m30 swap, what's missing?

[///Maddog9000]

So I just picked up a m30b34 setup from another member here on the forum. I haven't picked up the longblock and trans yet but, I have all the other goodies at hand. I have a few questions about the stuff I don't have yet. Supposedly, it has Shrick 282 cam, 24#ers and a MarkD chip. I guess we will find out soon... not to doubt but, you know the story...

Original FS thead: http://e30tech.com/forum/showthread.php?t=37536

What I have:

'86 635 m30b34 and g260-6 trans...?? I think...
wiring harness
Flex-Lite fan
e28 radiator
eta front DS and e28?? rear... can't remember but, was told its the right setup
300mm.de mounts
b35 exhaust manifold and downpipes
ecu... can't remember the #
power steering pump (looks like the one Frank said to use)
misc. goodies (plugs+wires, filters, belts, etc...)
possibly some other stuff I'm forgetting about

What I know I need:
motor and trans mount rubber or poly
trans cross member
coolant hoses

So, what else do I need? I'm pretty dumb when it comes to wiring so I'm hoping from the pinout diagarms my buddy can wire it up. Should I try to squeeze it into position 3? I was reading that you only need "4-6 cm" of room at the back of the head.

Any advise on the whole process would be appreciated.

I have done alot of searching and reading but, I don't have very much time and often read conflicting info!

Any m30 swaps in Metro Atlanta? -call me (678) 697-8409

That's a good solid engine, Terry re-ringed it and put new bearings in also. I know he was planning on boosting it.

[jim325]

Pretty sure the rear portion of the driveshaft has to be E30, or fit a small case diff. I think the e28's used medium and large but don't quote me. Where you put the engine will most likley determine the length of the driveshaft required.

The M30 is heavier than the M20, I think it's like 60-100lbs? Don't quote me. Personally, I bought AKG poly trans and motor mounts for my swap.

ECU should be 059 from that... I think. Atleast that's the ECU number for an 86 535i, 635 might use Motronic 1.3 in which case I have no clue on ECU number.

Theres what, like 2-3" or so of clearance between the distributor cap and e28 radiator depending on engine position. The slimmer the fan the better off you are, assuming it is big enough to cool the motor.

I didn't notice where or if you had gotten an e34 535i oil pan and pump to clear the steering rack. But if you didn't you'll need one inless you wanna call up Japandrew and ask him how he cut up his subframe..... That's a joke.

Trans crossmember can be used from your 3 series, assuming it's an M20 motor. M42 motors and M10(I think) used different tranny braces and will not work.

I think you can use the e28 hoses, but you might have to experiment with that. If you asked these questions a month or so later I might have better answers.

Good luck!

Otis,

I've been trying to contact Terry about the motor. I tried e30tech PM and a email I found listed on a FS thread. Any info on the motor would greatly help. I was planning to refresh all the gaskets and seals but, if he did then I won't waste the money or time. I know the block is tapped for an oil return line. I'm thinking about getting the motor in and see how it feels before putting any boost on it. Sooner or later I will be commissioning a b34 manifold...

Jim,

yep, 100ish lbs heavier! 059 is correct for the ecu I have. Supposed to have a MarkD in it. I might open it this weekend. Already have a e34 pan/pump installed. PO has the other half os the DS and said its what I need. I'll see when I get it. longblock, trans and DS half is still in Charlotte, NC. The Marine Corps sucks every second they can outta me and I have no time for fun!

thanks for the advise guys, I was already looking at AKG poly mounts so thats a go.

Someone sell me a e30m3 trans brace!!

haha, silly Japandew... who does 'things the right way, anyway?'

Anyone know about the Miller MAF setups? I don't have an AFM or MAF yet. I would assume the MAF setup would do better for forced FI and probably NA too. What do you guys run?

[dannyyisntt]

^ I'm interested in this too

[///Maddog9000]

The way I see it is, for the price of a Miller MAF and a WAR Chip you could go MS II and be done with it. I'm not very savy with standalones but, everything I hear about MS is outstanding.

I wonder if you can program the chip that comes with the MAF setup or do you need a WAR Chip?

I'm looking for the best setup to support 10-15psi for a daily driver. At the same time I want something simple but, multi-tunes are very helpful.

[quickervicar]

I am no expert, but IIRC from my E34 research you cannot program the MAF setup without the WAR chip upgrade.

[jim325]

I have a MAF from them with chip, no WAR chip just there standar MAF and chip deal, in my M20 N/A and I like it. I was also going to go with a Miller MAF+WAR chip for my B34 turbo swap but after doing some research and such I decided to go MS. I had Peter Florance over at pftuning build me a PnP unit. Should be getting it within a few weeks. He offers tuning help and will help get it up an running. Great guy.

Have you tried emailing Brody at Miller to see if you can just flash there chip with a tune? Although that would probably be more difficult than just getting the WAR chip. You probably could but might wanna thro that kinda question in an engine management type section of this forum.

[ldsbeaker]

I've been thinking about this as well, but honestly, I'm going to do the M30 swap first, make sure it runs okay, THEN get the Miller MAF and Chip.

[Zacm829]

I was looking at this setup for sale too, I'm sure you got a good deal.

What year car is the swap going into?

When I swapped my b34 into my late model car, I was advised to
convert the engine to Motronic 1.3 so I could simply use my exsisting
harness and just have to extent some injector wiring. The conversion
was rather simply as well. You need the toothed timing wheel off a b35,
the CPS and ecu. I believe that was it maybe missing a couple things.

I'm semi local in Columbia if you have any questions pm me for my number.

Good Luck!

So, I bought a e30 m3 trans brace from Ron-Man. By the way, BMW has two left NIB in the whole country! They are cheap at $37.xx each! Anyway, I was about to order a set of AKG motor and trans poly mounts.

I decided to start some research on Bosch Motronic 1.1/1.3 It seems like it is better to convert my motor's wiring to the b35 harness and add whatever extras it takes to run the 1.3 system. From what I read it's just a smarter, better running system and from what I can figure, connects to my '89 chassis better.

Final goal: Motronic 1.3, Miller 3.5" MAF and WAR Chip tuned for Shrick 282 and 24lbs. injectors.

Anyone converted their b34 to b35 electronics? I'm still not totally sure what all I need to make the change.

[quickervicar]

I've been thinking about this as well, but honestly, I'm going to do the M30 swap first, make sure it runs okay, THEN get the Miller MAF and Chip.

My thoughts exactly.

[///Maddog9000]

The only problem is that I have no provisions for intake mass... I guess I could get a junkyard AFM just to get it running.

I'm planning to get the Miller setup and tune it for the cam/injectors/maf from the get-go. I have the time so why rush it?

[CorvallisBMW]

I have the Miller MAF/WAR on my m30 and love it. Really helps wake up the engine, especially when combined with a lightweight flywheel.
