Turbo for my KZ1000

It's common on drag bikes.
Here's a pic of mine..

What happened to Mr Turbo? The site is still up. I'll call the rebuild place tomorrow to see if they can give some info on sizes. Your probably right About an F40 as it came off a 82 KZ1000. Mine drags some and will not coast at all. I also have a list of parts for the S&S Super B carb. Chris

Hahahahah The site I saw is in Capetown South Africa!! My apologies.

Zed. Is that a Kosman frame ?

You can compare Zeds frame to mine ( My teams )
Here are two examples from my racing days
Although rebuilding the turbo is a great idea , It may be OK.
Turbos do not spin super easy . Not much free wheeling . Takes real exhaust power to make them spin and build boost


THESE ARE BOTH Kosman chassis

Yes! It's a Kosman frame.

Any advice on a re-builder for my spare head? Also if I take the Turbo apart for inspection what should I look for as far as indications of NO-GO? I also need help on the way the Impulse line is connected to the waste gate and such. Thanks Chris

You're welcome, Chris. You're getting a lot of good advice here. A lot of KZ knowledge on this website!

Also, some more food for thought - I think that with a "draw- through" system (carb mounted at turbo inlet) you're going to be limited to mounting the turbo behind the motor. The setups that you might see on other bikes with the turbo mounted out front are all using "blow-through" setups that use fuel injection - no carb. If you mount a draw-through up front, you'll get a lot of fuel/air mixture separation by the time it makes it's way to the inlet manifold.

For this same reason of fuel separation, I've never seen an intercooler used on a draw-through system. If I'm wrong, somebody please correct me. Just my .02.

Thanks Mike, that's good to know and makes perfect sense. I've got plenty of room behind the head so I'll try to make good use of it. Chris

You can't use an intercooler on the draw through.
You could mount the turbo up front and convert to blow through which would mean using a modified bank of carbs with pitot tubes to pressurize the float bowls but i'd just keep it simple as a draw through and use what you have.

This might help

That BHP waste gate is capable of being setup as a multi-stage unit. The screw on the end will set your basic level of boost. The airline fitting on the side, at the top, is where you feed in additional air pressure (from a remote air reservoir) to add to the spring pressure on your waste gate valve, thereby increasing boost. The other little fitting coming off on the side, closer to where the 'gate bolts on to the exhaust system, is just a vent, I *think*. To keep things simple, you can just run a fixed level of boost. Hope this helps.

Thanks for the insight guys. I'll be starting with about 5 PSI of boost, and see how hairy it is. Also that FAQ was interesting,and the polishing too. I figured it couldn't hurt to polish the housing scrolls internally. I've got a long way to go before I get this to a running stage. I'll keep ya updated. Thanks Chris
