Nice! I've seen the A series / BMW head before, but never a turbo version!

That's quite steep though, especially as you need a turbo on top!

Do I read the correclty? An A series block with BMW bike engine head?

How do they manage to fit that? Water and oil way align? Bolt holes align??? That sound lucky or is the head not water cooled?

Sounds like a god projectif you have a Mini or a Midget (the car that is, not a very short person).

So a BCEC or CBEC?

I've seen that combo before but hell's bells that's a lot of money for a 8.5 CR engine that will make diddly squat power unless you source a turbo and do even more work on it!!

how do these things just happen to work out?! i still find it amazing that you can fit ford gearboxes to vauxhall engines, but BMW bike heads on a A+ block!?

BMW made a version of the Austin 7 under license. Maybe the K series bike engine can trace its roots back to an A series engine some how.

If I had £9000 to spend building an engine, I bet I could come up with something better than that though. I'd probably start with a V10 of some description and balance it to rev high.

It's a reasonably popular conversion, though it's quite involved. Some of the studs and coolant passages line up, others need to be blanked off and redrilled, and of course you have to sort the cam drive out. There are now conversion kits available to make this easier.

Some pictures of an early conversion, and a forum with lots of info for anyone interested.

K series so called as it comes from the word Kettle! Used to boil water

for half that money you could get a proper sounding v8 that'll last ten times as long as that tiny thrashed to death lump

Do the BMW K series bikes have a reputation for overheating then?

One of the reasons I gave up autograss racing, thats the sort of engine you find in 5 laps round a muddy field mini

autograss racing = poor mans motorsport, not.

chap i know has just finished one of these for a customer, normally aspirated, in 3rd gear at 70mph put your foot down and it'll spin the wheels forever, even with a slip diff!
