Has anyone tried to torbo one of these bikes before? If so, whats the cost of a kit thats compatable, and the name(s) if possible.

 

With enough money, you can do anything. However, I'd bet that an EX500 with a very, very efficient high-dollar turbo won't go as fast, last as long, be as safe, or cost as little as a ZX10R.
If you want a faster bike, buy a faster bike. (IMO.)

this engine is tapped for power from the factory. a turbo will turn it into a grenade.

 

Pasted from FOG from the ex--500.-com forum thread about installing turbos.:
******************
You haven't researched very well. I have repeatedly explained where the weakness are.. (FOG isn't exactly what you'd call friendly, courteous or even civil.)

#1 The two engine syndrome IE: the cam chain splits the engine in two. This causes the thing to warp and Twist to such an extent you cannot match up the head and Cylinders after disassembly with out re lapping their surfaces.

#2 the Crank. It's too long and has too many bearings because of the Two engine syndrome. Then to add insult to injury the hang the several pound lump of an alternator way out on the end. IE: they snap right behind the altinator....a lot.

#3 The rods are just simply too weak to support the current power output and if spun beyond 11,000 RPM the big ends will open and allow the bearings to spin. They also stretch and hit the head.

#4 The pistons, They are cast and very weak and will also crack and .... well you know.

#5 valves The rocker arm design (rather than shim under bucket) is archaic and so heavy a lot of inertia is stored in the valve train that the valves float off the cams easy and hit the pistons . again at speeds above 11,000 RPM.

#6 The cases They are so weak they can barley hold the oil. The rear output shaft of the transmission will often elongate the bearing bore at the drive sprocket to and oval so bad oil will leak out.

$7 The Balance shaft, Because its a vertical twin with a alternating crank a balance shaft is required to quell the fore aft motion of the engine due to the crank throws. this thing thrashes around inthere and often fails , especially at the waterpump derive end. It also sucks up power.

#8 oh crap that's enough.

In short a poor choice for turbo charging or hot rodding by any means. The factory alredey di all that can be done. The poor thing has been bored and strocked to within an inch of it's life. I think well beyound.

Is it a Bad engine? No, as long as it's left unmolested and run modestlly. I speak from vast experience in racing these things for 15 years and rebuilding many for other racers.
