Super Eta upgrade

[E30Hooligan]

to see your results hit the pavement you need to swap out your 2.93 diff and put in a 3.73 (lsd's are nice), you also want to change from a dual to a single mass flywheel, this is lighter and allows the engine to rev up faster.

The SETA m20b27 and your regular m20b25 actually use the same head casting, HOWEVER the typical 'i' head has extra oil holes drilled in it and of course comes with a different cam/ dual valve springs etc.

The seta has the 885 head, you do not need to change it out. You do need everything else.

^...and FPR, vaccuum hoses for the new boot, and the throttle body.

Forgot FPR but don't need that vacuum hose depending on what boot you get. Also I already mention throttle body.

Omg so much wrong info. What is needed is 885 head with double valve springs and I cam, late model ICV, I intake manifold, 173 DME, I Throttle Body and intake boot.

Yeah, I'm with Rigmaster on this one. I'm pretty sure the SETA's had the same wiring harness as the I's, so it should be pretty much plug and play. Check http://www.strictlyeta.net/technical/328i_1.html, he has an extensive article covering these types of modifications, that should answer all your questions.

[Rigmaster]

No, you need the "i" harness also. Don't forget about the "i" plug wires too.

you sure about that?

I'm fairly sure the super eta and the i stuff is the same here.......


about 99% sure.........

So i have to bond my car cables to a "I" harnes?? is that it?, and what else?, my bad im just confused...

Another doubt is if the 327i upgrade will need the "I" ecu harness in order to work or I just plug and play the "I" ecu? thanks in advance

[KenC]

You should upgrade the injectors to at least 19#

[reztat]

ohh ok i have wonder if that should be necessary but is ok, it sound great!...Another question if anybody knows the answer, I have a friend with a 86 eta, his car runs great but he want's to know what parts are interchangeable to gave more punch, for example what would happen if he put a "i" computer and more things like that....

[kingston]

I neglected to mention that you also need the FPR (Fuel Pressure Regulator) and the AFM (Air Fuel Meter?) for the conversion.
