decent gains but dont bother with the 2.5 manifold, just bore out the 2.0 instead.

Hi, can you be kind enough to give some direction, like a diagram some measurements, how much and where to bore the throttle body of 320


I am using a 325 engine on a 320 inlet manifold and throttle body. I would love to do this exercise.

TQ

im a bit confuse matey. if you have a 325 engine, why are you using a 320 manifold and TB?
anyways to bore out the manifold get a 325 tb gasket and put it against the manifold and using a dremel or similar, incrase the size to the outline. do not do to much of the bottom section as there isnt much to reduce.

the manifold is the silver thing with the 6 pipes coming off it

Ah it is a long story !!

I just changed the engine block from 320i to 325i .. All the rest of the parts still belongs to the 320i .

the TB gasket you are refering to, is that a rectangle kind of thing stuck to Manifold?
