We are building a helicopter and will be using a 13b with a TO4 turbo to get
a least 250 horsepower.  Can anyone recommend a brand of turbo and the part
number of the TO4 and related parts?

Paul, what turbo will you be using on your KIS Cruiser?

Richard

250 HP is a piece of cake with a TO4 on a 13B.
Especially if you can run the engine up to 8000 RPM.
Garret is the only company making the TO4 to my knowledge.
Who knows I could be wrong. I would specify an Inconel turbine
wheel and a water cooled bearing. Both options on TO4s.

As to trim, AR and so fourth I have no idea.

Chrissi, do we know what Greg is using?

You could also try sending email to Paul Yaw and asking him
what he recommends. yawpower@theriver.com

I am trying a stock 89 to 91 Mazda turbo. No guarantee that
it will work. A lot cheaper with water cooling, waste gate,
drain back plumbing and heat shields already to go.
