Engine + Driveline / Performance Ignition Leads

« on: May 10, 2009, 01:08:33 PM »

I have tried Magnecor plug wires, and I was really impressed/satisfied with the results. they were not cheap, but very good investment.
they were 8.5mm, part number 45314. Ģ90.70

Engine + Driveline / throttle bodies

I think the best set of TBs to fit on M42s are the M3 E36 3.0L
Almost straight fit, very little modification needed. And same spacing between cylinders in the M3 as in the M42.
Besides, much cheaper than other systems

which m47 crank are you talking about when your making your calculations?

Me? M47 88mm

if you use S50 pistons(86mm) instead of S52 you get 1952cc.
4 S52 pistons with 45,000kms on ebay:

Swaps, Turbos, Buildups / m42 head/m40 block

« on: April 22, 2009, 03:54:02 AM »

Yes it can be done, Iīve done a few already.
Blocks are exactly the same, M40 has oil squirters.
you have to swap everything else from the M42, even the crank.
Right now I have 10,000kms on my M40 engine with M42 block (converted M42 into M40)

Bunta, if you use S52 pistons(86,4mm) and M47 crank with 135mm rods(stock S52 rods), you shave the pistons to leave them 3mm below deck(you would have to shave about 1-2mm) you would end up with 2064cc, and 8,5:1CR.
Bearings have the same size between S52 and M42 and M47.
head gasket? stock M44 86mm bore.

Ivan petrov, you would have 1862cc, but you would need to shave the pistons, because M44 crank would leave the piston 1,5mm above deck, this would destroy the head, piston, rod, or all of them... you need to have the piston 0,15mm above deck maximum.with 0,15mm above deck, CR would be 10,3:1

I have two spare S52 pistons... they come from a blown engine as well, but they can be used, 22mm piston pin. 86.4mm bore.

I have a complete spare M42 E30 engine harness with ECU, I could sell it to you if you like, along with other parts you might need for your project.
The harness is in perfect working condition and has been used by me. The only problem is that I live in Barcelona, Spain, So shipping might take a little longer as well as a little pricey.

Ok, lets see if we can get this straight finally:
- The gearbox on M40 is exactly the same as in M42 cars. So m42 engine bolts right up to M40 gearbox.
-when you are trying to drop an E36 M42 into an E30 chassis, from the E36 engine you only use the block(with crank rods and pistons), and complete cylinder head.
- The cylinder head cover is exactly the same on E30 and E36 m42s. The one on M44 is different.
-Everything else needs to come from an E30 M42: FULL intake manifold, FULL engine harness including ECU, Oil pan, and pulleys if want to go faster(A/c on E36 has different belt, also Power steering pulley).

I have both wiring looms from E36 M42 and E30 m42 side by side and the plug for the ECU is exactly the same on both.
Now, I doubt plugging the E36 ECU into the E30 or viceversa would work, because the E30 loom does not have knock sensors, electric vacuum valves, and the E30 has different ignition coils than the E36

To go trouble free, just drop the E36 M42 block and cylinder head into the E30 chassis and get a complete E30 M42 harness and all the other parts.

By the way, the engineīs supporting brackets(the parts that bolt to the block and engine mounts, are different, so you need the ones from an E30 (The M40 ones work good).

Swaps, Turbos, Buildups / Intake swap e36 to e30

« on: December 01, 2008, 04:44:10 AM »

Thanks for the info. In my country doesnt have m42 wiring harness for e30 so i have to use a e36 wiring harness do you have any idea bout that. And also my engine is from a auto e36 so did the DME link with the gearbox?

As far as I can tell, the E36 harness is not a direct fit(I would say it wont work...)The E30 does not have knock sensors, the E36 has electric valves for vacuum operated intake and the E30 doesnīt.

Like said above, NO, you can not use the M40 wiring for an M42. Basically because aside from the block, itīs a completely different engine... 8Valves/16Valves...
The M42 engine(E30 or E36) can only go into the E30 chassis with the E30 M42 wiring harness.

Anyone has the wiring diagram from e36 engine to e30 engine.

Dude just read above:
You need to swap the entire engine wiring when dropping an e36 engine into an e30 chassis...
That means there is no wiring from e36 to e30, you just use the whole e30 engine harness...

Swaps, Turbos, Buildups / Dreamtuning: max stroke crankshaft that it will fit...

« on: November 19, 2008, 04:30:24 AM »

I have compared the M47N crank (90mm stroke) and M47 crank (88mm stroke)
The M47N used different crankshaft bearing dimension
I've checked the ETK, using the part use facility and it turned out that M47 crank and M42 (also M43, M40 and M44) using similar crankshaft bearing
I don't know if we can machined the block to accept the M47N crank, but it's too risky I guess

Guys according to reaolem.com, the crank bearing of the M47N crank is 60mm, the same as the M42 and M47.
what I meant by risky is that the front nose of the M47N crank is way too short, so a custom adapter has to be made to extend the nose,this would result in a two-piece crank, I would not trust a two-piece crank(especially with the chain sprocket beign in the extra piece)at 8000rpm...
The guys at MM say itīs ok with their adapter, ok, go for it...

thanks pungky29 for the post about the hartge and its steel plate
I had a magazine of those years with an article about that hartge engine but I can't find it and at the time I wasn't really interested in engine internal mods
 
@hesgone2fast, as I wrote on title this is only dreamtuning, no one man here will do what there is in this post, as it's unrealiable, difficult, pricey.... it was just curiosity
...you made a mistake with the oversquare/undersquare thing in your post

Donīt say no one will ever do whatīs on this post, Iīve spent $5000 on my engine, I built it myself, Iīve spent 3 years collecting parts,gathering info,I bought  an M47N crank and saw it was too risky to make it work, so I sold it...
What mistake did I make??

hey guys, like said above, you wouldnīt want to go much more than 88mm stroke on this engine, maximum bore is about 87mm.
You could use the M47N crank (90mm) but requires some mods to it, and adding a custom front nose in two pieces (not very reliable).
more than that, it would be too much over square.
Stock M42 rods can be used with M47 crank with no mods. but the piston would have to be shaved until desired compression.
By the way, Tonight I will put my M47 crank(88mm) for sale up here... I live in Spain, so Itīs a great opportunity for getting one in europe, as thereīs no other for sale anywhere.
