OMG and it's under 14.5psi!!!
Might be a little less by the time it gets delivered to my house but I've just bought two, one for each rotor!
Lots of money, race only engine. In this case 20b is your friend, or FI.

Both in the 300hp range, but technically no longer renesis engines, mostly older 13b with some renesis parts IIRC, I'll let the experts chime in since I don't know $h!T.

You can squeeze more than 230 at the wheels. Race teams have too many rules to follow, their results only attain to their specific series and rulebook.
The problem is mostly budget related though, are you willing to pay more than 15.000$ for an engine build? Would it be practical? Cost effective? reliable? Nah...

That said, I'm sure I'll get them all eventually... LoL Except porting of course.

I know that racing teams have rules to follow, but still... If it were that easy to get NA power out of the Renesis, racing teams would be able to get more. The plain fact is that porting doesn't give you worthwhile results for the cost, and NA mods aren't all that different.

You guys should look at some of their other products. They offer some great stuffs.
Ok, realizing that if such a thing were possible, that it wouldn't be steerable, legal, or have any redeeming qualities whatsoever, let's run the question, how would it have to happen? Since the OP ruled out increasing displacement with a 20B and also ruled out FI, that only leaves increasing the RPM of the horsepower peak.
The porting would have to be enlarged to an insane degree, while also testing the ports heavily on a flow bench, and the housings would have to be extensively modified to relocate the coolant jackets so that the ports could be extended enough. Additionally, the rotating assembly would have to be lightened to allow the horsepower peak to be increased from 8,500 to at least 11,500, assuming that torque at horsepower peak is common between the stock and modified engines (which isn't really a safe assumption; but for ease of calculation, I used that as a starting point). To be blunt, I think you'd have to rework the Renesis to work as a DKM instead of a KKM.
Could it be done? I think it possibly could, with an absolutely insane amount of money and a lot of time (a quarter million for R&D would be a good start; but probably wouldn't be enough).
Should it be done? Maybe by Mazda or someone else who could have a chance of recuperating their costs; but anyone else doing so would have taken the equivalent of climbing Everest to go across the street.
