Wankel rotary engines
We are one of the only tuning and performance garages in Europe that are specialized in rotary Wankel engines. At JT-performance we have years of experience with these kinds of engines. Due to our extensive knowledge we can quickly and rightly make a diagnose and therefor can help you very well with any kind of problem.
Most of this knowledge comes from one of our own track car’s the Rx7 FD3s equipped with a fully tuned 13B rotary engine and with allot of upgraded parts, which together combine the power output to over 500 horsepower. Because we also race this car, we can setup your engine for track use, and can get the most power out of it. Or a smooth pickup of revs.
Also we can do a full rebuild of your Wankel engine, where we replace all the worn parts and ensure you have a fresh engine for many miles of trouble free driving and fun. Also we can install upgrades and special parts to your wankel engine. If need be you can order an engine from us, which we will rebuild so you will have a completely fresh engine. We can install additional upgraded parts right away and we also can make custom parts for your engine and or specific wishes.
In-house we can make diagnose and test compression levels, we can do porting jobs and total and full rebuilds. Also setting up your wankel engine is no problem at all. We can do this in-house on our dynometer and if need be we can go onto the street with the mapping computer and ensure you get the best driving and performance to suit your wishes.
Please contact us for more information with regards to Wankel engine rebuilds, or upgrades.
How it works:
The wankel engine named after the designer Felix Wankel is a internal combustion engine that does not operate pistons and cilinders. But rather with a 3 sided rotor that rotates inside the combustion chamber. (See diagram) In the open space between the cylinder wall and the rotor the air fuel mix gets compressed and ignited. Due to the force the rotor turns. Inside the rotary engine the same combustion cycle occurs as with a piston engine. Intake, compression, combustion, and exhaust.
Since 1965 the Japanese brand Mazda started using the rotary engine for propulsion of wheeled vehicles. Throughout the years Mazda has developed the engine further and there now are various different engines available. 10A, 12A, 13A, 13B, 20B, 26B. The last one unfortunately has never been a production engine. Rather it has been used in various race cars like the 787 and 767 Mazda le mans style race cars.
Of all the various engines the 13B has remained to be the most famous. We also use the 13B engine setup in our own race car the RX7 FD3S. It has also been the base for over 30 years for all following rotary engines. The engine consists of 2 rotors with both 654cc together making 1300cc total. The total engine size is only 1.3 liters. This does however not mean it can not be a vicious engine for high power applications, with the right parts the engines can be tuned to over 500hp easily. And the rev limiter is often somewhere near the 8000rpm mark. Very interesting for racing applications!
