Do i have SETA engine?

[Lyrred]

K cool cool. At first I was confused as to what seta was. Thanks for answering my question. I thought seta was a variation of the I engine. Best way to learn is to ask so I did. Thanks folks

The I manifold is more round then the Eta manifold. If your Eta has the same manifold, it doesn't mean the last guy was a fuck up. It's a pretty popular modification to put an I manifold on an Eta engine.

I meant to type "wasn't". and thanks for the clarification, makes me feel better ab out my car.

I've done this on both of my eta engines in the past, and combined with a 325i throttle body, (and if you're really ambitious, port-match the head to the intake inlets), it makes for a very nice intake upgrade.

O'rly, I don't understand the intake upgrade at all. the ETA is built for torque as well as a shorter intake runner, you add a longer runner which takes away a bit of torque to try to add where the high RPM's aren't avail. to me it seems totally wrong. the throttle body I could totally understand.

Makes sense if you change to a 325i cam though.
