Our latest project has been the development of a turbo Renesis engine for our Redline Time Attack RX-8.
We have designed and built a new manifold and downpipe, and will utilize a Turbosmart wastegate and Turbonetics T4 turbo.
The Renesis has been machined here at Mazdatrix for the oversize stud kit that we sell. The stock rotors have had the apex seal grooves EDM’d to accept the taller and stronger 86-95 style apex seals. We will be using ceramic seals, and the rotors have also been side cut for extra clearance that is preferable in highly stressed engines.
The plan is for the engine to be on the dyno in the next couple of weeks - we will be busy this week with the Formula Drift finale at Irwindale Speedway - and then we will be on track in October 23-24 at Infineon Raceway for Redline Time Attack.
We have posted photos of the engine here: http://www.mazdatrixracing.com/?p=394

Someone here in Greece did that already, I think last year but eventually broke for some reason.

If you're referring to the red engine, it doesn't have 6-port end housings. At least not in that pic.

TeamRx8, you're right about that-never noticed that! The original thread is about another car and engine. The r&b one pictured is actually using engine parts from the Challenge model which is 4port and 192hp. Good eye!

Man I always had this idea and was waiting for someone to do it!! Now how about a semi-peripheral intake as well?
I wonder how this setup would do aspirated with a properly designed aspirated exhaust header....

i feel somewhat vindicated
I started a thread about adding the P port to the renasis and it was shot down.
Old news.
Very, very, sweet, sick and solid looking engine you got there dudes!
Adding a steel part to the upper part of the MM? Did you fill the insides with hockey pucks?
Those 3" header pipes??
Use rx7 rotors?
power goal range estimate?
Stay away from 9K without more eshaft and rotor work?
Water meth is your friend--can you use it? Even just water will help--right?
Sorry--too many questions--i just get excited seeing that damn thing!
Really nice.

We just posted a few more detail shots of the studded race engine as it went together on our blog.
We are going to be running 14 psi with this setup.

Hey, is there any specific reason as to why you used 84-85 7 housings as opposed to later FD housings? Timing issues or something else? I'm thinking of building an engine like this since I have all the parts just laying around, but I have 13bre housings.

Because you would have to machine coolant seal grooves in your housings
You may want to learn a whole lot more before tackling such a project. Note that nothing has been proven yet. I'm not even talking basics like understanding what basic parts work together but stuff like custom fabrication, aftermarket ecu system, heavy financial burden, etc.
In the end, whether there's any benefit to doing this rather than blocking/filling the side exults ports, or even just doing a 13B 6-port conversion instead, remains to be seen. I'm not even informed enough to come up with those questions myself. They came up during a discussion with another notable engine builder that doesn't consider the Renesis to be the best choice for high output FI ... that said he didn't knock the project, but was interested in the results.

What we have seen in our market is most customers seem to want to assemble their own turbo kit, so we will be offering all the parts needed to make a system. Manifold(s) will be built and the customer then specifies what turbo flange they want welded on, what waste gate flange, is it blowing back into the downpipe or to the atmosphere, 3" or 2.5" downpipe, etc. We have the various injectors available now, as well as a line of Haltech computers.
So a customer can build their own system around our Renesis manifold. Of course, if they would rather us do the work, we can build an entire system in house here at Mazdatrix.
