GSXR vs Hayabusa DS conversion

An FZ1 engine is a better choice... Its almost identical to an R1 engine, but it has a heavier crank, and more torque.

Your thoughts? I am thinking Busa for the Torque and HP happens at lower RPM which can make it more dunable for me than having a High Reving Motor.
Hayabusa 2002-2007 check out the Torque and HP RPM.
Suzuki Hayabusa - Wikipedia, the free encyclopedia
153 HP Avg @9500RPM and 95 Ft/Lbs Avg Torque at 7350 RPM
GSX-R 2005-2006 makes the same number but a lot higher RPM
Suzuki GSX-R1000 - Wikipedia, the free encyclopedia
185 hp @ 12000 RPM <-at the crank No listing on Torque
Yamaha RfZ-1 2006 Way Lower Numbers
Yamaha YZF-R1 - Wikipedia, the free encyclopedia
180 HP @ 12,500RPM (Claimed at the Crank) 78·Ft/Lbs@ 10,500rpm (claimed)
134 hp <-- Rear Wheels
Yamaha FZ1 2006 and UP Check Out the HP and Torque #

Personally I would stick with one of the Zuki power plants. Not because its a better motor rather they just seem to fit/look better in the DS frame with minimal chopping compared to some other motors. A majority of the DS conversions out there today are using Suzuki power plants.
THe 1000 is going to be more than enough power for what you want to do. Yes the Busa will have more low end torque but it will also carry additional weight on the front wheels and have a tendency to plow. For duning I would give up the low end torque for a lighter front end any day. I don't think you would be kicking youself if you settled for the 1000 over the Busa.
BTW there is a really clean looking GSXR1000 conversion that just went up for sale over on "the other" forum. With all the little details needed to get these things to run well sometimes its just better to bite the bullet and buy one that is already built by a reputable builder. THats what I did...

I don't remember... I'll weigh the engine the next time I build one. Right now, I'm doing a DS/CBR900RR conversion.
The biggest thing to remember when doing a conversion, is to spend the extra time and install the engine in the proper spot, so you wont have to extend the swing arm.

If you mount the engine too far back, (which a lot of ppl do, because it's MUCH easier) it will want to wheelie a lot. So, instead of re-mounting the engine in the proper spot, they simply extend the swingarm, to keep it from flipping over backwards when they hit the throttle. When I build my conversions, the center of the mass of the engine is within an inch of where the center of the weight of the stock DS650 engine was.

Just me thats Interesting , While charting with Bud on his conversions he brought up the same thing of engine location, thats why he said he likes to place the gas tank in the rear of the DS to even the weight out on the quad, so its not so nose heavy, yes that is some concern with using the Busa (Engine Weight) , but the way I look it it my wife made me a deal, I can have my conversion no questions asked, if I loose 50 lbs so hell its a trade off!
