I was originally on a M3 3.0 LSD (3.15 Ratio), Medium Case (188mm)
I've rebuilt it with a 3.46 ratio (tops out about 140mph in 5th, but much better mid range), a pair of new clutches and new bearings mid way through last year.
Many people swap to the 3.2 large case (3.23), but then you are...
So the week before Snetterton I swapped the slide pin bushes on each caliper - these are just rubber from factory, and tend to make the pedal go softer the hotter they get (as the caliper flexes). New spring clips/retainers combat this somewhat, as they stop it flexing as much - although the...
Cool - No doubt carrying more speed onto the straight at Spa, around 115mph after Eau Rouge, so only another 20mph to go (uphill mind). Luckily I didn't go for a 3.6x ratio diff as I think that would have ended up being far too short for UK circuits. The 3.46 seems to be the perfect all rounder...
Possibly, never really looked at what speeds people usually get down there - the limiter is 225kmh/139mph in 5th, just about hit that on the straight at Spa
Yeah, very lol. Taking a risk and heading to Snetterton in mid December to see the year out, few bits to do before then. Hopefully get lucky and have a dry spell!
Nah, it would be fun but I don't really want to considering the amount of wear it puts on everything else (as happened with the Mk1s).
The Mk1s were cheap enough to maintain, but with the double balljoint setup at the back of the E36 (nearly 100 quid to replace all four), and cost of bearings...
I've turned the few milliseconds of fuel on over-run off now.... we turned it on a long time back to try and solve some 'drop to idle' issues when you clutch down, but forgot it was still on. It puts out a bit of oil when lifting off at high RPM and I think it was just igniting that, as its...
Car is now 82db static, still quite a bit of noise under load though which is fine.
Oulton yesterday - dry(ish) in the morning then monsoon in the afternoon. First time back there with the 3.46 final drive, much better, mostly 4th and 5th gear now. New suspension feels better as expected. Lap...
So after exploring options on replacing the front shock, well the pair, it turned out the components would not swap over anyway so I had two options.... keep using the dodgy shock or replace them. After speaking with the original supplier (had them around 2.5 years), I got another set sorted...
Had a quick check over the car before Donington, and felt a slight bit of play in the front N/S wheel bearing, or so I thought. These have never been replaced before, so I swapped it for a new one...
After fitting, the play was still there. Turns out the play is coming from the shock itself...
A couple of days before heading off for Spa I had the car out and noticed the wideband going off the scale at high RPM/wide open throttle. Panic set in and I thought there was an issue with either the map, fuel system or engine itself! I logged a bit of data and the wideband was bottoming out at...
There has been a massive amount of changes over the past month, with the above being just one. Days have been spent stripping l excess wiring out of the engine and interior looms, then rewrapping everything and generally tidying things up. This saved a good 4-5kg which I could not believe -...
Been working on this quite a lot recently - not fully completed a lot of the jobs yet but here is a start..
I wanted to change to E36 M3 3.2 rear arms, which use a much larger wheel bearing, to try and resolve the issues previous in this thread. The plan was to keep my subframe (so I stay with...
Since replacing the shafts (and bearing), then a new nut, which was locked on and marked up, I did Cadwell only to find play in the N/S again. Worth mentioning the O/S is still on the same bearing from the original build nearly 2 years ago, which has never been an issue. N/S is obviously the...
I don't know really.... but its one way to learn :)
Got the LSD back on the car today, after filling with oil.
Everything seems great, and the ratios are much better. No noises or leaks as of yet - the LSD operation is much sharper too. Once back, I tested the breakaway torque at around...
So I got a set of bearings, went for a decent brand that most seem to go with...
Cleaned the outer housings and drove the outer races into place..
Pressed the other half of the bearings onto the LSD unit..
Next was to clean up one of the cases and mating faces..
The first step is...
After getting the final internal LSD bits I got on with putting them together. First on was the 3.46 ring gear, with Loctite 271 on the bolts and torqued to 110lb/ft.
The standard 'clutch stack' is made up from a 2.1mm spacer plate, and the 2.0mm friction disk, giving a total of 4.10mm. There...
After removing the M3 differential from the car, I removed the LSD unit from the case. Removed the bearings and ring gear, then the internal assembly.
Cleaned up and checked all the internal LSD components..
The friction discs are well worn (1.93mm down from ±2.1mm when new), I don't...
As mentioned above, LSD rebuild is the next job. Been collecting parts over the past few weeks. My current final drive ratio is from a standard E36 M3 - 3.15:1. Luckily with BMWs, a lot of that era (E28, E30, E32, E34, E36) used the same dimension hardware (ring gear and pinion) inside the...
All I can find at a glance is an old post - http://www.cliosport.net/threads/fitting-the-decat-to-manifold-with-no-springs.529839/#post-7042725
Not sure on year but factors usually have a massive book and you will recognise it straight away if they get onto the 406 page
With the standalone offering a serial data feed in Modbus format, I could quite easily write a small C program and use a tiny microcontroller instead of the Raspberry Pi like I did with the standard ECU. This just logs every piece of data, over 200 channels, (at a much better rate too) to an SD...
