Silly title I know but does anyone know how doable it is to graft a Harley motor into a small car such as a Miata? I know the Morgan 3 uses a Mazda transmission to mate to the SandS motor. Anyone know how they hook this up?

Thanks a lot.

 

Lots and lots of cutting, bending, welding, grinding, mill work and lathe work.

Be sure to post pics as you go.

I knew some guys 25 years ago who dropped a Mazda rotary into a Triumph Spitfire. It was a cool project.

An air-cooled MoCo thumper into a Miata? Don't see why you would, but I'd love to see you do it.

 

I know the guys who race 'midget' cars use Suzuki bike engines in their builds...b.

 

Anything is doable. As always it is a question of time available, skills + tools and $$$.

There are kit cars that use Harley engines. It would probably be the coolest way to do it IMO. Google "Harley kit car" and you get some interesting results:

If I were to do a conversion an existing car, Miata or Porsche 924/944 would be ideal from a weight perspective. The 924 could be interesting since it has a rear mounted trans, so yo may end up with a rear weight bias! But it doesn't really fit the personality of those cars though, IMO.

 

There have been many bike engine-powered cars over the years.

And plenty of car engines on motorcycles too!

 

My dad, in the late 60s, raced 1/4 mile timed track on a bike with a car motor in it (dont recall what kind). He said it would seize up if they didnt shut it down, as they had no cooling system

 

I'd rather drop a small block V8 into a Mazda. Why put in a smaller motor when you can have a V8?

 

Cooling it would be a challenge, unless you hang it out front like the bike-engined Morgans, or mount a hp-robbing electric fan.

 

Here ya go ..
