My V12 Mk2 swap

Ok seems i've got a higher hand than the house! There's no V12 section so i'll stick it here for now.

We are using the BMW V12 5.0ltr and a 2010 Audi manual transmission to build a V12 Mr2, the engine will be mounted inline (north/south) and without stretching the chassis, although it will mean a lot of chassis altering.

The engine we are using for all of the mock up is a junker, not sure if we will end up using it or not, but it will do for now to get everything fabbed up.

The V12 has landed so let the games begin! We got to work sorting some fundamentals of the swap, now ignore the grot on this engine, we aren't bothered about that for the time being, this engine is being used as a test mule to make everything from. When the time comes for it to run we will strip it and rebuild it, but until then it only has to be dimensionally right.

First issue we found was the throttle bodies were facing the wrong way, well wrong for an Mr2 engine bay, so luckily for us we found that BMW have made the plenums symmetrical, not only that but they have unboltable ends, meaning you can bolt the throttle bodies on the other end of the plenum and the cover plates on the throttle end.... how cool is that? So we will have that Lambo'esque twin air filters shooting rearwards in the engine bay.

Here's the blanking plates fitted to the normally throttled end...



Here you can see the Tb fitted to the normally blanked end (yellow)... tp fit the other side i need to move the oil filler spout, no biggy.



Work then began on making this leviathan shorter, it's too long at the moment, much as i like sitting close to the windscreen i'd prefer not to have my nose squashed against it. This meant ditching the distributors, a good 2 inches saved here..... i will be using coilpacks instead.



We aren't bothered about how far forward the crank pulley sits, that's in the tunnel so it can please itself.

Lastly we will need to make blanking plates for the distributor holes...



I've also go a plan to ditch the water pump and run an electric remote one.

You're....not even fully done with the MK1 V8 and you're already doing a V12 swapped MK2? The hell's next? A W16 swapped MK3?!

I really like this idea, please follow through. Any plans to turbo the engine? The M70/M73 V12's are pretty underpowered stock. Keeping separate EMS, or consolidating to one EMS?

Turbo or go home. Are you doing this just so you can balance a coin?

ag86IL, i'm going to detail all parts of the project including the LPG install which is one of my former trades, LPG installation that is. It's much simpler to just get this working on a basic LPG setup that trying to run dual ECM's (one per bank as BMW do). This way i can ditch every part of the petrol system including the tank.

I should be able to get control of the sparks with a Vems and dual EDIS6 arrangement, this engine already has a 60-2 trigger and twin pickups 60* apart, which is a massive help.

Tailwind, it's only being done to push the boundaries a little, it does of course mean a 2jz at 2" shorter would also fit.... that would be the big power weapon of choice.

Where do you plan on driving this thing? My gosh, take a trip to the Autobanh and rip that sucker up. I can imagine that you'd need some seriously wide and sticky tires to handle the power.

It actually won't be that powerful in the scheme of things you know, a well sorted 3s-gte will stomp all over it, only building it to say we did.

IC so essentially, you're a mythbuster of engine swaps?

Are you under 5' tall? The Audi V8 swap had cabin intrusion and that motor was what, 20" long? That engine has to be 10" longer?

Yep the audi V8 was a lot shorter, but remember it was fitted to a Mk1, this engine is going into a Mk2, we have much more room between the rear hub centre and seat back to play with. Also i'm not using the same transmission as before, i can save 7" of length by using Audi's 2010 A4 unit which has the output shafts right at the flywheel face.

It'll fit, we've been here before.
