I'm looking for a all ali engine 4 cyl. about 1800cc max, normal aspirated, carburator single overhead valves. it's for a kit project..any ideas for a donor ??

Why carbs?.

Subaru, or retro modified K series, Millington block ford unit.

Duratec is the obvious choice, but again, why on Carbs ?



ETA - didnt read post proprly - duratec is OBVIOUSLY not SOHC

Then you need roller barrel TBs

Do you mean single overhead cam? The Rover K series comes with an SOHC, 2 valve head on the economy models (only in 1.1 and 1.4 capacities though).

Some of the Honda D series engines were SOHC, they do turn backwards though!

The engine is going into a replica Bugatti, I think Carbs will look just a little better than Injection, no other reason..
Thanks.

The Ford Puma 1.7L engine is an all aluminium affair and puts out about 135Bhp, plenty of them knocking around in breaker yards. Also the 1.4 and 1.6 FORD ZETEC SE engines are also all alloy engines too.

Twin HS6's get some Brass dashpots and screws made up.

You'll struggle to get a pushrod Ali engine.

SOHC the only thing really as has been said is the Honda, but they spin the wrong way for 99% of Front-rear drive apps

The Zetecs are all DOHC though.

Why all ali 4 pot?

For authenticity, you'd be better off with a relatively long-stroke design. The old Triumph Straight 6 has a nice, Bugatti-like 'monoblock' appearance and SU carbs?

[choogh]

The Bugatti type 37 was/is a 4pot all ali engine with sohc and 1400cc, they made a supercharged version for the type 37a, but a simple 4 pot will do. It's possible to have a new-old engine fabricated by Brineton Engineering, exact as the original, but at £17k plus, it's way out of my league. Gearboxs a snip at £7k.
No.. donar car for me..

Fair enough, though I'm struggling to think of an engine that meets all your criteria - SOHC and expensive alloy construction don't often go together.

As others have said, there's the SOHC variants of the K-series. The only other fairly readily available angine that springs to mind is the Imp/Talbot Horizon (bit small at 875/930cc?).In any case, they are hardly going to be 'authentic' in other respects; the Bugatti was basically carved out of a rectangular block or alloy, whereas any modern alloy engine block is going to be cast, with stiffening ribs and webs all over, looking very different. As perviously mentioned, they are also going to be to short stroke and revvy to give the right 'feel' for a Bugatti rep when drivng. I'd still be inclined to suggest you'd be better with an old British with longer stroke, regardless of the block material and valvegear - Triumph, B-series or whatever.

Or there are the longer stroke variants of the Alfa Twin Cam; all alloy and very much 'classic' characteristics, but DOHC?
