I may have VERY bad news for everyone. I went magazine shopping last night in prep for a trip back home and a meeting with the loacal rotorheads. So I picked up RE Rotary magazine, RX-7 Magaine and Options 2. in one of them I saw an article/section on the various turbos and superchargers under development or getting ready for release. Almost all talk about a 40-50ps increase, however, only post number of 260-270ps. This is making me think these "blowers" are for the 4 port engine only... 
On an up note... there are several ECU mods out... some at around 50,000 JPY. The JP ones offer rev limit cut and speed limit cut. Not to take sales from Canzoomer... rather to offer other choices and also more options for CZ to add to his unit...
MOre to come when I've had a chance to read the whole mag (as I'm heading on vacation soon, probably won't post into until the 20th).
Lightly skimming the articles... as far as the Blitz S/C goes... "Blitz' power target is at least 260ps. In writing this you might think "this is only a 10ps increase over normal," but Blitz tests resulted in an output of around 180ps from the RX-8. So 180ps is the starting point. Adding the compressor kit can be then expected to be normal output + 80ps." It seems that BLitz is expecting it to fall in the neighborhood of 450,000 JPY.
Knight Sports has a turbo kit coming up for about 400,000 JPY give or take. Power output... with 0.3 kg/cm3 of boost, 35-40ps. I'll go on sale in another 2-3 months.

From the standpoint that a lower compression ratio can take a higher level of boost I absolutely agree. There are actually 2 different compression ratios in an engine. The first if the actual compression ratio. This is the number that everyone knows and it is 10.0:1 in the Renesis. The second is the effective compression ratio. This is based on a combination of how much air gets in the engine as well as the actual compression ratio. Obviously if you add boost to the engine you have more air in it. More air gets squished and the effective compression ratio is greater than the actual compression ratio. On a naturally aspirated car you are generally lower than the actual until you hit or exceed 100% efficiency. A turbo easily does this.
There are a couple ways of looking at this. Higher compression ratio (actual) with low boost can actually be the same as a lower compression ratio (actual) with higher boost. There will inevitably come a point at a certain level of power where the lower compression ratio and higher boost will make more power because it can run more advanced timing but this is somewhere over the 400 rwhp mark. At least it was on the older rotaries but you get the point.
There is also another point to consider. The total port timing will also play a role in the effective compression ratio. The longer the ports are open, the more time a turbo or supercharger has to force more air into the engine. So based on this we can see that the 4 port Renesis can actually handle more boost than the 6 port Renesis solely based off the fact that less air can enter the engine for every revolution. It is the total amount of air entering the engine in cfm that determines the effective compression ratio. How much pressure it is under to get to this point is irrelevant. The big issue with more boost though is that it heats up the air more. There is always a tradeoff. For a street car I would favor high compression and lower boost.

About it only being for the 4 port because they mention the 210 PS number: that 210 PS is probably the wheel horse power. I'm looking at the dyno of the greddy and the power falls off at 9000 rpm like the 6 port

Taking some time to read the articles now... there are several kits under development...
Blitz supercharger
"Blitz' power target is at least 260ps. In writing this you might think "this is only a 10ps increase over normal," but Blitz tests resulted in an output of around 180ps from the RX-8. So 180ps is the starting point. Adding the compressor kit can be then expected to be normal output + 80ps." It seems that BLitz is expecting it to fall in the neighborhood of 450,000 JPY.
Knight Sports Supercharger
Supercharger kit (not turbo as I said earlier)coming up for about 400,000 JPY give or take. Power output... with 0.3 kg/cm3 of boost, 35-40ps. I'll go on sale in another 2-3 months.
Greddy Turbine Kit Trust
Using a Trust T618Z turbo running at 0.5K boost the engine puts out 268ps at 7100rpm, max torque of 30.8kg*m at 5300rpm. Runs on an emanage.
R Magic NX System
putting out about 262ps and 28kg*m of torque.
Phoenix Power
Using a Trust turbo at 0.8kg boost. Good for between 340 and 380ps. Presently they don't have a prope computer for making settings or polling data.
RE Amemiya
Essentially using the Greddy kit for the turbo on an AT show car.
- Still more to come....

Wow. Do you know any more about the Phoenix Power kit? Im assuming the others are at the wheels and that one is bhp, but its still quite a bit more power than the others.

BTW... it seems that the Japanese are complaining about the car not feeling like it's living up to the claimed 250ps and that gas mileage isn't what they expected either.
