I have this weed eater that has a 4 cycle motor on it. When I start it up, I marvel at how it has a low throaty rumble when I start it. The thing has surprisingly good throttle response when you pull the trigger too.

But you know what? It is still a ******* weed eater.

Have you considered swapping the head from the weed eater onto your Miata?

Nope, you're right. I've never seen a boosted SOHC Mazda motor.


Also: *****.

I can only think of one Honda setup where you put a DOHC head on a SOHC block and that is when you put an H22 head on an F22/F23 block. This gives you more power stock for stock, but in overall potential the F22 head is far superior because it has a better combustion chamber and more meat in the head for larger valves and ports.
People frequently confuse aggressive cam profiles with a head being good. VTEC is just a cam profile. A non-VTEC head can do the same thing, it will just get bad gas mileage and not idle very smoothly.

There is not much inherently wrong with SOHC other than a lack of ajustability in the cam profiles and the fact that the spark-plugs cannot be perfectly centered and vertical.

2 valves per cylinder is what makes this a lame head.

I would personally love to experiment with the 16v sohc head in a Miata.

Too late, someone has already done a 3 cylinder SOHC. He is more different and rad than you. Now you either need a 2 cyl SOHC, 2 stroke, or maybe you could put a a V4? All super rad and different.

Sometimes there's a very very good reason why no one has never done something before.....

Where is that dude that put the 2 stroke snowmobile engine in his Lemons Miata? I believe it had a pull start sticking out from the "hood"

Edit: I assume it was 2 stroke based on the smoke plume and exhaust note.

Someones got to make a giant 1 or 2 cylinder engine, no? That will be very rad.

A square looking motor would be sick under the miata hood.

You can still be different

But fitting the exhaust would be ehm... challenging.

Nothing wrong with frankenengines, but make sure it's fun for you own sake and not for others.
