Parts needed for Super ETA to 2.7L conversion?

[e30Prestige]

I'm not usually one to make a thread because I am pretty good with the search button, however, there seems to be many different opinions when it comes to this build.

I have researched strictlyeta, various build threads and have messaged countless people who have done the same conversion. What I seem to be finding is that many parts differed from person to person depending on their personal goals. I also found that the parts required are different between years. Being that I have an 88' 325, I know i need far less than a person with say a 1986 325es.
So I would like to know for myself and anyone else with an 88' SETA looking to do this swap which parts I need from a 325i/is.

I know I need at least the following parts: (correct me if I'm wrong)
-885 head preferably with "I" cam
-"I" throttle body
-"I" intake manifold??
-173 ecu with chip of my choice

Will I need anything else to get this project going? Some people recommend the double valved springs from an "I" head which I will probably do but i know it's not a MUST right away for a non-turbo application.

Thanks in advance!!

If you've read strictlyeta then you should be in good shape. Also be aware the supereta 885 head doesn't have some of the oiling that the i 885 head has.

As far as what you "HAVE To" do, it really depends. I for one wouldn't pass up the opportunity to rebuild the head (pressure test, valve job, guide sizing, etc.). Can't tell you the number of times I get calls from guys who slap some parts together only to have something easily replaceable fail (%90 of the time you'll never hear about it on the message board).

also there isn't much point if you dont use the I-cam which by the way needs the double valve springs.

I plan on refreshing everything with new gaskets, port and polish, and a leak and pressure test. All that stuff is a no brainer. I'm more concerned with what parts are coming from an "i" car. For example, I've seen people who are using m50 injectors or #19 injectors and an AFM from a 325i. Are those parts a must, upgrade, or for people who don't have a supereta? The problem with strictlyeta is that he explains everything from a 1986 325 standpoint and as I understand it needs more parts than an 88 would.

This is likely the case but not always the case. I used the 885 head that was on my seta. It DID have all 7 oil passages drilled. I cannibalized a junk " i" 885 for cam and springs.
I used:
My seta 885 head.
"i" cam
The i dual valve spring. No sense doin the swap if u can revlimit it. I believe the seta spring may float at rpm.
Refreshed the head.
I intake
I tb
173 ecu
Green top inj- I would say not needed, but why not. The pintle design is way better.
Initially I didn't have an i afm- it did run fine on the seta afm. But later I found an i afm and used that. No noticeable difference.

I think that's about it... If I think of more I'll add. Do it! It's well worth it.
