Just caught this over on MotoIQ, a hayabusa engine + 96 miata.

http://www.motoiq.com/magazine_articles/articletype/articleview/articleid/1519/project-miatabusa-part-1-what-the-hell-we-are-thinking.aspx

And they are going to sell the adapter/subframe setup so we can make them too. It'll probably cost an arm and a leg, but damn thats one fun swap.

The miata alone was a score, a 96' that was in decent shape for $1500? And now endless rpm fun like in a honda?

Will it have reverse?

MotoIQ is fast becoming one of my favorite websites.

And yeah, it'll have reverse. They're taking advantage of the reduction gear between the crankshaft and the transmission input shaft to adapt the transmission input shaft directly to the Miata clutch.

I've thought about doing this for a while. I think it's got potential if you can get the car light enough. I'd run the bike transmission and screw reverse though.

Can someone remind me what torque at what rpms the 'busa 1.3L makes? That's the big thing I keep thinking of every time I see one of these swaps.

Of course, if I ever win the lotto, I want to swap one of the 'busa V8s into a hachi

A stock 03 Busa makes 175hp at 9800 revs and 101 ft-lbs of torque at 7000.

I wonder if they'll have to dry sump it? Tha'ts a big additional cost.

Most Se7en and other kit car guys inthe UK say yoy have to dry sump the Busa or it'll die. There are more forgiving engines for BEC applications.

IMO bike motors just don't have enough power to push cars like they should. I remember seeing a geo metro a few years back on this board that had a busa motor. The thing wasn't that fast. It spent most of the time on the track SCREAMING because the motor was working really hard in high rpms.

You should hear it. It's an oddfire, so you get a double whammy of aural awesomeness.

Agreed. As light as the Miata is, it's not that light when pushed by 100 ft-lbs. Bike-powered Locosts are down around 1000 lbs, which is what it takes to really make a bike engine perform.

$30K for the engine, $15K for the sequential tranny... I can't go there.
