Mine was from Autoexe ( http://autoexe.co.jp/SozaiTopPage/indexKinoubetsu.html ) and it just blown. All seals are good. Suspected something got into it and cause the damage. As I'm not in the country at the moment, so I hope my friend can snap a few pics of the engine pieces for me and let me upload here. But can't promise anything till I receive the email.

Would love that option if my engine fails, it would probably be cheaper to get a ported supersmooth engine from the US than to get it rebuilt here.
But I also wonder why there's no 3 rotor rennies. Isn't it like legos? :D

Rick has done a lot of port experimentation on these motors and can definitely provide that option. One of my issues with it is that the stock ports are HUGE already. These motors make 250 to 260 flywheel hp without port work and I've even heard of more. I hope to be introducing some really neat internals soon, like some new seals for the renny that people should find beneficial.
So yes, we can. More to come......

There's not much power to be gained but all in all some more reliability is always a plus if you have to pay from your pocket

he's a member https://www.rx8club.com/members/carl-h-43078/ look for his threads for videos.
but its a long way from just stacking it like leggos because of the port configurations
I believe that Charles R. Hill and rotarygod can understand what i mean. Then there are a couple of reliability mods that can be done, like working the oil inlets (do you call'em so?) etc.

The oil inlets and such are what they worked on first over there at MazMart. Rick Engman knows more about rotaries than just about everyone on the planet and he's the one doing the work. Paul is no slouch either
As far as not much power to be gained...Well if you consider that some have engine dyno'd the renesis at less than 220 stock and then there are modified NA rennies engine dynoing at 250-260 thats a difference of 30-40 hp at the crank. i think 40 extra at the crank is more than "not much"

Paul knows what you mean too.

Not because i don't trust the guys at Mazmart (how couldnt we all? ) but because of distance.The only 260hp-is ported renesis that i saw was a peripheral port one, have you got links to see simply ported side exhaust engines too? That might be really interesting! For what i recall Charles is putting down lower numbers at the wheels so i'm not sure of that conversion @ the crank.
Thank you for the infos anyway, i love these kind of threads!

The Renesis with completely stock internals that is well tuned running on high octane fuel (98 or higher) can hit about 230 rwhp or so max. Can being the keyword. That equals roughly 260 fwhp or so. The '09 engines for some reason have been reported to be capable of more.
What the engine "does" from the factory and what it "can do" are not the same thing. Paul knows good and well what that engine can do.

Still have no dyno figures on my stage 0.5 mild streetport Renesis. As you might know i'm am not the fastest guy when having a project engine (or header) to test
My project 300 hp Rensis is awaiting bigger secondary injectors and today came the long awaited Accufab 70 mm tb. I have my stainless dyno header finished and shall also black coat it with 1100 C ceramic. The Vi-Pec stand alone system shall be fitted and some other things But... i have 10 customer engines to do with 4 of them goin up on the Super flow dyno, so Renesis project will hopefully be dynoe'd in June I also have a customer Renny that has stage 0.5 streetport and 2 pin dowling for F.I in the future. The lower intake is also ported.It shall be compared with my stock port RX-8 and have same Unichip piggyback and 2.5" sport exhaust. Further plan is BHR ignition kit and E85

I thought you were referring to some work with stock internals. Thank you for the clarification!

Not much detail but hopefully more to come. This guy is ported with FI and has claimed to put down 368 whp. I requested more info so hopefully he responds soon

Well that might take less drivetrain losses into account too!
Anyway, something that i like about ported rennies is that the bevels (thank zoom44 for that term! ) on the ports, when present, help reduce side seals wear. Not too much but they do it.

the race rx8s, in the koni challenge, do about 250-260 @ the flywheel. they all have about 220-225whp.
which is what teamrx8 got as well. so yeah, that's totally possible without porting. teamrx8 did it with an intake, header and 3" exhaust. he even had a high flow cat.
