Sunbeam engine users?

Hi all,

does anyone know of someone who is building or has built using a sunbeam engine?

Thanks in advance

They are slanted over a lot (like the pug engines) so I dont think they will fit in a locost.

Not the pushrod engines Adam - they are non crossflow OHV fours.

These engines fit in a westfield BTW - one hillclimbed up here quite succesfully a few years ago.

I was talking about the Lotus Sunbeam engine.

Which engine are we talking about? Not the 1725cc 1960's unit, it woud make a Pinto look like a microlite engine

The good old Holbay Hunter, I welded a few of those back together.

I know you were

I reckon (probably wrongly) that Brian is talking about the 1600 Pushrod job as found in Avenger Tigers and Sunbeam Ti.
I could show my complete Anorakhood by suggesting it's maybe better to go for a Brazilian block for more displacement, but it's maybe best if I shut up now

P.S. It's not Lotus Sunbeam - it's Sunbeam Lotus. Talbot Sunbeam Lotus

Hi Brian,

Can you give us some details of the engine?

For instance, is it 2l DOHC slanted over at 45deg.

I believe such an engine was used in the Talbot Sunbeam rally car in the 70's.

I might however, be barking up the wrong tree. It wouldn't be the first time.

The 1725 was a good bit lighter than a Pinto and coupled to one of the best gearboxes in the business, the H120 engined beast was pretty quick for its day.

I did consider using a Sunbeam 930 engine years back to build a sort of Lotus Seven S1 replica.

I think you must be thinking about those special alloy versions

The one I took out of a Sunbeam Rapier broke my chain block, and when it dropped on the floor, the effect on the earths rotation was such that it put the clocks back by 3 1/2 hours.

The block is the same size as a smart car, there is about 1 1/2" of cast steel between each piston bore, and when the engine is eventually removed from the car, the front end lifts by about 8" on the suspension. The water pump alone weighs more than a Pinto. The power output is 54BHP, not bad in 1961, a bit faster than the average horse, but never described as pretty quick!

Hi All sorry about the late reply,

was talking about the engine that zilspeed mentioned. i have a pal that used to run a sunbeam and has a short stroke crank lying about that he is looking to donate to a good home. some1 that will use it and not just punt it on.

Cheers

Short stroke could mean different things the UK but most likely it is for the 1300 version of Avenger/Sunbeam -- not a lot of call for those Ebay it.
