What kind of trike? Traditional layout, or 'reverse'? What weight are you aiming for?

Do you have a 'style' in mind?

reverse trike , bit like a morgan but i want it to be aerodynamically efficient so it may be a bit narrow.

100 mph top speed would be fine / 50 mpg is a goal .

Pedals! I had them on my trike before I learned how to ride a proper bike.

Only joking guys. How about something shaft drive? It seems logical to me if you are building a conventional trike/reverse trike.

i did specify shaft/chain drive !!!

i was thinking something like a sidecar , but completely faired in , but that would mean doing my bike licence unless somebody else knows different

Moto Guzzi V Twin, the idea of a guzzi morgan look alike is etched on the back of my brain, guess it won't go away till I try it...

Even thinking of ways to incoperate a car gearbox for a reverse...

Why not do a bike conversion i was a trike builder for 5 years at the trike shop in Cardiff and used to do all the shows and see a lot of crap but if car engine one is what you want then good luck seen a Subaru engine trike was nice.

If I was building a front engined trike, then I'd make it front wheel drive. Air cooled V-twin hanging out the front... coupled straight onto an LSD.

(Ps - I know it's not what you want ).

The best place to fit an engine is just infront of the front axle. Ideally it would have a very low centre of gravity, so a boxer engine is best. Porsche, Subary, VW beetle or 2CV spring to mind. Erm, or a scooter engine. A Vee engine would be the next best. Plenty of V twins on bikes, or a V4 from a Pan European.

so the BMW boxer isnt a good engine ?

i thought of something like the oekmobil , but with two wheels on the front , but that design would lend itslef better to a rear engine trike , and would be far simpler to build .

its also more difficult to fit two people in .

BMW Boxer is a very good engine... particularly if you're definitely going front-engine and rear wheel drive (pic attached of mine showing the gearbox and prop).

Must I really quote every boxer engine in existence? I believe Paxton bus engines are boxers. Fancy one of them? Plenty of low down grunt.
