David,
the 7.5 is a very old model. Not sure if the differentials in the 7.5 can take the Sirio engine. It would also be difficult to find a clear body for the 7.5 as the side mud guard protection is wider than the standard 777. Himoto racing will have pre-painted bodies to fit the 7.5

I am currently racing a K-3 which is just a little more updated than a standard 7.5. It's still a good buggy, I am only having a little trouble getting it to steer as well as I'd like. Durability has not been any issue for me running an S7 and Werks B3. I am using a Parma body that fits most popular brands (except Losi) and it fits quite well and has that somewhat boxier look of the classic Kyosho's.

And why not ? Kyosho buggy diffs are known for their toughness.

On the KI & II you may have problems with the engine fitting the mounts if it's a long stroke. I don't remember off the top of my head if Kyosho started milling out the KIII chassis under the engine mount or not, but most aftermarket plates have this done. If your chassis is not milled and you have a long stroke, you can grind some on the chassis and the bottom of the crankcase to get it to fit, but avoid raising the engine to get it in there as it will raise the CG of the heaviest component on the chassis.

As far as the diffs in any of the 7.5 series cars, don't worry about them being up to a high output engine. Kyosho diffs have always been among the toughest in the industry. As far as that goes, the 7.5 K cars (especially the kI & II's) were the toughest cars going in their day. You really have to work to break one.

If you are looking for more steering from your 7.5 try an LSD diff in the front, put your steering links in the forward most hole in the steering link plate, and stand your front shocks up to maximize front droop. You can also use about 3 degrees per side of toe out which will give you excellent on power steering entering corners.

I hope the diffs are strong enough. They are identical to the 777. The Jammin, Hot Bodies cars/trucks, and Hyper 7/8 also use an almost exact copy of the 7.5 diff.

One thing you might try for more steering is the 777 front hub carriers. You can use the middle or outside hole for more on power steering. I'm not sure if you will want to use the 777 upper arm or get a longer turnbuckle to use those holes.

Nova Rossi 21BF.

Great mileage, excellent power for a buggy and sub $200.00.

And to the dude worried about the K2 diffs holding up...motors of that kind of power have been around for years. If they can handle the torque of a nasty .28 (which they have done for years in the Supermaxx line of trucks), they can easily handle the .21.

the k2 is a very good buggy. I think you can get a 3 port rb engine for around 179.00. Any yes the diffs are the same as the 777. a good driver can still wheel the k- series cars and win

You can switch some things around. I had an SP2 front end on my Kanai, everything but front shock tower and upper arms was SP2. Thing turned like a dream
