Renisses question
WTF is a Renisses i cant figure it out whats different about it, i hear that the ports are on different sides( witch makes no sence cause it wouldnt get as many strokes) an someone please explain!

i thought they moved the ehxaust port to the side, which eliminated all the excess ehxaust going into the intake air, i guess that helped a lot. they also redesigned the rotor or somthing, if you look at a picture, im sure its a lot lighter too.

they get 247hp. and i think 280 in japan, im not sure, thats what the book said. but the legal limit is 276 so i dont know. and it would rape the **** out of the tII. unless its heavy *** hell.

The Renesis engine's exhaust ports have been moved from the peripheral location to the side plates just like the intake ports. This location means the intake ports can be much bigger than before without any overlap, meaning much more power. The Renesis makes 247hp in all markets (less for autos) which is more than 50% up on their previous NA 13B, while still meeting all current and most future noise and pollution regs.
There are strong rumors circulating that Mazda are developing a new version of the Renesis with increased rotor width (the same way they went from 10A to 12A to 13B), which will make close to 280hp. If (and it's a big if) the RX-7 is reintroduced, this is the engine it will probably have. Mazda are still officially saying there will be no turbo.

Here's a lot of information
here
Just a small snippet...
Mazda began developing rotary technology in 1961, and since the late seventies has been the world's only rotary engine manufacturer to depend entirely on manufacturing technology and equipment developed in house. A good example is the Mazda Digital Innovation (MDI) project which allows the company to conduct virtual simulations of RENESIS manufacturing, maximizing the potential performance of the engine by enabling high precision and quality production engineering.
In 1994, Mazda introduced Total Productive Maintenance (TPM), the brainchild of the Japan Plant Maintenance Association, to its production lines. Thanks to TPM, Mazda has raised the efficiency of its production department and advanced the organization of its quality assurance and other key aspects of the manufacturing process.
Since 1996, the company has been pursuing what it calls the Mazda Digital Innovation (MDI) project, which involves integration of CAD/CAM systems from design through production. By employing the most advanced 3-D information systems, Mazda has revolutionized its entire research and development organization. In the case of the RENESIS project, Mazda used MDI to implement virtual simulations of machining processes in production engineering.
RENESIS is a naturally aspirated engine. It is both smaller and lighter in weight than the already compact 13B-REW. Owing to its reduced size and elimination of auxiliary equipment, the new power unit has a height of approximately 338 mm (13.3 in). In addition, the height of the oil pan is reduced to about half of that of a conventional design (approx 40 mm deep [1.6 in]),
Mazda engineers also used a supercomputer to conduct structural analyses aimed at reducing rib thickness in the engine's side housing and other locations without sacrificing rigidity.
WHAT'S IN A NAME? The RENESIS engine powering the Mazda RX-8 has its origins in the MSP-RE that was unveiled at the 1995 Tokyo Motor Show as the power unit for the RX-01 concept sports car. The name RENESIS was given to the engine in the 1999 iteration of the RX-EVOLV. Thereafter, RENE SIS, which stands for "the rotary engine's GENESIS," was carefully prepared for series production as the powerplant for the RX-8
RENESIS_an engine replete with innovative technologies such as side intake/side exhaust porting_is a 654 cc x two rotor unit. Because it has a new side-intake and side exhaust layout, the engine delivers 250 horsepower at 8,500 rpm and 162 lb-ft of torque at 7,500 rpm without the weight and complexity of a turbo- or supercharger, while achieving improved fuel efficiency and cleaner emissions.
Happy reading!
