turbo swap?
David (aka Big Cheese),
what is the part number on the turbos you put in that you call newer model, and where did you get them for 3500 each? Last time I overhauled either front or rear, it was well north of 5k...o a 3500 replacement, assuming similar perf or better, sounds awfully attractive. Also, was this a swap using 337 paperwork, or straight out certified via STC etc? Robert PS. Rear engine now getting close to 1400 hours, and burning through oil a bunch. Plus been thinking about bigger engines to go faster...so open to any ideas people have on this thread about overhaul, new, or straight out upgrade |

![]() So the turbocharger (Part no 406-970) was upgraded sometime in the past, circa 1998?
Then overhauled more recently 2011. That's 13 years. I can live with that. So the overhaul was about $3500 or so by 'Approved Turbo' in Vero Beach FL, as I recall. As with any turbo twin maintenance and cost.....it is all a blur...

engine options
1) Last time I had turbos overhauled (which is not too far back) it was well north of 6K each...I also used ATC, but maybe I didn't say the magic words?
![]() 2) no one has any comments on different engine options (other than just throw in another of the same)? |

Only other engine option I can think of other than the turbo-prop test mule would be Riley's 520 Super Sky Rocket. Probably cheaper to find one than convert one though. Brent |

I just thought I'd post that my Skymaster is through the annual and it went reasonably well. Engines seem to be all good with clean filters, good compression's, and scoping all cylinders yielded all "pretty" pictures of valves. Soooo, carry on I shall. Two factory engines installed in 1988 that now have about 1570 SFRM. Hoping for another good year.
Thanks, Ed |
