Thanks BigC, for the effort to initialize and maintain this thread. I'm hoping to revive the spirit in my '04 and this thread gives me two good starting points.

Kevin did my rebuild in June and I haven't had a single hiccup out of the engine. Matter of fact, while he had it he fixed a couple of suspension problems for me and replaced a worn clutch. Great guy and his work is immaculate!

I will also add that people should educate themselves on what is important in engine building, and a lot of the attention to detail you see in piston engine builders does cross over to quality rotary builders. There is also a lot of misinformation regarding what makes power, and what doesn't. For example, the proven high HP drummond engines are not ported.

People who specialize in earlier rotary engines may not be the best choice for a Renesis. It has some of it's own unique peculiarities that require knowledge and experience on how to best address them.

Expectations management is a critical contributor to happiness.

Have a long conversation with your rebuilder and make sure you understand what to expect after the rebuilt engine is broken in. If possible, get any warranty terms in writing.

But, one and IMO the best, would be Darryl Drummond. He built the sealed Renesis engines used in the Star Mazda Formula Race Cars and a buddies Renesis from him made 268HP on the engine dyno.

just FYI that Daryl is now mostly retired with the exception of a certain few past customers. IMO he is a legend for Renesis race engine work and knowledge. 50+ years of rotary engine experience and well known in racing circles, his influence and race engine work places him in an upper echelon of a very few, rare individuals.

Much appreciated.

I can't seem to find a thread with a substantial number of reputable rebuilders, so I thought I would post the ones I've seen referenced on our forum.

Locations and reviews may help new members, and save time for the rest of us.

To summarize here too...

Bro, I said Mazda Motorsports does that... not Tasca.

Mazda Motorsports can sell NEW engines... or rebuilt engines but they can't give you the core charge back for the rebuilt engines.

Tasca can only sell rebuilt engines and they will give you the core charge back.
