Got my engine and trans today!!!!

Since we're all sharing a bit here:



Welcome to m30 club!

George how did you extend the wires? Could I just use a heat shrink solder sleeve? I read somewhere that you can unwrap the injector wire and re wrap it and it will reach

[Andy.B]

The m20 1.1 harness can be used on an m30 by cutting the sheath of the harness, routing and positioning the wires where they need to go, and then wrapping everything again.

I used the re route approach on my fiances 87 325 and only cut and spliced a single wire that was incredibly tangled up in the harness.

Ok sounds good! A little horrifying (wiring scares the crap out of me) but I'll see what I can do!

I personally found it tons easier to just use a b35 harness and a 173 dme. I first bought a m20 harness to do it when I got it I didn't like how it layed out over the motor so I sold it and grabbed a b35 harness.

Yea I'm looking for the easiest option right now I'm trying to do the swap in a week or less

Un-wrap? That's new to me - but there is so much back and forth, twists and turns in a harness when they make them, wouldn't surprise me. I bet you have a friend that know how to solder - buy him a 12 pack of naught light. My 2 cents on that. PS - don't use those "heat shrink solder sleeves", how will you know if you have a good joint is you can't see it?

Oh yes. Very true - I used it(the m20 harness) cause we assumed the m30 harness was messed up. Turned out to be a bad crank position sensor. Oh, and if your harness came form an auto, you have to trick it into thinking it's in park for it to start.

Not going to happen. Not unless you have everything lined up like drive shafts, rad hoses, tranny mounts, oil pan, etc...

Plus, you'll have little details like mounting radiators (assuming your not using the m20 rad - the bottem outlet is in the wrong place.) relays, fuel lines, exhaust....Best of luck!

[lukeADE335i]

If you're going for the e28 535i radiator the mounts are easy - just a couple of pieces of right angle at the bottom of the radiator & bolt the rubber mounts through, top bolts right up as the 325e used a radiator with the same mounting style as the 535i.

I unwrapped and then re-wrapped my loom - worked fine. Had to lengthen two injector wires only (this was with a Motronic 1.3 harness, but the 1.1 would be the same for all intents and purposes). Remember for the B35 you want the e34 179 DME (some mention of using the 325i 173 DME - does that work??).

Looks scary but isn't that hard if you are patient with it:



Re-wrap, then stuff it all into the e34 plastics (+ some e30 M3 bits) and you get this:

Yep I have everything lined up engine and trans mounts are in the mail swapping the output flange on the transmission and mishimoto e36 radiator is also in the mail everything else bolts right up

^Nice. Someone's done their homework. ;)

[afelice]

Thank you George! This is by far the biggest project I've tackled before but I am very confident I have a few people to help me and I am very optimistic that I can get it done in my time goal!

Return the clutch and start saving for a different setup. I went the stock route, 5 years and ~12k miles later my clutch is starting to somewhat slip when I try to up the rpms shifting from 2nd to 3rd and 3rd to 4th.

Unfortunutly I don't have time for that
