here's a more realistic update. please enjoy!
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:
- Fuel Gauge
- Speedo
- O2 sensors aren't plugged in
- 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.

some more updates. some quick shots i took last night.
Please note that whatever that is beneath this are pictures and details of the previous V12. That project is scrapped for what's above due to driveability issues.
OLD V12
Hi guys, It's Tom again. Been a long time since i posted. I've embarked on a new project. A V12. I've posted it in chronological order... please enjoy...
Oh yeah, coming updates:
- Custom exhaust manifolds
- Custom adaptor plate for M20 manual transmission (i know, i know)
- Electric radiator fan
- Powerflex full poly bushes

Some pictures of my painted intake manifolds. I chosed a red and black theme. If you got it, flaunt it. Which explains the red pipes, all 12 of them. The intake manifold are really special, they are 2 seperate interlocking pieces.
But what’s also interesting is, they are 2 exact same pieces, just reversed, and!, the right intake manifold will supply air to the left bank of the 6 cylinders and the right manifold to the left cylinder bank! There’s still some work left to be done.
I used a can of black truck bedliner spray to lay the base with a good and strong rough finish. Then i masked the plenums to do the red ribs with an enamel red spray can. I then removed the masking and topped it with a can of clear flat spray since i couldn’t find any flat enamel red.
The lighting was poor and yellow so the pictures don’t really do justice..
I will sand the embossed parts of the black plenum when it’s ready to be put on. When everything is in, the red ribs will stand out like nothing else!
The next few updates will be my:
- Custom exhaust manifolds
- Electric radiator fan (either a used Mercedes one or a new aftermarket performance unit)
- Radiator (i might get a new all-aluminium performance unit of just re-use my M20 radiator)
- Other stuff i forgot to mention
Custom CF Head covers 
The good guys at Duke Racing who’s in charge of the whole conversion applied their carbon fiber building and wrapping skills on my head covers. I opted for CF wrap-on on my head covers and full CF injector cover since it’s much more obvious being one of the highlights of the engine bay and the fact that it’ll be removed from time to time for maintenence purposes.
The CF head covers is a tedious job. It failed a couple of times. they’ve got the driver’s side cover perfect but will be re-doing the other side. The excess will be cut and several layers of clear coat will also need to be applied before the final product can go live.
As for the injector cover, they are still on it. I’ve taken a look at the mould for it and it’s perfect. The cover will be popping out from the mould really soon, so watch out!
I've also created a blog for my V12 project, so if you like, please go to

It's me again
progress is slow,
we've just pulled the engine.
will be cleaning it up and probably swapping it in next week!
Please provide some ideas on how i should detail it? like what colour combos for the head covers and intake manifolds(s)
i've seen some with red covers and black intake which is pretty nice. but i'd like to see what you can contribute?

Okay guys, I've just gotten myself a front cut of an E32 750i. An M70 5.0 V12 and all necessary harnesses to be exact.
but unfortunately, it's an automatic like all of them 750i
sounds crazy huh
Enjoy this!
Now,
I'd just like to know
- If anyone here has ever done an E34 V12 conversion before or at least tried or has relevant articles on this?
- Inputs on engine mounts
- Harness/wiring input
- Shortcuts
- Any 750i or 850i owners know any common bugs or problems with the M70 V12 which always need to be looked at or replaced?
- Transmission: Any known suitable manual transmissions?
- From BMWs
- From generic jap cars?
- Differentials: currently. it's a 2:09.
- Say i stick with the automatic, what kind of ratio should i use better accelaration, or if its good enough stock?
LSD options? would the regular units from the E30 and E34 be useable? - What kind of Preps to the V12 before dropping it in?
- Messing with the V12!!
- Easy ones? Intake, Chipping, Exhaust, would any yield any performance gains?
- If you have other inputs, please do share them
All help appreciated!
Thanks!
Tom
