flat 4 sounds the nuts but tbh the BMW is the way to go!

I have stretched front end with 1299cc 4 pot and 5 speed gsa box. even with the stretched front end the bulkhead was modified. drive shafts are a real weak point with the flat 4 option.

when the supply of super shafts runs dry then ill use it as a garden ornament and fit a BMW engine!

Umm, Timmy...

Why not just use 2cv shafts? They're stronger than Ami Super shafts, and - since the LN box in Joolz' car is just a G box with different ratios - the situation'll be exactly the same there...

GS/A & Ami Super driveshafts = great paperweights!

Mind you, I gave mine some stick over the years and managed to break a gearbox the once with the driveshafts living to fight another day!

So is there any info around about what is required to fit a BMW engine?
I heard you can buy an adapter plate for the bellhousing but from where?
The Fuel injection is nice, but how does it go without a fan and cowling to direct air onto the heads, my guess is hot when sitting in traffic?

Cheers

Joolz car has 2cv shafts and Peugeot discs, with (I think) G calipers. Assuming his hangovers cleared up I think it's only fair he comes and tells us roughly what bits he used.

The BMW R-series 'Oilhead' engines are liquid cooled and require a radiator. I'm fairly sure they didn't have a fan fitted when on a bike.

I also am curious as to how they are fitted to a Citroen gearbox.

You need an adaptor plate made up, and I was too pissed to remember what Joolz told me he'd done with the clutch.

@Harley, I know you're reasonably competent in the engineering department, sit a BM engine next to a citroen box and its not difficult to work out. I know there is at least one other road going BMW powered car, a blue dutch one, I spoke to the owner at the world meeting and he was thinking about selling the adapter plates.

Re. Cooling. To be specific, the BMW R-series 'Oilhead' engines are Air and oil cooled and require an oil cooler. The bikes don't have an electric fan, however my car has a larger than standard oil cooler and a fan mounted on the back of it, like a radiator. I've also opened the triangular 'bonnet infill panels' to give more airflow through the engine bay. With this set-up it seems to cool fine, and sat at a fairly consistent 100 degrees C on the run up to Giel. The electric fan is only necessary when sat in traffic, but when needed does a good job of bringing the temperature back down again. I've not tested it through the summer yet, ambient temperatures are yet to reach the mid 20s.

i Just watched the Videos, bloody awesome !!

i'm trying to get the bits to fit 2cv shafts... either way, if i decide to fit a bike engine i'll already have a 5 speed box and plenty of space to play with
