The 20B is the big power house in the rotory world (excluding the 4rotor 787b). The sound it makes is better than any v12 engine out there (the 20b is compared to a v12 engine). The motor with the factory twins can make close to 500hp but if you put a single turbo on it then the thing is untouchable. The only problem is that there isn't too much support for an engine up here. Here is some info from www.pettitracing.com under the banzi banner:
After having the opportunity to drive some of the world's fastest cars, from Lamborghinis to Ferraris, few cars remain that can elicit emotions that amount to fear. But when you begin with a turbocharged supercar bred for racing and double its power output, you have the foundation for such an animal.
Pettit Racing in Fort Lauderdale, FL, has created the Banzai RX-7. Dispatching the quarter mile in a scant 11.4 seconds at over 126 mph, a driver is just at the first half of the Banzai's performance envelope: top speed is estimated at 240 mph. The brainchild behind the flawless conversion is veteran racer, Cameron Worth. Worth has a long record of racing rotary cars that dates back to the seventies, so it seems fitting that he transfer that knowledge to create a street-legal "Road Warrior" - as he calls it - capable of blowing the doors off supercars costing nearly twice as much. He does it with a turbocharged, 3-rotor conversion.
Under the hood, it seems less cluttered than its two-rotor counterpart. Fitting nicely, everything looks as if it is the way the engineers in Japan had originally intended it. Perhaps what is so impressive about the car is its civility. It can be idled around town, yet it can be rocketed down the on-ramp with a ferocity that words simply cannot explain; it must be felt to be believed.
Everything about the conversion is state-of-the-art. The craftsmanship, down to the self-locking nuts and liberally appointed hiem-joints, is testimony to its racing heritage. Its character is reminiscent of the finely tuned Alpinas, Hartages, and other high-performance gray-market cars that made it in the window of opportunity left open by sleeping legislators. But the spec box only tells half the story.
The other half comes from the Banzai experience that Worth is gladly willing to share with serious buyers who fly into Fort Lauderdale International Airport. For those power junkies who never seem to be able to get enough power, brakes, or handling, Pettit Racing's ride back to the shop will be burned into memory forever. Try it, it's a ride well worth the plane ticket.
3 Rotors
2 Sequential Turbochargers
2.0 Liters
550 HP @ 7500 RPM
460 Lb-Ft @ 5500 RPM to
propel 2735 Pounds of Canyon-Carving, Freeway-Dissecting, Corner-Chomping, Pop-Your-Eyeballs-Out-Braking, Two-Seat-Heaven RX-7
The Banzai Edition RX-7 utilizes a 20B three rotor twin turbocharged engine which produces 550 Hp, propelling the Banzai to light speed in a flash. The Banzai is fitted with a huge custom built front mount intercooler, hi flow radiator, and retro fit air conditioning condenser to handle the extra cooling needs. A special computer-designed subframe fits the 20B power plant perfectly into the RX-7 engine bay and allows easy access to all components for service. A custom Digital Management System provides unsurpassed drive ability and unbelievable performance without all of the spaghetti wiring of the factory system. A TKT Stainless Steel Exhaust System gives it the perfect note. Special Trak-Pro suspension and brake systems handle the extra performance with ease. Power is transferred to the ground via Bridgestone Potenza S-02 225/40ZR18 front and 285/35ZR18 rear tires mounted on beautiful 18" x 8.5" front and 18" x 10" rear Forgeline LS web design wheels.
Pettit Racing's products have established a firm foothold in the RX-7 performance and accessory market for the average RX-7 owner as well as the true enthusiast. In order to maintain our position as an industry leader, Pettit Racing actively competes in professional road and drag racing. Since 1980, Pettit Racing has won 5 road racing championships, set several track records, and competed in countless drag races. Our quickest quarter mile has been 10.855 seconds.

| I don't get it - what does this RX7 provide that a car such as a Z06 can't when it's upgraded? |
|
|
| crazyrx7 |
It will cost half the price of a z06 stock. I don't want to start a flame war but a single turbo 3 rotor would own any modified z06.
Those horsepower numbers are for the stock turbos on the 3 rotor. Enough said.

You get the RX7 + the complete "Banzai" package for 30K USD?
If so, that's a pretty sweet deal.... |

This thread is about the 20B rotary engine.
Please limit your discussions to it.
You can start up a 20B vs Z06 thread if you wish but that topic is for another thread, not this one. |

I love mine. 370HP at the rear wheels.. who can complain.
But the best part is when you realize that at ~5psi of boost and reving to a conservative 7k rpm, the 20B is barely waking up. Throw in more boost or more rpm (or both!) and you'd better make damn sure you're ready to lift when the rubbers start peeling through the gears.
Reliable? Hell yes. Anyone who says no just doesn't know what they're doing with them. You can't (I repeat, CANNOT) tune a rotary like you would a piston motor. But don't believe me how reliable they are, ask the people who's LIVES are dependant on the reliability of the motor (airplanes), like these guys:
http://www.vansairforce.com/communi...p=9444#post9444
The 20B is a popular aircraft motor, with companies building them to run 6000RPM all day long while putting out 450HP with 30,000 hours between rebuilds.
God's gift to engines? Maybe, if you treat it right. With like 3 moving parts there isn't a whole lot to go wrong :) |

omfg :blink:
so much power
:D :D
:D :D :D
I want 1
actually maybe not. |

I can't tell if you're serious or being sarcastic but ok. The 3 rotor seems to be able to make up to 1200HP with major mods (400 per rotor), maybe 900HP staying more reasonable (300 per rotor). 450HP is possible day after day (150 per rotor). In high-horse applications they are generally more reliable than a piston motor as they don't need to be rebuilt (they don't suffer from bearing and sidewall stresses) as often. If 1200 wasn't enough for you (?) you could always put together a 4 rotor.
This is a really good page to check out:

4... the 20B has 4 moving parts. ( 3 rotors and the eccentric shaft ). On another note, yeah it is a kick-ass engine! |

holy old thread batman.
and if you have a modded 3 rotor and you are worried about fuel economy you are in the wrong game.
hell if you are on this forum and worried about fuel economy you are in the wrong game. |

RX-7 Specialties in Calgary will build you a 20B...or maintain your 20B.
http://www.rotaryengine.com/engines.htm
Side note on the 20B...in that it can also be referred to as a 13G, which was the nomenclature used for it in naturally aspirated conditions...the 20B nomenclature implies a turbo-charged engine.
Plenty of three-rotor FCs, FDs, and a few RX-8s on the road, apart from the oem 3-rotor Cosmos of the Japanese (and Australian gray-market). |
|
|
| McFly |
there is many differences between the construction and internals of a 20b vs 13g.
and rx7 specialties are a bunch of over priced hacks. |
