The m30 engine bay thread.

[Jean]

I never use them, but I've been thinking about picking up an e23/e32/e34 tank to see how it fits.

Should be something like this:




BTW, the stock e32/e34 ecu/dme/relay box does not fit w/o modifications in the front right corner... i was hoping it would so I can keep the dme and relays there but I'll have to modify it.

Why the in bay ecu?
Good idea on the ammo box.

the harness had to be stretched beyond what I was comfortable with to fit inside the cabin. This is the easiest place to put it and it's in a waterproof box.

I agree, though Once I finally got it through the fire wall I fitted the ecu in place with some flimsy brackets and cable ties.

Looks great!

On a side note, it's good to see my thread going lol!

Any new m30e30 owners wanting to contribute?

Build thread in Sig. I still need to spend the time to tidy up all the random wires and remove all the I'd tags on the wires

I've been lurking here for a while so thought I'd contribute :) (normally I'm on ECCA Doughnut). My car is a daily drive, so it's not the prettiest thing going, but it's been really reliable for a year now. A few specs: cirrusblau 4 door, 1988 320i with M30B35, e30.de type 2 mounts, modified M20 loom, 318i single mass flywheel, Australian Clutch Service Xtreme organic clutch & HD pressure plate, G240 gearbox (yes - it's lasted 10,000km so far, no dramas), 3.73 diff.

Just went to the carport and snapped the pic.

Almost ready to start up for first time. It's a very low mileage m30b35 so I didn't mess with cleaning up any of the finishes. I like the aged aluminum.

Coupled to an 4hp22 just for grins and traffic.

Cheers for the contribution lukeADE335i, interesting flywheel/clutch and gearbox choice.

Be sure to chase the front cover for your spark plug wires (it does fit), I bought one new from the dealer for around $35! But I'm sure you can find one at your junk yard, just keep an eye out - really neatens the engine bay up!

n3nyongmini, you went with the auto huh?! Nice work with the e34 coolant bottle too!

Keep them coming lads!

[lukeADE335i]

Thanks Doughnut - since doing the swap, I managed to source a G260/5 with e28 single mass flywheel & 240mm clutch, so if the G240 eventually dies (or the clutch wears out) I'll go over to a more conventional setup. So far it has been all good.

My latest...crappy cell pics

Yes - I know the bay looks like crap but we have to keep it that way for Lemons and Chumps. Yes - I know it's a b34 (had 4 laying around the shop) but what you don't see is a new fully ported head, b35 cam, complete engine rebuild, scraper/windage tray, Miller War Chip and MAF.
When the car was on the dyno we used the factory m20 air box after the 4 pull we finally saw the intake hose collapsing so we upped to a larger K/N cone - much better results.
The theme is Max Mad so that's why the blower scoop

Oh man... SHAKER FTW!

This is an updated picture of the engine bay on my e30 (see 1st post) before I sold it two years ago. You can see I fine tuned the intake setup slightly.



Christ I regret selling that car...

[navytapaul]

This is mine, haven't had a chance to rewrap the harness yet, and still doing some tweaking. Hoping to acquire an e28 radiator soon.
