2. e28 radiator
3. e34 throttle cable
4. m20 temp. sensor ( not sure on this )
5. manual box , clutch and flywheel
6. e36 328 prop

the engine loom i have is from auto will this have any changes to the swap?

Why E34 sump, if it's an M30 it should have the same sump as the E34?
M20 temp switch, Yes

[johnl320]

Rav, it will have the deeper sump also fitted to the e28.

It also has the coolant pipe on the back of the head that will require the e32/34 blanking plate.

There are lots of different radiators used, e30 325i, e24 635i, e28 m353i, e34 535i are some that have been used as far as I know.

I'm using an M10 throttle cable

M20 temp sensor for the gauge is required.

dependant on which gearbox you go for depends on what prop you need. I'm using M10 gearbox with a prefacelift 325 prop.

Hope this helps

i think i read that a e34 sump was different to that of a e24 635 or e28 535
if i am wrong then thats great i can tick it off my list thanks rav was there anything i missed?

[Andy325i]

I have a 328i prop if you need it

[k20trew]

thanks for the help johnl320
are there any wiring diffrences i should be aware of?

[johnl320]

You need the e34/e32 sump I'm afraid

[k20trew]

how much for the prop andy? also i am in s.wales how far away are you

[leeparkes]

You will also need some mounts not sure if mine fit earlier engines though, can anyone confirm?

John, was yours an early engine?

iirc earlier pre cat engines had more poke

[k20trew]

thanks lee if we can confirm your mounts [pos.3 if i am correct] will fit my 1984 635 csi motor. i will be having a set off you. your thread is awesome nice car mate

No mine is from an 1987 e32, I did have an early e28 lump buts it was a bit ropey.

Dude Jon is right, my cock up, it will be running the old M30, not the later one.
Lee ,the mounts are different, looking at E30.de.

[leeparkes]

Looks like the inlet ones the same but the exhaust side bolts in the middle of the block

if the inlet is the same i could supply you with just that side, then fit it and lift the engine level (sump & crossmember) then get the exhaust side made up DIY

[k20trew]

so i would best get mounts from e30.de for my early m30

[leeparkes]

179 euro's, and is that plus post?

Up to you really, to make the other mount you can use wood to make a pattern then take it to a machine shop to get it made out of steel ,maybe cost you £50

[k20trew]

just done some research on e30.de and wiki regarding my 1984 635 csi motor and i read some engines with a cat ,had a 8.1 compression ratio and only made 185 hp a 33bhp loss but the pre cat cars still ran with a higher compression and the usual 220ish hp
wiki says these lesser power cars were USA models
how do i determine if i just bought a crap 185hp m30

[johnl320]

If you have a 1984 m30, it will be the early type making good Hp if its not totally shagged

[k20trew]

thats a releaf but aside from having a cat are ther any other ways i can determine if i have a lesser power m30

[johnl320]

I think my E28 had the distributor mounted on the side of the engine block, newer versions of the m30 had the distributor (cap) mounted at the front of the head.

[leeparkes]

iirc the lesser powered engines are the ones with the different shaped inlet manifolds

Got any pics Lee? What have I got then? from an 1987 e32??

[leeparkes]

Havent got a pic but there from around early 80's, yours isnt one and im guessing K20trew's isnt either

[shedrool83]

I have a e34 m30 sump and oil pick up if your needing them.

[k20trew]

how much for the sump and pick up shedrool posted to s.wales ?

Pm'ed

[Rav335uk]

Here's a E32 3.5, looks the same as mine.


And this is an E28 M30

[leeparkes]

You got a pic of a 'really' early M30 Rav

[Rav335uk]

Ofcourse Lee.
This?


Or this?

[leeparkes]

Thats the one

[Rav335uk]

That's the E12 m30, never seen one in an E28.

[e21Jason]

Early 635 based on a e12 had that engine how much did you pay as I need a few bits of one of one of those do you have the rest of the car

a better option would be to get a e34m30 and sell tahr engine, that ones runs ljet so the wiring is not as easy and you need a e28/24 manual box to take the flywheel sensors for the Ecu

[k20trew]

sorry e21jason i dont have a complete car, i am buying the engine and bits out of a 1984 e24 635csi
i asked leeparks if he could take a look for me and he told me it wasnt the lesser power m30

[k20trew]

thanks for the pics rav
in the over head pic of the e12 m30 [white car] is this the lesser power m30 with a m20 style inlet that lee spoke of earlier

[Rav335uk]

Well according to the WIKI, it has the same power as the E34 mo30

[k20trew]

can anyone shed any light on mounting differences between early and later m30s i had no idea they were different unit i went on e30.de and is this goin to cause steering knuckle and manifold clearence issues
