Rare and expensive parts!
I don't remember if I checked with CMS, I think they were out of stock.

I thought my 1st slider was very worn, but I got a second opinion that said it wasn't too bad ...

Very interesting to see the guts of the G31! I'll be there with you sooner or later... I still can't believe how well mine has held up, and how well I've adapted to driving it, despite seemingly no 1s ...

Sorry to hear this one has turned sour on you; it sounds like a decent car that was probably shined up and had some mechanical issues swept under the rug. Unfortunately, all too common - not that that ...

It's such an irony that my position ten years ago leaned towards ditching K/KE-jet when I had the time and money to switch to EFI. Now, however, I have no plans to retrofit any of my three K/KE-jet en ...

Oh, sorry - I was just thinking ignition because I'm planning on keeping K-jet and thought I'd discussed that with you, but come to think of it, it was someone else (maybe @Fasteddie313). I know there ...

You can find anything you'd need at a parts store, but for the price of a handful of connectors, you can buy an assortment online with a hundred or so pieces of the same or better quality that will co ...

My 931 had/has similar issues - maybe not as bad. I'd dig up something called Deoxit (a deoxidizer for electronic connectors and components) and give every contact a squirt. One issue I had was my bli ...

If I go with the Microsquirt, I'm thinking I'll convert to an EDIS-4 setup, and if I remember right, that also has an output to a fuel pump relay, so it's also an opportunity to upgrade the fuel pump ...

Well, the heat is better now... I think the heater core is in better shape than I thought, it's just the lack of airflow meant it couldn't go anywhere. The strange thing is, now I'm getting nothing bu ...

Another "long time, no post!" I just drove the car for the most part last summer, and with the mild winter we've been having, I've been using it a couple times a week. Big contrast there, to ...

I looked around for a kit when I was working on getting my car going, but ended up buying the same one as Chuck. That was partly because there was some pitting in the bore of the old master cylinder, ...

morghen is right about the gunk all through the system: it's probably gotten into everything. There are several internal filters in the system, and while they're not prone to plug up, it could easily ...

I had the same thought as safe: there's some pretty obvious repair work. I suspected you'd find worse the more you dug, but the second set of pictures don't look that bad. Still, my rule with repair w ...

Absolutely remove the warm-up regulator (WUR), disassemble it, and make sure the passages are clear. Don't worry about screwing it up: as long as you don't lose any pieces and put it back together cor ...

I've never found any good source for such schematics, and it may be the kind of thing Bosch and such companies kept to themselves. VW and Porsche (and other manufacturers) never publish that kind of t ...
