5L d15b2 engine.

For any d-series engine it is 62mm. And for a B-series it is 64mm.

For any d-series engine it is 62mm. And for a B-series it is 64mm.
I don't know where you're getting your info from, but you are way off. The d16a6 is only 55mm, so one would assume that the b2 is even smaller than that. And the B-series are any where from 58mm-62mm. Hell even the h22a only has a 60mm throttle body.

So what is it?

the stock size on throttle body it is 62mm on the D-series engines and its 64mm for the B-series engines

damn thats a big difference

This is the correct info, The stock one can actually be bored out to 58-60 mm if you are doing a pretty decent build up.
