I SWEAR THEY JUST FOLLOW ME HOME...

I saw it. It fit the bill. I had to pick it up, wife-approved. Alongside with 4 other cars.... Or maybe it was 3, i can't remember it was in early September 2015. Anyways here it is Arktisblau E23 1984 745i with a busted rear window that ended up in my driveway.

This is one of those adventures involving my buddy Sherman, I know you wonder who is that guy. If you have read my other two earlier posts, the name should ring a bell. I promise I will tell you all about him later. We bought 4 cars together, he was supposed to take 3 of them (E32 735i, E12 528, E23 745i) and this said blue E23 745i. That day I jumped in my truck, picked up his dolly and off we went loading up cars.

For Sale AD

First modification after rolling it into my driveway was to fix the rear window (the plastic bag was temporary done by the previous owner). What a mistake! That tape was impossible to take off a month later, but the rain did stay away from the insides. Sherman had in store a spare window, in exchange of my transportation services. A buddy of mine from work, came over one night and installed in less than 10 minutes. Little that I know, in his previous life he did this for a living for 15+ years.

At this point, it was time to start figuring out why the car wouldn't want to crank. Found a hidden battery kill-switch, that wasn't it. Thanks to the simplicity of the early BMWs, jumping two terminals under the hood in the diagnostic port yielded the first success. Some calls later to the gurus of the E23 world, it was pinpointed that the no start problem could be the neutral safety switch, yeah one of those fancy features so you don't start your car in anything but Park. Yes, the 745i is automatic. Did I mention it has a turbo?

THE 745I WAS A SPECIAL HIGH-PERFORMANCE MODEL OFFERED IN LEFT-HAND-DRIVE EUROPEAN MARKETS BETWEEN 1979 AND 1986. IT WAS ORIGINALLY FITTED WITH A SPECIALLY PREPARED 3.2 L (3205CC) VARIANT OF THE M30 SIX-CYLINDER GAS ENGINE AND A KKK K27 TURBOCHARGER PRODUCING 252 HP AT 0.6 BAR OF BOOST. THIS ENGINE WAS DESIGNATED WITH THE BMW ENGINE CODE M102. IN 1982 THE ENGINE GREW TO 3.4 LITRES, CHANGED OVER FROM JETRONIC ENGINE MANAGEMENT TO MOTRONIC, AND WAS KNOWN AS THE M106. DUE TO HIGHER DISPLACEMENT AND BETTER ENGINE MANAGEMENT, THE M106 DEVELOPED THE SAME POWER AS THE M102 AT ONLY 0.4 BAR BOOST.

Not much happened in the next almost 6 month. We moved to a new house, and I also focused my energy on the low-mileage S38 that lives now in my M5. The M5 was daily driver status and I was ready to start working on the 7.

Keep an eye next week on more work that I have done to the E23. Upcoming are suspension; fuel system; interior; engine... (this article is a rePOST, as the original from a week ago, disappeared in the oblivion). Part 2 is called THE 745i ADVENTURES (PART 2)

  • Yeah, I brought it to the D_TRB team's attention and they suggested reposting it. I totally agree - the e23 is amazing chassis that doesn't get much love. Probably the cheapest grey market/euro car out there.

  • Ah Ha! There's part one! I thought something must've happened when I couldn't find it. lol Thanks for sharing Pavel, the e23 is such a fantastically agile platform for a big car that is sadly so underappreciated. We need to bring it the attention it deserves! Nice save!
