Shane, Unless you plan to fly very conservatively, you will need to replace the stock turbo. Or as a few people have done get the unit modified to prevent overspeeding at high altitude. Several guys flying with the stack turbo have even REMOVED the waste gate valve entirely, (that's right just the holes), and they still have overspeeding and breakage. Typically the turbine self destructs and you lose boost but the plane is still flyable fortunately. Check the archives for some of the mods done to the stock turbo for aircraft longevity.

Thanks Ed,
I already have an old style 13B turboed engine that I am starting with, so that decision has been made. I also have a local guy that specializes in building rotary's for racing and he has done a couple of aircraft engines in the past. He is Adam of RX-7 Specialties.
Thanks again,
Shane Daly

Welcome aboard, Shane
A 13B turbo should make that Glasair really boogie. All questions are welcomed, responses are varied but, we do have folks with decades of rotary engine experience and real -world experience with the use of it in racing and aircraft. Data, opinions, rationale, facts, speculations, problems, challenges, wishes and hopes can all be found here, you're responsible for sorting them in to appropriate categories {:>).
I would say the first decision you need to make about the engine is whether to go with the newer Rensesis 13B or the older Rx-7 13B. If you want turbo, the Renesis does not currently (but rumors abound about a future Forced Induction Renesis) come configured for one - although, it is certainly possible to roll your own turbo version. Members of the list have found that for the most part the stock automobile turbo which is designed for short power bursts does not do well in aircraft application (although with very low boost levels, some have had success). So a different turbo package would likely be the smart thing in any case. Plenty of older 13B's around but of course the parts availability down the road will probably start to decrease. Both the older 13B and Renesis appear to work equally well - with the Renesis giving a bit more power.
Just one of the many design decisions you will face.
So, again welcome to the list.
Best Regards
Ed

Hi all,
I am new to the list just getting started on a 13B turbo conversion I plan to put into a Glasair 1TD that I am also just starting to build. I have built a few fast glass aircraft in the past, so I have no issues with putting the Glasair together, but I am green when it comes to building up a rotary. I hope you don't mind a few newbie questions once in a while? I have gone through the archives and there is a lot of great info there, so that is where I will start. I look forward to getting to know both the engine and the community as I progress.
