Any feedback on turbo normalizers that have been placed on the 4 bangers
for the E,F, or 201?
Heard that the 6 cylinder engines were made for the turbo and many
problems have occurred with
trying to put them on the 4 cylinder engines.
Also heard that they Ray Jay turbo is more problematic then the newer
turbo made for mooneys (m20 turbo)?

It was not my intention to suggest HOW to fly the airplane, just that it was extra cost and complexity unless you DO fly over 10K on a regular basis. If the original poster plans on flying above 10K regularly, then by all means he should get a turbo or turbo-normalized airplane, regardless of where in the country that flying is done. But, as you well know, below 10K, the turbo doesn't do much for performance and adds a lot of cost and complexity that may not be needed if he is not planning on going to oxygen altitudes routinely.

I'm all for flying higher to get above the weather and traffic and turbulence, or to get better true airspeeds, etc. However, I hate the cannulae (cannuluses?), so I don't generally get above 10K unless in something pressurized. Again, no implication meant, just a suggestion to look at projected use of the airplane before taking the turbo leap.
