I see something wrong with this through.... it used to be, that car companies would overbuild cars for a safety margin, and then also try to make as much as possible, using the cheapest and easiest ways possible.
Hence, the reason we get 50+ HP from an exhaust on a Turbo II, and such huge gains from things like porting, etc. Now, cars seem like they are built to the very limit of the safety margin, with everything designed so well stock, that almost any mods don't really do much and aren't really worth it in terms of gains, etc.
Case in point the RX-8.... lol What I am afraid of, is that this engine will have the most optimized porting possible, and with the combo of "side-housing" intake, exhaust, and the fact that they are aluminum, will create MAJOR issues with detonation if this engine gets turbocharged. It will probably work great stock, but any extensive mods, and bam.
My theory: As the car makes power, the exhaust temperatures rise, and start to severely heat the aluminum side plates that the intake ports are going through.
This in turn heats up the intake air, making it more prone to detonation, and therefore, drastically decreases the reliability of the motor. By having larger displacement, it would only multiply the problem further.
There could be a huge discussion about this, and this is only a theory, and I'm also not quite an automotive engineer, so does anyone want to discuss and tell me their point of view?

Actually I believe there are still 4 injectors total... It just the secondary injectors have been moved onto the rotor housing. the primaries are still in the center plate runners... I also believe that they are trying to get away from turbos hence the larger displacement

if this engine makes a legit 280 horse power, then I don't see why you guys are complaining it's not turbo. The original FD only put out about 255 horse power. 280 horse power and the reliability of an NA in my fb = 
.
I'm sure it would only be a matter of time before someone makes a turbo kit for it anyway. Their are turbo kits for the current renesis for those that need more power

And what's wrong with cars coming with the "mods" you wanted to do anyways? If it's done it's done... does it really mater whether you do it or not? It's just a by-product of better design and manufacturing process.es
Anyways, I can't wait for more info.

All nice and stuff, but worthless if they want to sell any... I mean: 1.6 means 3.2 for taxes in Europe, so you can forget about selling any serious numbers overhere. Ok, we are not the only market but still... A 3.2 litre engine is above what people will pay for "only a Mazda" (I know, it's stupid, but many people want a stupid BMW or Mercedes, once we're in that price-league).
They should have gone the other way around: make it smaller! Most popular engine size (also for motorsports etc) would be around 2.0 litres, or a 10A sized engine. With modern technics, it should still be able to perform well, yet be in a good tax band, and be less thirsty.
Downsizing is the way forward

you would think that the aluminum sides would = easier heat transfer to
the coolant = cooler running?
