Lee Parkes' E30 Alpina B10.

[leeparkes]

*Update*

Picked this up yesterday

3.73 slipper.





Cant wait to get it on because trying to control an M30 with a 3.64 open diff is a pain in the arse,especially traffic light grand prix.
Ive got a bit of time to paint it up and i think im going with the same theme as the engine (hammered black case and silver back plate)
ive got to get all the oil off the back first as it has no speedo sensor and when i was maneuvering it about it all p1ssed out the back,all over the slabs too bloody stinks as well.

I was originally looking for a 3.91 because all i use the car for is built up area driving where a short diff is ideal for short bursts of acceleration, but i think a 3.91 would be a bit too short so im well pleased ive got a 3.73!

Whoop Whoop, cant wait

Let the fun begin

[blackcountrybimmerman]

Wire brush, hammerite.....sweet as.

I'll pop round the weekend mate.

Todays antics

Wire brush, hammerite.....sweet as.

I spent about 3 hours chipping 20 years of rust off then wire brush on a drill then the Dremel came out to get to the awkard bits,it seemed to take forever and not a nice job to do,i can safely say this is the first diff ive dressed up and the last!

then i gave it a once over with hammerite (black & silver)

Few pics, oh and an Alpina rep makes an excellent diff stand










Jobs left to do, paint the back plate bolts black,put a new bush in then put fresh oil in the throw it on the car and go snaking


Oh and this is the oil that drained out the diff,it looks as old as the diff itself



I was told the diff came off a 70k auto so fingers crossed its fine

[wullie325i]

that diff oil is black as lol it must have been stinking as the last diff oil change i did made my eyes water

on a plus side at least it had oil in it as i have had many a e30 diff with nothing left in them or next to nothing.

[blackcountrybimmerman]

Where did you get the diff oil from in the end?

[leeparkes]

Havent got the oil for it yet, btw the key you lent me didnt fit the drain plug, tipped my tool box upside down and dug out a 10mm allen key which fit perfectly.

Anyone know what size the driveshaft allen bolts are? and do they have a tendency to snap?

Sorry about that kidda.....

They must have different sized drain plugs.

Lol, no worrys ill drop it back off to you, cheers.

from memory, they're M10 bolts with 8mm hex key fitment. some of them have those odd female torqs bolt heads, like some bellhousing bolts have.
i've never snapped any.
remember to loosen the prop and all driveshaft bolts before removing things, it's a tad hard otherwise a helper here will save ages if you can get someone to operate the handbrake while you loosen them. saves lot of crawling in/out

[leeparkes]

if you can get someone to operate the handbrake while you loosen them. saves lot of crawling in/out

Looks like a job for the wife then

that's the spirit. you do the handbrake and send her underneath to do the bolts

Todays action




I decided today to get the car in the air to remove the 3.64 open diff, the plan was to get my diff off then put the slipper on in the morning, started at 1:30 and the diff was off within an hour, German build quality strikes again as every nut & bolt came undone without a fight, anyway i was on a roll so i decided the slipper was going on today


Filled it up with nearly two litres of this stuff





Then popped one of these in





And at 4pm hey presto!





The only problem i came across was balancing the diff on the trolley jack while lifting it up to the body but after a bit of wrestling it was on.
Dropped the car back down and went for a spin (literally) i brought the diff with no knowledge of its condition but it was very cheap, well i was surprised when it didnt whine and it locks up as it should,
so its safe to say its a 'good-un'

As ive gone 3.64 to 3.73 i cant really tell the difference between the two apart from it feels like it pulls a little bit better in third


Well with that done ive got to do it all again because this 3.64 vvv





Will be going in this vvv

My new project, BMW Compact 318ti sport individual.








For what ive got planed for it the original small case diff wont cope

[Rav335uk]

No difference noticed???
Should be slightly better on acceleration surely?

[DRIFTBOY]

3.64 - 3.73 is only about 2.5% difference in gearing, so probably not a dramatic difference!

[leeparkes]

First and second are so frantic anyway i havent really noticed but it feels like it pulls better/quicker in third

Get that 3.91 on your cab Rav, what profile tyres you running on your alpina's?

[Rav335uk]

3.91 will be a juice guzzler.
Tyres are 205/50/16's

[leeparkes]

3.91 will be a juice guzzler.
Tyres are 205/50/16's

Wont be that bad because you have a large rolling radius on your wheels

I noticed a difference when i went from 16's to 15's.

[Rav335uk]

Might give it a go, if I don't like it, i'll take it off.

[PazzaAE86]

Will report on what a 4.1 feels like tomorrow once ive finished a few jobs on the owd E30. I think it'll be mint hahahah!

[Rav335uk]

Forget using 1st then, it'll rev like fook and go nowhere
And is it a small case diff?

[PazzaAE86]

Yeah its just the stock 318iS diff. I'll use it till it fails and then swap it out for a medium case.

[leeparkes]

As rav said 1st will be useless but it WILL be fun

Weld it up and do donuts in 3rd!

Join the AA for when it twists the guts out of it, when gareths went he couldnt move the car

Have fun

[Rav335uk]

I would change it now, when that thing goes, it'll explode.
Ask Gareth, his M30 completely killed his small case diff, and i do mean "KILL"

The easiest to do is M52 but i have been considering S50. not sure yet


Nothing wrong with a bit of subtle councilness

[PazzaAE86]

4.1 is awesome.

[zaust]

I find 1st useless with my 64 which is why i'm going to the 46, can't imagin what it's like with even shorter leg's. what gear box is it ??

[PazzaAE86]

We're not really sure what gearbox it is, as discussed in the linkage thread, as my 325i linkage is about 2 inches further back than the usual..

[leeparkes]

4.1 is awesome.

Has it locked up yet Bet its fun.


Btw, ive added a Civic type R to my kill list

Im loving better traction off the line with the slipper, it makes the M30 even more enjoyable

Did you beat it by some distance???
I've had one of those on a damp road and beat it, just, to much slip.

[leeparkes]

It was a fairly dry road, we were neck & neck off the mark but once i got into third i started creeping away from him then we got to the next set of lights and he turned off
I launched in first too so maybe if id gone for it in second i might of dealt with him quicker.

not something the type-r owner could say
