How to make a 318 into a 327i

[Mike325]

Nice work. Seems like a nice alternitive to an m50 swap. Makes it a lot eaisier to get some nice power. So, let me get this strait. SETA bottom end, m20b25 intake,head,wiring harness and comp? Sorry, we all seem to be a little slow on this.

^^ haha.. nah man... hes got a regular ETA engine (84-87) in there at the moment with the I intake, cam cover and engine management system right now. THEN later hes gonna swap his old cyl head from his current car over, which is also pretty much an ETA head but beefed to hell with a wicked cam, a bit of porting, the decent I valve springs etc....

Man, I want that front end! It's an 84 with plastic bumper or is it a tucked and painted stock bumper with valance?

Its an 89+ bumper painted black with the valance and IS lip.

Ah, ok thank you sir. I was under the impression that you could not switch the I head and intake over to an E block. Did he change the wiring harness or just get an ecu for an I model?

Its an I harness and ecu spliced into the older square plug with a round plug.
