Renesis and boost.
I remember reading an article over at RN where one of the guys commented that the Renesis was specificly built to take boost. I'm wondering if anyone has any more specific info on the subject.

I believe what was intended that the Renesis was meant to take 'a boost' in power... I would gather that the engine has been detuned from the original 280 hp spec, probbaly for price and also emissions/mileage.
Even by Mazda's chief rotary engineer the next gen RX-7 would in his opinion, be better off without a turbo and instead by increasing the rotor width instead. Couple that with a lighter weight, the RX-7 is going to fly.
But as per the likelihood of a super/turbo charger, it's yet to be seen. By most admissions the engine is very compact and the required plumbing would be a tight fit (but not impossible).
I think we need to hold out and wait for aftermarket items rght now... nobody's sure at this point.

The word "boost" used by a RX-7 enthusiast in that sense always means forced induction. It sounds like the Mazda guy informed the RN guy that the RENESIS could handle FI, which the RN guy then referred to "boost" in the article.
It only makes sense that Mazda would keep their bases covered on the boost issue, there are many reasons such as:
- Turbos are actually increasing in popularity, maybe there will be a demand for a Turbo rotary sometime in the future
- Racing applications
- Enthusiast appeal, many people like being able to add more power to their engines
I still think the next RX-7 should come in 1.5L NA and and 1.5L turbo variants. The NA should edge out a 911 in every measurable category, and the Turbo would be Mazda's worldbeater, competing with cars like the Ferrari, NSX, and 911 Turbo for a fraction of the price.

... the big question will be, IF there is a 1.5L RET in the next RX-7, would that fraction of a price be 14/15ths??
ahahaha...NEVER!! :D
