Some Pictures of the 750i Auto transmission rebuild

dsc_89051

Here’s yet another installment of my project 550i V12. Though there were plans to bolt on a manual transmission, it has been temporarily shelved. This is due to the chronic slippage from the auto transmission a few days ago. Though it was already slipping when the car just came out of the shop, it was still drivable. The final straw came when some technician took it for a drive after correcting the wheel alignment. Anyways, here are some pictures of the disassembled 750i transmission. Look at the size of the torque converter..

Here are some new pics of the new 750iL V12 complete swap

Finally. Here are some pictures of the 550i’s latest progress. Sorry i did have the car washed 2 days ago but today’s rain ruined everything. Since i’m bringing it to the workshop later, I’ll leave it for now. The guys at the shop will get the finer details sorted out. What’s lacking currently:

  1. Fuel Gauge
  2. Speedo
  3. O2 sensors aren’t plugged in
  4. Minor wiring Issues

Yup, i have been driving it that way for the last week. I have also had the exhaust connected to just the center section for now(again). It’s pretty loud, but just not anywhere near refined.  With just the center section now, it has that subtle burbling like a turbo would but dominated by the creamy V12′s nice growling howl. I’m planning for a more final exhaust system soon.

Parts of the engine are pretty much as-in from the donor, oxidized, roasted.  I’ll get it all detailed and painted soon.I may even put in the metal mesh air filter pods.

As i’ve mentioned, the old V12 was replaced with a more complete 750i swap. So, again, it’s essentially a 750iAl with an E34 shell(maybe). A Far cry from the then, manual  transmission and throttles. It’s just so much more tamer now. So much so, that it’s completely soften the intentions of a wild V12 project. Though i’m kept happy with other attributes that make the 750i  such a fine cruiser. But i’m determined to hack it as far as i can.

The magnificent V12 is a sight to behold. Did i mention i had the whole bay degreased in Simple Green? My all-time favourite multi-purpose cleaner. Know where the oil is filled? The central oil filler made my buy that little more worth it. Most 750is in existence now have got their oil filler near the firewall, which doesn’t look nearly as good as the central ones on the 850is. Try browing pics of my late V12. I have also got used to the central expansion tank that were only on the Bigger fives and sevens. looks good in there too. Continue reading

First Drive. V12 E34 Video with center exhaust

YouTube Preview Image

90% completed and out for a drive, here’s a video of it. Though not much of a visual video, I recorded this more for sound. Should be able to hear the V12 growl from nothing but just pure stainless steel headers rushing to just a AC Schnitzer center exhaust. Continue reading

Update on the V12 E34!

YouTube Preview Image

Here’s a video of my almost-complete project V12 E34. I now have manual throttle bodies instead of the drive-by-wire ones. I had problems with drive-by-wire throttles due to the absence of the stock automatic transmission and probably some other sensors which just seems too tedious to incorporate with my plans of fusing the V12 and M20 harness.

In the ECU compartment there are a total of 4 ECUs. Continue reading

Wiring is complete on my V12 E34. So, Enjoy the video!

Okay, it may not be totally complete. But the guys at Duke racing did manage to get the V12 started!. I made short video of it. Why is it so short? well, because of these key components.

  1. Running on a makeshift single fuel pump instead of twin
  2. No fuel filter
  3. No oil filter
  4. No gas pedal
  5. No Exhaust

Starting the M70 V12 before buying

[wp_youtube]xr5bh6dzGDM[/wp_youtube]

Here’s a video of the mechanics trying to start the engine to make sure the V12 works before i buy it. It did start, but had really lumpy idling. I found out after that that the 750i ran on 2 fuel pumps and the guys at Duke Racing used only 1 fuel pump to supply fuel. Nevertheless, it was still a joy watching the marvelous engine come to life – almost.
