I've been thinking about what to do with two of the same car (context) and I think I have a plan for the short/medium term.
Grey car is getting all the maintenance it needs and some hand-me-down parts from the blue car (like the belly pan). Blue car is getting some ZCP bits along with brand new parts to replace the hand-me-downs. I did toy around with the idea of stripping the grey car and building an M3 wagon (and the shell into a racecar?), but I just really have no need for that class of vehicle at this point.
So for now, the grey car is going to be made as nice as possible while sticking to a set budget and the blue car is going to continue to be treated as has been since I bought it. It is a bit weird that the traditionally less desirable car (mainly because it's an early car) is getting a larger time and money budget, but I just can't shake the emotional attachment I have to this stupid thing.
Anyway, first thing I did was swap the ZCP steering rack into this car and code the MK60 for the new ratio:
The steering rack was disgusting when it came out of the grey car. Here's a before (after some preliminary cleaning) and after:
I also swapped in new inner tie rods, new outer tie rods and new boots. The rack feels perfectly fine, but I am going to rebuild it in the nearish future just because of the mileage. Have done a decent amount of research and it seems like a job that I should be able to get done without too much frustration. We'll see if that's true once it comes time to remove that inner seal though...
Here's both cars getting their power steering systems bled:
After that came a brand new belly pan:
And that's it? Feels weird to get a job done in a couple hours after the amount of hours I've been spending on the grey car.
Haven't driven this car at all because I don't want to kill the front tires with my very (very) approximate toe settings. Have an alignment appointment on Friday, though, so will post up some impressions after that.Last edited by heinzboehmer; 01-16-2024, 07:40 PM.2002 Topasblau M3 - Coupe - 6MT - Karbonius CSL Airbox - MSS54HP Conversion - Kassel MAP - SSV1 - HJS - PCS Tune - Beisan - MK60 Swap - ZCP Rack - Nogaros - AutoSolutions - 996 Brembos - Slon - CMP - VinceBar - Koni - Eibach - BlueBus - Journal

Alignment done. As expected, front toe was way off:
I say this every time I get an alignment, but I really really need camber arms in the rear so that I can get the camber I actually want (both front and rear).
Anyway, car feels awesome. I am really liking the ZCP rack. The difference in ratio is pretty slight (which is a good thing!), but the difference in feel is huge. The dead center feeling is mostly gone and I really like the weight of it. Excited to rebuild the rack, as it should make it feel even better.2002 Topasblau M3 - Coupe - 6MT - Karbonius CSL Airbox - MSS54HP Conversion - Kassel MAP - SSV1 - HJS - PCS Tune - Beisan - MK60 Swap - ZCP Rack - Nogaros - AutoSolutions - 996 Brembos - Slon - CMP - VinceBar - Koni - Eibach - BlueBus - Journal

Installed some more ZCP bits on this thing recently. First up, the 817.3 MK60:
I moved all the electronics out of the way to make my life a bit easier:
You can just barely see the pump down there in this pic:
With the electronics out of the way, I was able to get a regular ratchet and socket in, so that was nice. It was still a pain to get out though. Had to lift the valve body much more than I expected to get the pump contacts on the 817.3 unit to clear. And then of course I dropped one of the fasteners for the DME plastics under the interior carpet, so had to disassemble a bunch of stuff in the driver's footwell to retrieve it. Anyway, it's now in!
After that came the trim. The passenger's side dashboard trim was falling apart on one side and had previously been reglued on the other, so I separated it entirely. Heat gun and some (very careful!) prying was all it took, but I was left with two pieces that were covered in adhesive:
The plastic was easy to clean, as I could just scrape everything off with a razor blade. I was scared to crease the aluminum with that method though, so instead I spent a million hours rubbing it down with a MF towel soaked in acetone. This is how they looked after some time:
I then used my favorite trim adhesive and a bunch of clamps to glue it back on:
Came out great!
Last thing I did was to replace the window switch that I had attempted to fix with another from the junkyard. The circuit board and switch caps were in worse shape than the one on my car, so I made a good unit out of the two:
And here's a quick picture I grabbed of the car today. Thought the scenery fit the mood, so I stepped out and took it real quick:

"The car developed a small oil leak and I traced it back to the timing chain guide bolt that's located behind the thermostat. Thought it would be as simple as cleaning the threads, applying some threadlocker, and torquing to spec. Turns out the bolt had snapped, which made the timing chain rattle around inside the engine and in turn shear the lower bolt as well. Quickly learned that the rattle I heard around 3k rpm was not the VANOS, like I originally thought."
Holy moly, i think this might be my issue, i have a brand new beissan and i have a "rattle" around 3k rpm and also a small oil leak that doesnt seem to track from any of the usual suspects. For the longest time i thought my rattle might be an exhaust bolt being loose somewhere or possibly how my new headers sound.
I will check this out soon.

I do not want to drain my coolant again

Managed to get through all 32 pages. You're on another level. Amazing work bringing this car to this state.
BTW been there done that living in the city with a project car, your experience with the garage size and nails in tires gave me anxiety just reading about it.
I'll ask some questions:
-with regards to washing the engine bay, anything to look out for with running water damaging components? what cleaners did you use?
-i have some oil leaks i need to locate, along with rod bearings, coolant system and front suspension overhaul. would you recommend pulling the front clip as you did? worth the effort? annoying part is having to pay someone to discharge-recharge the AC.
-now that you have the mk60 for a while, still stand by it not being worth the effort?

To answer your questions:- I don't use anything fancy. Waterless car wash (I use the AMMO NYC stuff) for making things look pretty, diluted dish soap in a spray bottle for dirtier areas and diluted simple green in a spray bottle for super grimy stuff. Just make sure to use the aluminum safe simple green if you're going that route.
- Pulling the front clip is great if the front of your engine is super dirty and you want to clean everything up. If you're already draining coolant, then it's not a ton more work. No need to discharge the AC, the flexible lines going to the condenser allow you to just swing it out of the way.
- I think it was definitely worth the effort on this car because of all the maintenance/work that had gone into it prior to the swap and because I don't really plan to get rid of the car. However, I'm not sure that's true for everyone. The swap is extremely time consuming/expensive, adds zero value to the car and effectively makes no difference in regular day to day driving (unless you're driving like a lunatic). I do think that the MK60 is a much better system than the MK20, and you can make a case that the better ABS makes the car safer on the street and that the better traction/stability make the car safer in the wet/snow. However, for me, the benefits of this upgrade are almost exclusively limited to the track. If this car was 100% a street car, I likely would not have bothered with this.

I'm trying to figure out the best approach for locating, cleaning up, and plugging leaks. Pulling the front clip makes cleaning possible, but then I won't be able to run the engine. Things are pretty tight in there in full trim.

Tackled a small but much harder than expected job the other day: steering column bushings. Not a lot of pictures because I spent most of my time contorted under the dash struggling with the install.
Here's old and new:
(apologies for the terrible photoshop, I grabbed the wrong old bolt for the original pic...)
TIS says to "Install nut with Loctite", but doesn't specify the strength. The old bolt had what looked like red threadlocker, so I used that. Also lubed the sides of the bushings (where they slide against the fixed part of the column) just like the stock ones were. Whatever lube BMW used at the factory looked suspiciously similar to the Krytox I used. Probably some PTFE based lube as well.
Getting the bolt through the new bushings was incredibly hard. Required a prybar and a lot of messing around with things. I think I spent like 20 min trying to get the bolt perfectly aligned with the second bushing before it finally went in. In hindsight, lubing the shoulder of the bolt would have likely made my life much easier, but I realized this halfway through the install and did not want to pull things apart and restart.
Here are the new ones in place:
Bryson told me this, so I was kind of expecting it, but I was still surprised by how much firmer the new bushing design makes the column feel. Telescoping it in and out now requires a ton of force.
Driving impressions are all positive. To be honest, I didn't drive the car a lot with the ZCP rack and old bushings, but I can say that the rack and bushing swap has made the steering feel much, much better. Pretty happy with this!
Also, when I did the MK60 swap, I added a wire for M track mode, just in case I ever stumbled upon a ZCP MK60. Now that that's in the car, I'll be wiring it to the E39 wiper stalk button, so I fished the wire out and set it in a more accessible spot:
E39 stalk is arriving soon, so that'll be going in as well. If anyone reading this has wired that stalk up to a ZCP MK60, please let me know if it just wires right up or if I need to do some electronic trickery to get it working. Otherwise, I foresee some quality time with the multimeter in my future.2002 Topasblau M3 - Coupe - 6MT - Karbonius CSL Airbox - MSS54HP Conversion - Kassel MAP - SSV1 - HJS - PCS Tune - Beisan - MK60 Swap - ZCP Rack - Nogaros - AutoSolutions - 996 Brembos - Slon - CMP - VinceBar - Koni - Eibach - BlueBus - Journal

Hmm, TIS says that both the E39 stalk button and the M track mode button are switching to ground, so I might get lucky and not need to mess with anything. I'll probe my ZCP steering wheel trim and E39 stalk just in case.
