E30 M42 swap infomation

[rix313]

Nope.

[blademankiller]

ok next one
i am useing a m42 engine from a e36 and my old gearbox from my 318i engine i my e30 wot clutch do i have to use do i get a 318i clutch or a 318is clutch and if i get a 318is e36 clutch or a 318is e30 clutch will it fit my old gearbox...hellp i do not know wot dto do hear...:cry cry

will i hope you get wot i am geting at

The E30 318i and 318iS clutch are the same. I just bought a new LUK (OEM) one from GSF for about £80. It will come with the pressure plate, friction plate and a new release bearing.

The E36 M42 flywheel is identical to an E30 M42 one so you won't have a problem there. I'd let somebody back this up though as I've never taken the flywheel off an E36 and compared it.

ok nice one

[blademankiller]

will that is all good but i did not get wot i need from there...............
a yes or a no wood of bin better


simon

[MrWhite]

Yes. Does that answer your question better?

[blademankiller]

lol nice one that is wot i am lookin for

nice one..

hi all need some help hear...

If you plan on fitting an E36 M42 you need to change the inlet manifold to the E30 one (E30 one is better than the E36 one any way), you will also need an E30 M42 sump (upper and lower) and engine mounts.

y do you have to use a e30 m42 inlet manifold can i not use the e36 m42 inlet manifold on the engine it will be going in my e30

[Mikede]

The engine sits further back in the E36 so the sump is different. On the E36, the resevoir is at the back as opposed to the E30 which has it at front. This causes it to smack the sub frame.

Nevermind....found it.

Has anyone successfully mated the E36 M42 loom w/ an e30 318i loom??

[kura2]

Hi, if i'm converting from m20b20 l-jet, what else do i need other than the sump? I'll be using megasquirt for engine management.

[Bandit400]

Hi There,
I have just successfully put a e36 m42 into a 316i. The m42 is running the e36 ecu and it has the e36 inlet on. the m42 mounts directly to the 316i box all you have to change is the spigot bearing in the m42 crank.

Any questions about the swop just ask

[XRMike]

Im thinking for doing this conversion. I wanted a 24v engine but its juts too much hassle for me.

If I sourced an M44 1.9 engine with ecu and wiring and EWS etc, I can use my 318i box/fly/clutch/prop/engine mounts etc?

A few things may need to be fiddled with but the rest should be ok shouldn't it? Im hoping to make it pokey and keep the 4 pot handling charateristics.

[rix313]

I'm not sure how you'd get on adapting the M44 engine loom into the E30 car loom, suppose you just need a pin out drawing for the E30 chassis loom and one for the M44 engine loom and then just match the wires as required, if at all. Gearbox should bolt up ok as the block is the same as the M42/M40.

[Andyboy]

If you use an E36 engine, get one made after 9/93. These do away with the timing chain idler gear and replace it with a curved guide rail.

You can use the M40 box, prop and 4.1 diff.

The 318iS box is also found in the M40 engined E34 518i.

[pdgti]

can any one or does anyone know where i can get my 316i e30 converted to the 318is (1.9) e36 engine locol to london???

im new to the e30 thing and any help would be great.

[markgq4]

do you know if the above also counts for the M44 engine?
will it fit the m40 box etc?
engine mounts?
and what sump and pick-up? can i not use the m40 items?

thanks.

[PiLLLe]

Hi.

I've pulled out my V8 and put in is lump, now I can't get engine temperature signal to instrument cluster. Does anyone know how to solve this problem.
I know that i need 1 pin m40 sensor, but is there a place where I can stick it or do i have to fabricate something...

[balilu91]

youve got 2 sensors under the intake manifold near the oil filter. one is blue which signals the ecu. the other one goes to the cluster. if its an e36 engine its coloured black and you need to change it to a brown one from an e30 engine to work with the cluster

[PiLLLe]

So no mods needed thx mate

[PiLLLe]

I've changed the black to brown one, it took me like 3 hours and tones of nerves and it still refuses to work. Is it possible because I have inst. cluster that was originaly from m10 engine?

btw the black one is two pin and brown single pin

[balilu91]

Yes it is possible, you should try an M10 temp sensor and see if it fits.. They may have different a thread...

[redcar]

You need the throttle clip thing from a 318is also

I tried an M10 cluster on an M40 engine (troubleshooting SI fault) and the temp gauge tried to go backwards so you might need to change the cluster out.

[PiLLLe]

I've changed the cluster and now it's all working. Temp gauge, fuel gauge tacho all, all I've got is a minor problem with twitching of the gauges, probalby just lose ground somewhere.

So facts to note m10 cluster will not work on m40/42 engine

[vokietis]

Any chance to bolt m10 box onto m42???

[PiLLLe]

As far as I know no. Only if you make an adapter plate.

[johnl320]

Any chance to bolt m10 box onto m42???

No, you need an M40 or M42 box for a direct fit

[vokietis]

ok,can i use 1984 320i box ,prop,flywheel and clutch?

[rix313]

The gearing won't be right so you would need to look at changing the diff. You would use the clutch and flywheel with the M42 box but you need to fit the gear from the M20 starte to the M42 starter and also neeed to change the release bearing too rom what I've heard.

I have a couple of M40 boxes that you could use if interested.

[Roysneon]

So how much modification does the M42 exhaust manifold require to clear the steering shaft? I'm having a hard time sourcing an E30 one, but I found one from a 318ti.

[rix313]

None at all if you have a standard E30 rack. Check your engine mounts aren't buggere as this could cause the engine to lean over and cause problems. If you have an E36 or E46 rack fitted you may need to have to engineer something, Danthe makes steering shafts that could help here if you are using a later rack

[Roysneon]

Great, thank for the tip. I should have said E36 exhaust mani in my post above. I have a right hand drive touring here in Canada that was imported so all the M42's here have lhd exhaust manifolds and would interfere with the steering.

So if a rhd E36 manifold will work in my rhd E30 with M42 swap I'm all set.

[rix313]

Ah right! Couple of things to note. The E36 engine sits further back so there is a chance the E36 RHD manifold may route slightly differently to an E30 manifold and cause potential issues. You will also need an E30 M42/M40 sump to fit it into the E30

[Roysneon]

Yep, I've got a full E30 M42, just need that stupid exhaust manifold now. Will likely cost me more to get that than the engine itself.
