    Not a weird question. I’m still learning how to ID BMW diffs and have learned the hard way more than once not to trust the word of eBay sellers. thank you everyone for helping me figure this out. Looking forward to getting it rebuilt and situated with my 5 speed swap.

    Photos of the lsd and stamping. this was a cheap eBay find, so well aware that there will be some figuring out to do. I also know the rarity of the 4.11 and was skeptical when I bought it. There are no stampings on the side of the diff which is odd. My plan is to add new bearings and seals, then install it with my 245. 4.11 would be amazing, but 3.91 or 3.64 is also fine. it is missing the front yoke and one of the half shafts, so will have to move the yoke over from my current diff and source some redrilled e21 half shafts for it.

    Hello everyone, looking for help identifying this diff that I bought for my 2002. It was sold to me as a 4.11 2002 diff, although the 6 bolt side cover suggests it is likely an e21. no stamping on the drivers side, no S, but there is an LSD in there. I have yet to count the teeth to determine the gear ratio. The biggedt thing I want to know is what parts I will need to rebuild/ reseal it and install in my 2002. Verifying what car it originally came in is the first step. thanks, Chris

    Hi all, looking for a little tuning advice. I recently installed a Lynx manifold with dcoe, and have loved it on my 2002. With open velocity stacks, the carb runs perfectly with 38mm chokes 55f8 idle 155 main 180 air correctors F16 emulsion tubes I recently bought foam air socks for the trumpets, and cannot get the car to run well with the filters on. It will idle fine, but is clearly starved for air under WOT. Remove the filters and it runs perfect again. I’ve tried dropping my main jets all the way down to .140 but there was little to no difference. Next I will try changing the air correctors, but my understanding is that the air correctors really only affect the top end. any advice? I am really surprised that the foam socks are this restrictive and can change my jetting so much. For those with the Lynx 45 setup, what air filters do you run and how has that changed your jet settings? thanks in advance, chris

    Thanks, it’s weird to me that changing pump jets didn’t make it much better at all. I understand the physics behind it though. In the British car world, SUs have that front damper that essentially gives a variable choke size to help with this problem.

    Hi everyone, thanks to some previous threads on the forum, I have gotten my Lynx, single dcoe 45 setup very close on my 2002 (engine rebuilt to stock specs). The issue I am having seems to be on the pump circuit. At idle, if I go to WOT, the car stumbles hard and sometimes dies. It does not have this issue above 2000 rpm. I’ve tried a variety of pump jets between 35 and 60, and even no jets at all with no noticeable change. There do not seem to be any vacuum leaks and the car idles perfectly. current jet setup is idle: 60f8 Main: 150 Air corrector: 180 emulsion tube: f16 chokes: 36 pump: open stock fuel pump and tii distributor set to 7 degrees advance at idle. Pertronix ignition and flamethrower coil (no external resistor) Could this be a fuel pump issue? Would it be worth switching to an electric pump? No AFR gauge to tell if it is going lean or rich at WOT. Thanks in advance, chris

    Thanks all, email sent. For some reason I couldn't find email addresses on the mobile version of the website. Easy to find on the computer. Fingers crossed

    Wondering if anybody on here has been experiencing a delay with IE lately? I put an order in 2 weeks ago, and it still hasn't shipped (Estimated processing time is 6-7 days). I've bought a lot of stuff from them in the past with great results, but am getting nervous with the timeline. I am getting shoulder surgery at the end of the month which means no working on cars for 8 weeks. Need to get the 2002 finished before then. I've tried calling a few times to see what's going on, or cancel the order, but it goes straight to voicemail.

    Based on my note above (priority is dirt roads, and vintage rallies) do you have a kw setup that would fit my application? Right now I’m running ie stage 1 springs and bilsteins. Overall I feel like the setup rides well, but am annoyed at how the springs constantly unseat when at full travel. In addition, I’m a mechanical engineer and like to tinker and adjust setups to my liking. I’ve been thinking about trying coilovers to fix the unseating problem and give myself a new aspect of the car to play with. I’m interested specifically in KW because I know they have a solid reputation and build quality.

    Thank you, yes I realize this. Everything has trade offs. My priorities for this car are dirt roads and vintage rallies. For the few times I will be autocrossing it, I can deal with a softer setup.
  11. 71roundie67mgb65spitfire
    Would love to learn more about this.
  12. 71roundie67mgb65spitfire
    Thanks, I will have to do some research to see if a KW v3 is going to be too stiff for dirt even in its softest settings. I've seen Ceika also makes coilovers for the 2002 and have a rally/ gravel option, but for around $1,000 I am very skeptical of build quality.
  13. 71roundie67mgb65spitfire
    More details? Do they only make them in their V1?

    Hi All, I have been looking through suspension options for my 71 2002. My goal with the car is to run rallycross, dirt roads, daily driving, and some autocross/ track. As such, I have been looking through options that have some adjustability. Does KW make coilovers for our cars? I found a few old threads saying they do, but haven't seen any options online. Any other suggestions for a suspension setup would be appreciated. I am currently running ST swaybars, IE stage 1 springs, and bilstein dampers with poly bushings and 13 inch tires.

    Great engine bays, and still using the stock fuel pump I see. Essentially looking to do the exact same with mine. Maybe one day my 71 will have the same specs as your cabrio…

    Pm sent. Do you have the linkage?

    Hi all, almost two years ago I picked up a used and abused Weber 38/38 for my 2002. After rebuilding several times, playing with Jets, etc etc, I just am not happy with it. On wide open throttle above 3,000 rpms, it is fine, but down low and at idle, I can't get the idle jets to perform correctly. I suspect a vacuum leak somewhere, but haven't been able to track it down. I've been thinking about switching to a Lynx setup from TEP. I have a rebuilt motor that is overbored .030" but otherwise stock with headers. In the future I may go with a compression bump and fast road cam, but nothing too crazy. I like the idea of the single DCOE because this will be a long distance rally car for me, and the simplicity of one carb is appealing. Wondering who out there has made this switch and if it is worth the $1200. Another option would be to pick up a new 38/38 or keep diagnosing, although I have never been a huge fan of downdraft carbs. Thanks!

    It could just be the angle of the photo. I didn't do any adjustment when I bought it. I assumed IE assembled it correctly. I should also mention that the wires did not normally touch the cam lobe. I pulled them in to get a good view of the screw. Assuming IE doesn't get back to me, I will likely just buy a pertronix unit and install that. Sounds like the mounting points are the same.

    Bosch Blue, internally resisted.

    Good spot, I haven't looked at it too closely, I just saw the crack in the center magnet and assumed that was the cause.

    Just wanted to throw a warning out there. I bought the reproduction Tii distributor from Ireland Engineering a few months ago. So far I have less than 500 miles on my 2002, and it already broke and left me stranded. You can see in the picture that the center unit cracked. I reached out to IE via email to see if they could help make right of this, but no response so far. I am trying to figure out if I can put a pertronix unit in as a replacement.

    PM sent on Bosch blue, shift knob, and STEBRO muffler.

    You can buy the oe design non sport ansa right now. Rock auto and ebay both have them. I haven't heard much on how they compare to the oem exhaust, but I imagine it is comparable.
  24. 71roundie67mgb65spitfire
    I understand what you are saying, but I'm not really looking for power gains, just a nicer sound.
  25. 71roundie67mgb65spitfire
    I think you are right. I have a 4-2-1 header I bought from someone close by. I just need a good system to attach to it. Ireland and rogerstii are out of their stainless system. I can find supersprints, but after shipping they are over $1k. Going with the top end performance kit, then having a shop fab the rest is tempting, but I haven't seen many reviews. One consideration is that I need it to be relatively easy to remove. I will be swapping the transmission in a few months once I can get it on the lift.
