top speed 95mph

[daymo69er]

i think i sort off know the answer to this anyway but just to clarify

i have the m52b28 with the 2.8 gearbox with m50inlet and a danthe remap,

with the 318i diff i be honest of the mark it goes like a shit off the shuvvle but in 5th it will top out at around 95 i believe this is all because of the diff aint it and if i changed it , it would sort this out?

[rich318i]

sounds about right had a 3.91 diff and max was about 120 ish

[daymo69er]

its a nightmare, im just waiting for the engine to chew the diff up, but cruising round in 5th is pretty kool just a nightmare on motorway drives!!:L

[ross_jsy]

Yes it's down to the diff as the zf unit doesn't have an overdrive 5th gear.

[daymo69er]

ahhh, soon to try source a lsd but there soo expensive lol!

[daymo69er]

ahh yeah thats not bad, i was looking over here and people wanted like 550 for one its nuts! ,

[ross_jsy]

It has "unknown" (read as known starship mileage that seller would rather withhold), £100 P&P and will need a rebuild guaranteed. Top work as usual rich, as you say the zone is full of people milking it

[daymo69er]

i suppose its worth paying a bit more knowing what you are getting then? ,

[ross_jsy]

Like with anything. Personally I would always factor in a rebuild as the youngest are roughly 20 years old and they have a finite life due to clutch plates wearing

[daymo69er]

how much does it cost to get them rebuilt? , and what do i have to do to swap my small case for a medium case diff? , its something i will get done aventually! ,

[ross_jsy]

PM a zoner called Gareth, he is the diff guru on here. And you just unbolt your old diff and install the new one, the prop length might need adjusting slightly though

[rich318i]

Gareth 100% all i hear is good feedback with his work

[daymo69er]

the diff guru haha class!!! will do mate i been told the prop has to be shortened but i will pm him now and ask, ! , so much to do , but just need so much money! ,

My work is always top. loving my S52 cams by the way the car a flyer not many cars out there can keep up

Quite surprised it tops out at 95 mph with a 2.8 engine, when with the standard 1.8 it would do comfortably over 100 mph - in fact, 114mph, according to this link:

[ross_jsy]

He is using the 2.8 box which has a direct 5th gear as opposed to the 1.8 which has an overdrive 5th.

That's nice rich, very on topic

z3 torsen diffs are nice no worn cluth plates to worry about here is one on ebay

[daymo69er]

i was just about to say that with the 1.8 in it i think i pushed 120 out of it at a stuggle but the engine was pretty abused, and smoked like a bitch! , but ross_jsy wha you mean by an overdrive 5th?

[ross_jsy]

The zf box you have has a direct drive 5th gear I.e 1 revolution on the input shaft equates to 1 revolution on the output shaft. The getrag box used with the 318i has an overdrive so every 1 revolution on the input shaft equates to more than 1 turn on the output, hence why your diff is geared too low

If that's a Torsen diff, it's a bit of a bargain.

[daymo69er]

is there any way to tell? ,

[Motorhole]

A Torsen behaves like an open diff when unloaded so iirc, the only way to be certain is to drain the oil and remove the backplate.

[Jamie8GTi]

This post has answered a few of my questions, Thanks guys! 95mph though! must be painful to drive sometimes

[JF008]

So daymo69er, have you found out how much in an LSD rebuild?

[daymo69er]

and around town and that its not to bad got so much bottom end power i normally keep it in 5th and pulls virtually everywhere just when i get on the motorway is the bitch, sounds like an aeroplane taking off with the stupid exhaust i got on it at the momment lol! ,

and jf008 not yet mate i aint really looked into it as waiting to hear back from my new job! and as got baby on the way car has took a step back at the momment! ,
