and both running strong.

Heck the 1992 just passed Illinois emissions, fast passed in under 30 seconds. And it's engine oil stays clean all the way till the engine meter tells me to change it (synthetics only).

Generally replaced most suspension components, but nothing on the engines.

1991 535i 5-speed.
185k, new HG (HG was original) at 182k.

Owned only since 172k, 10/03. Nothing 'major' before that in the records.

Hey Winfred, will you keep us informed about how the 4.27ls works out, I have been curious about how the performance changes?

I bought this car new. It is now pushing 180,000 miles, and is my garage queen and track car. I trailer it to the track, mainly to keep mileage down, but also for insurance that I will be able to get home if something breaks.
My first mod was a Dinan DME and transmission chip. I still use the transmission chip, but switched to a Conforti DME chip. Second mod was polyurethane thrust arm bushings at about 50,000 miles. Still work fine, never had any shimmy.
I put in a (way overpriced) Dinan air intake tube. It doesn't stay in, do I just run without one through a K&N filter. I have Schroth 4 harnesses in front.
Suspension mods were next with Bilstein Sports, H&R springs, and Racing Dynamics anti-sway bars and front strut brace.
I have a SuperSprint cat-back exhaust system, and installed UUC "Very Serious Brakes front and rear with stainess steel brake lines. These are alloy two-piston calipers made by PBR in Australia for the recent Z-06 Corvette. They use off-the-shelf BMW 850 front and 540 rear rotors. A worthwhile mod for the price compared to Brembo or Porsche kits, and still offered by Ireland Engineering in LA.) I use Hawk "Blue" pads.
I had Brett Anderson of Koala Motorsports rebuild my differential with a 3.46 gearset using a Quaiffe torque sensing gear locking unit. Filled it with Redline gear lube. While I had the diff out, I replaced all of the rear subframe bushings, mounts, and Pittman arms, as well as the center driveshaft bearing and guibo.
The car has new engine and transmission mounts, transmission selector seals, and tie-rod-ends.
The most recent mod is a custom all-aluminum radiator from Ron Davis. This made a world of difference in my tendancy to overheat at the track. I also replaced the waterpump, belts, idler pullys, and cooling system hoses. I discovered that I don't need the engine-driven cooling fan (or viscous connector) or radiator shroud with this setup.
I used mineral BMW 10W 30 or 20W 50 for the first 120,000 miles. Now I use Mobil1 0W40 or 10W50, and it doesn't use a drop. I use BMW coolant 1:1 with distilled water and a pint of Water Wetter. I had a leakdown done at about 150,000 miles out of curiosity, and it passed. Some cylinders were fine, others had a little wear, but none were out of spec.
This is controversial, I know, but I have never changed the original "lifetime" transmission fluid. I have had virtually no problems with the transmission, and I certainly don't baby it.
I use BBS RK 17 x 8.5 wheels with Kumho Victoracer 245/45-17 tires all around for the track, and Mille Miglia 11-2 17 x 8.5 with Bridgestone Pole Position S-03 tires all around in the rain and on the street.
Unusual repairs that come to mind were cruise control module (expensive!), and fuel tank "7-way" vent valve. My fuel tank partially collapsed due to unvented vacuum. I also replaced my radio with another stock unit. I used BMW mud flaps for the first 150,000 miles. They looked OK, and helped protect the paint which is all original. I have put the Euro front and rear bumper strips and front license plate covers on.

Future plans/projects:

Replace original "sandblasted" windshield
"Shadowline" trim
Rear side and back window tint
"Smoked" headlights and tail lights (?) opinions?
Repaint (Oxford Green)
I have collected all the parts I need to do a conversion to a six-speed manual that came out of an e-39 except the lightened flywheel. This includes the pedal box, clutch master and slave cylinders and hydraulics, M5 clutchpack, Auto Solutions custom short shifter kit, Ireland Engineering transmission mounts, guibo, driveshaft, and brckets/hardware.
I want to develop a Lysholm-based twin-screw, air-to-water aftercooled supercharger setup for this car at some point if one does not become available.

64835 miles.

No real mods except I pulled the Motorola phone and the coin box which was also in my way. 60K mile service done last month and the mech says I'll need new brake pads in the next 3-5000 miles. Run premium fuel and have been considering getting a set of regular Bilsteins but with two tuitions coming due this spring, I'll probably do nothing.

Been running dino, 20-50W - summer, 10-30W - winter.

BTW, these cars suck on ice, I had to make a run at a minor right hand sweeper with a 15 foot grade over 40 feet and the wheels spun out. Took 5 runs at it. The old Audi quattro wasn't even phased when I came back in it to pick up my son.
