they are not using the hayabusa transmission.

 

He is just proving again (in the same thread) that the reading comprehension on this forum is quiet low.

 

I'm pretty sure Mr. y8s was being facetious as well.

 

Thats what I was thinking.

I'm just curious how the tranny will hold up to a motor turning 13,000 RPM. More heat, possibly have to make oil coolers for the tranny.

 

Reading comprehension fail, go click the link JKav posted and read.

and

 

i've read both articles and the website.

you guys haven't even read this thread--well except gospeedy

 

I only read the first link on the original post, not the second link.

So by that logic this adapter plate is restricting the speed to a managible 6,900 RPM as opposed to the higher 11,000+ what is the point of even doing it since your losing 3,000+ rotations.

So your motor works some 35+% harder than it should for the same output?

 

Umm...no

The adapter just mounts the motor to the Miata tranny, with the Hayabusa output shaft aligned with the Mazda input shaft.

They are using the stock Suzuki gear reduction on the output shaft. You still have the full rev range and powerband of the motor, but the multiplied torque is more useful for a car's weight, and they couldn't attach a flywheel to the 'Busa crank anyway, and they get a stronger gearset.

It's just a geared reduction to a secondary shaft...like you on a Friday night. ( aye keed, aye keed)

 

Plenty of small, lightweight V8s out there...

 

^^ haaaaaa.

I was meaning viable motors. The right answer is probably always the LS1, but the motor weighs about 470lbs, and there are certainly lighter motors from Audi, Bmw, Merc, and others that are production capacity and desirable in some rights. I was kinda thinking of the lightest4-cyl swap you could do and the busa is probably it. My genius *** was thinking Ecotec or some other light 4-cyl aluminum block, but ****, why not just an old air-cooled Vw magnesium block, there's your no power and ultimate weight reduction, huh?

On the other hand, you could put some of those little v8 motors in the passenger seat so you can say you have a V8 in the car.

 

Doesn't Kawasaki make like 1.5L sport bike motor now? Wonder what that dyno chart looks like.

Miatamike, you're on eggshells. Tread lightly.

 

They have a 1352cc in the ZX-14, comparable to a 'Busa. There is a supercharged 1500cc version of the old ZX-12 motor in their jet skis though...

Other than that the only 1.5Ls I can think of are V-twins.


Come on man, torque multiplication is a tough concept...it involves ratios...and fractions! ******* fractions

 

I skipped fractions and went straight to decimals.

 

I was referring to his admitted lack of reading. Unacceptable.

 

How about the Triumph Rocket motor?

More of a thumper than a screamer, (bikes wise, still redlines at 7000rpm)
2.3L 150ft/lb in-line 3.

Bolt on a Turbo/SC and you've got just over 200ft/lb

Fooook knows how much the motor weighs though.

 

Now with more equal length stainless steel turbo ready header:

 

That closeup just did it for me. I want!

 

i take back what I said by that close up as well... maybe boost will make up for what I hated. However, those V8 hyabusas are awesome shitz as well. Expensive tho.

 

Mmm sexy.

 

That thing is like a work of art. I want to hang it on my wall.
