Nope. I have heard that they are too wide but can't say for certain. I wonder if it could be done would the car still be legal for PCA events.
I just purchased a Mazda 20B (Twin Turbo 3 rotor engine) that makes 300 hp/300 lb-ft of torque stock. I am told that with the proper fueling, boost control and engine management the stock twin turbo's are good for 500 hp. I purchased the adapter plate for my 915 transmission from Kennedy Engineering (highly recommend them by the way.) The biggest challenge with the project I believe will be the cooling (radiator, intercooler, oil cooler) I plan on weighing the engine to see what it weighs. My car is a 914 with a widbody kit and currently weighs 1400 lbs. I figure if I can keep it under 2000 lbs and get 400 hp out of it I will have one smokin' ride. Here is the car:
and here is the engine that will be going into it:
If you want to know what one sounds like I have a video with a stock one installed in a Delorean and another highly modified one on a dyno.

There is also a great video of a 20B in a Toyota Corolla that has amazing acceleration. The link is here:
