hey guys I know what you're thinking carbs on a barra? yes I would like to do an engine conversion on my 76 BMW 5 series and have decided I want to use a ford barra as they're in high circulation and im tired of hunting high and low for parts. but the catch is I want nothing to do with fuel injection.

so ive been told that as a start I need either an XR6 or dedicated gas motor. as theyre the same apart from the fuel system?

then I want to retro fit x3 48mm DCOE webers to it. and run electronic ignition. ( because I have to. ) I might have to run the motor at a slight angle but im not entirely sure untill I have the motor to play with positions. will with disrupt oil feed? the motor will slant towards the drivers side.

after the engine is in the car I can work on getting it tip top. but what would you guys recommend I do to the motor prior to installation.

cheers boys.

The height of the barra motor might be your first issue, then tilting it on it's side may cause issues with hydraulic lifters - but I'm no pro on that.

If anywhere in the world still sells carny engines it will be Merica. Why not a small block v8 with blower.

ive costed up an LS1 conversion for for that kind of money id rather build a BMW engine. plus the clearence for the headers isnt enough to clear the steering box.

and im not anti-boost im just pro N/A. its more satisfying building tough N/A car. im pretty set on 3 webers too. purely for the crazy fuel consumption, crappy reliability and the sound.. ohh the sound. the power and tourque figures to come from these carbies is pretty impressive also.

Are you going to run a custom inlet manifold? You could build one out of stainless exhaust tube and flanges for the webers.

Also webers are pretty pricey.

If it fits I would mount the motor at the angle it should be otherwise it's gonna be a hassle with sump, oil system etc, then you could graft a ford V8 bonnet bulge or similar for clearance .

One more thing though is I thought you had to run whatever emission system the motor came with, it's not the car age but the engine age so overall I'd stick with the EFI with after market computer it'll probably work out cheaper than the webers.
