E30 Zone

- I removed the diff body (that which has the crown wheel attached) - visually inspected the bearings on the body, and in the housing. - rotated the pinion shaft (check for consistency and smooth rotation) - checked the breakaway torque of the LSD-pack what I did not do (and regret now 😅) - check pi...

update: spoke to a local mechanic, and he mentioned it could either be the pinion bearing (they tended to wear faster) or indeed the 'meshing' of the pinion&crown. If the noise was very slight, and I had opened the diff before, it had no use to do so again. He recommended to just continue as is, and...

Hello guys, I swapped to a limited slip diff last week (best decision ever). I bought it second hand, so I disassembled it partly to check what condition it was in. I found that the bearings were like new, and the breakaway torque was nicely within spec (mine had 63nm, spec is 50-70nm) so I decided ...

Strange that, 80s petrol in the UK at least, was leaded and delicious and nicely knock resistant. Really interested to see how advancing your timing affects EGTs. Did you move your thermocouple in the end? Haha i'm sorry to dissapoint, no i didn't... In this case i'd have to disasseble too much, fo...

Hello all, I wanted to post some extra info, because I've been doing a lot of research into ignition timing. First of all: The ignition timing chart I used (BMW original) somehow seems to be EXTREMELY RETARDED given the engine's specifications: https://pasteboard.co/JJIARcz.png The Germans where eit...

Can't see the image again unfortunately. Interesting article here: https://www.bimmerforums.com/forum/showthread.php?1806297-Tech-talk-Why-2v-heads-need-more-advance-than-4v-heads Pretty sure your car will take off like a scalded cat with more advance! f*** me again... do you happen to have a good ...

In the following link I pasted a picture of my current ignition map:

https://pasteboard.co/JIdcKYG.png

again:
Below atmospheric pressure (-100 - 0) is based on standard calibration BMWM10B18, with some timing advance.
Boosted partition is based on Audi TT map, yet slightly retarded for safety.

The junction temperature is fine above 1000C, if the datasheet for your sensor says lower It's possibly some other limiting factor like insulation materials. Bung it on the manifold and see what happens! They're cheap sensors ! As a quick experiment, you could advance your boosted timing map 10degr...

Have you checked mixture or for air leaks? I have only seen this on cars running weak

It's got a lambda sensor post turbine, and the mixture is quite rich (0,85 - 0,70 under boost). So i don't suspect any issues there.

Must admit I've no idea what constitutes a reasonable EGT. What type of thermocouple do you have? K type goes above 1200C if you can lay your hands on one. Suspect if you've a K type with a lower limit it'll be the insulation or some other limiting factor rather than the usable range of the junctio...

Maybe worth putting the thermocouple in the manifold, as you say, the turbo is powered by heat so the temperatures measured are going to be lower than in the manifold. Would certainly encourage you to look at your timing 🙂 Yeah i know that would be better. But we've had these thermocouples break (a...

In the mean time i also installed a thermocouple POST-turbine, and did some measurements: - 35kmh, 2nd gear, 2000 rpm(ish) --> 550DegC - 50kmh, 3rd gear, 2000 rpm(ish) --> 600DegC - 70kmh, ?nd gear, 3000 rpm --> 750DegC - 100kmh, 5th gear, 2500 rpm --> 750DegC - full load 0 - 140kmh peak (at 140kmh)...

It's worth measuring the exhaust gas temperature I'd say. Metals will glow red around 600C, can't see the image unfortunately so can't see how red it is. Couldn't tell you what a normal EGT is but sure the internet will! Worth determining if there is a problem before trying to fix it! My first susp...

Stainless steel grade304, 3mm thick.
Yet that should make a difference wether it glows or not. Only when it will stop glowing

hehe..

Yep.

If i make it spark at TDC, (advance = 0) the crank pully mark will line up with the aluminium pin sticking out the front.

Hello, in the past year I installed a Haltech ECU, with all necessary components for controlling the engine. after properly calibrating, and testing for a few months, I installed a turbo from an Audi TT (K04-22) on the engine. Currently, everything is running fine and the car feels great. (I am runn...

Hello friends. The last year my '84 318i has been standing still in the shop, because it is receiving some new equipment :) - I have installed a Haltech e8 ECU which I've mapped up to 100Kpa (relative) - Installed 250cc/min EV6 injectors (I have to see how long these will hold up) - Stainless steel ...

i checked the bentley.
but it only has the front ride height somehow...
I'm sure i didn't miss anything

so has anyone got the rear ride height?

Hello gentlemen, I've been thinking about lowering my e30 for a while (i think it looks odd right now). I think mine has already been lowered in the past, yet they left the standard springs in the back. my current ride height: (axle centre to fender) F:345mm R:380mm approx I have a euro e30 type-1 3...

If its not your fault shouldn't the other persons insurance be paying for the repairs? That's right, But the thieves that work at the insurance company only gave me an X amount (which was almost enough for all of it). they do that because hypothetically if you were to sell your crashed car, you wou...

excellent idea, will probably try that some time this week on the "to be replaced" bumper

I'm not so sure about that. my previous bumper had some discoloration from the sun i guess, but this is too localised don't you think ?

i checked the trim pieces, and ebay prices bring me up to around 150â‚¬, so that would indeed be an option if i can't find a way to fix this.

Hello Friends! Crashed my car a while ago (not my fault and yes i'm fine thanks for asking), this left me with a broken front and rear bumper. After a lot of searching (i live in Holland and bumpers are scarce) i found a front bumper. It had some odd stains in the plastic bits, but the price was oka...

UPDATE: I had taken it for granted that instrument lights wern't working (i don't drive at night a lot). but then i noticed that the lights on the right hand side wern't working. Turns out fuse 23 was blown, and it kept blowing after replacement. After a few hours of browsing the web and searching f...

anyone?

Alas, they did not.
i gave it a good shot though, the bulb was burned out.

What's next ?

see this is why i asked

i will be right back.

Hello brothers. The other day i noticed my instrument lights stopped working. I did a few basic checkups (the ones that were obvious to me), but none of them got it back in working condition. I searched the wiki but didn't really find anything of use. Could anyone point me in the right direction, wh...

hasn't really cleared it all up yet. what your saying is: buy a 325, 2-door, in the colour burgundy and revise it for maximum worth, that part is clear to me. but if i buy a 323 aut, which is frost white. restoring it to a brand new 325 manual burgundy e30 how much difference would that make from th...

Hello boys and girls. some time in the near future (to be defined) i intend to start restoring an e30. at the moment i own a 318i from 1985 colour burgundy. it's got quite a bit of mileage and some of the previous owners weren't too choosy when buying parts, the paint was redone in some places and t...

AND WE'RE DONE! I first used the penny trick to figure out where i needed to be. then used some different diameters to see what rpm they achieve. then machined a piece of nylon PA-6 which i could fit into the hose. i have a m10b18 and the hole i used was just above 3mm and that got me around 800 rpm...

can you "unplug" the small board or does it require soldering too ?

(reinstalled the board so i can't check)

FOUND THIS:

http://www.verrill.com/car/e30_idlefaq.shtml

Good info for anyone with real problems.

Add to wiki maybe ?

it's white.
is there a way to decrease this ?
