Just some questions about the BBTB conversion fitted to the 2.5 M20's
What car/engine is the BBTB from?
Does the opening on the inlet manifold need to be open out further to suit?
What hoses need to be used to connect it to the airbox etc?
Cheers in advance for your answers.

The Throttle body starts off as a standard M20 2.5 one. A nice engineer chap called Ian bores them and fits a bigger butterfly. You can contact Mr. Salad and buy one from him via the e30zone shop.What car/engine is the BBTB from?

All the standard ones. The O/D is unchanged.What hoses need to be used to connect it to the airbox etc?

Project E30 I've just replied to ur Q's in my thread mate.
Ste ur spot on what a difference it make's.
its a straight forward swap over of the throtle body's as long as u use that little plastic pipe/ straw (thanks for that Ste i would of been scratching my head for ages)
All i had to buy was a new gasket
Thanks again Ste
