no, e = 50mm, i = 60mm

is it true you can use an E TB for an early 318i injection system with little modification?

[Ryan Stewart]

Dont know on that but its REALLY obvious the 325e and 325i TBs are different when you see them. The 325e TB will fit inside the 325i one and the 325i one has an extra vacumm port on it for the ICV.

can anyone confirm or deny this....

They are both the same they both open and let air into the motor. Same size no but same idea.

I have an "i" intake manifold and TB for my eta, and you can really see the difference when seeing them. The eta one doesnt look like it could be bored to the spec of the i one when you see them.
