Hayabusa motor?

screaming6 · 08-06-2011, 10:40 PM

So Ive contemplated many motor swaps in the coming years and one that always draws my attention is the Hayabusa motor in small light weight cars. but i have never seen one in a Miata. What you guys think

Granted there is pretty much no torque but some nitrous or a turbo could fix that I have seen some from conservative 350hp up to about 600hp+

although stock
99-07 171.1 hp 93.4 ft-lb torque

08-09 197hp 102ft-lb torque

Aren't they matted up to the stock tranny though?

Ben/brg · 08-06-2011, 11:54 PM

I've thought about this as well. There must be a reason why it hasn't been done before though..

I thought this one had been beaten to death. The conclusion is that for the same money one could put in an LS drivetrain, have more hp and torque available, and be infinitely more reliable.

I tell my junior engineers this: Just because you can think of something doesn't mean that it's a good idea.

You say that as if there is one answer to the engine swap question.

As far as "less money", the MotoIQ boys have demonstrated that, so far, the ability to use the stock transmission with the motor will significantly reduce fabrication dollars and reduce the number of parts you need to replace to make the swap work. Also, it's lower HP means that you won't need to change out axles or brakes either.

Different strokes for different folks.

RedemPhex · 08-12-2011, 09:18 PM

This idea isn't that bad really, but as has been stated already its heavily dependent on what transmission will get used.

Plus, there is a lot of advantages to this, including a significant weight loss compared to dropping an LSx in. Don't get me wrong, I would love an LSx, but I can't help but believe that the busa motor is more at "home" with the miata's lightweight theme.

rugger · 08-12-2011, 09:38 PM

I'm probably the minority in thinking the swap is a waste. For God's sake and mine somebody please do this swap so that we can quit talking about it.

I'm pretty sure that one ride in a 400+ ftlb powered 2500 lb miata would change your opinion.

oh I love it! I am not ragging on the LSx swaps. But a 200hp 12k rpm 1900 lb miata sounds good too.

All I am saying is:

Less weight = Miata philosophy*

*except when you double the power and only add 150 lbs.

Not you too!

I'd love to have the $20K it would take to build it. I don't recall if the site listed numbers on that v8. Anyone know hp/tq of that thing?

DazedAndConfused · 08-16-2011, 12:44 AM

75° odd fire V8
2.8 LITER, 170 cu. in. displacement (3.0 liter optional)
84mm Bore X 63mm Stroke (67 stroke optional)
4 cams, 32 valves via internal silent chain
530mm wide x 485mm long x 530mm high
400HP @ 10,000 rpm with stock street cams (higher spec. is available)
245 ft-lbs torque @ 7500 rpm
200 lbs engine weight
Billet nitrided steel 180° crank
4340 H-beam con-rods with ARP bolts
Billet 6061-T6 aluminum crankcase
Dry sump 0il system with 4 stage pump
7.25" or 5.5" Twin disc clutch
DTA S80 full sequential ECU
Unique cylinder offset and cam drive arrangement yields a compact design- Patent No. 7,168,405

(I believe the one they put into the Ariel Atom was 500hp)

Alex has been lazy about updating that page, that's all. All the up-to-date shizzle is right here:

http://www.motoiq.com/projects/proje...miatabusa.aspx

The car is very, very close to running. We actually cranked it last week, but the starter is having some problems and needs to come out. Taking a 1 week break for a quick LeMons race at Sears Point, then we're planning to try bump starting it.

As for the logic of this swap vs. a turbo or vs. an LS, there is no logic, there is only awesome. Lots and lots of awesome.

http://hardlinecrawlers.com/forums/i...p?topic=7265.0 the first pic shows how this guy mated a gsxr engine to a samurai trans (i used to build samis and talked to him a few times) he used the stock gsxr clutch/trans and just welded a bar off the sprocket and splined it to the input shaft , he had to run dual shifters but in a miata not needing the reduction you could probably just do the same thing either straight to the rear end and sacrifice reverse or figure out which gear to leave the busa engine in and run the stock miata trans... maybe even run 2 shifters like he did and just make up for the lack of torque using the stock trans as well as the shifter for the stock busa trans just an idea /:

Ric · 11-30-2011, 10:04 PM

I did a track day back in 2010 with someone who used a 1999 Swift 010.c with an R1 engine. He used both transmissions and simply put the bike in what gear he wanted and used the trans in the car to shift like normal. Of course the layouts are drastically different, but it is a pretty nice idea.
edit:
Here is a pic from the event.

Lime-Light · 12-01-2011, 02:00 PM

Interesting idea, using 2 transmissions...Sort of crazy, but how well did it work?

Ric · 12-01-2011, 04:58 PM

I believe it went well until the motor couldnt develop the torque to push past the down force at 100mph or so if I remember well.
