Hi Paul, Zorbi here...!
I have a inquiry about developments...!
There is a lot of modifications for rotary engines, about horse power,
torque, weight & reliability...!
My inquiry is about Mazda co & copyright...!
Can we interference at engine without license from Mazda co...?
If it is no problem why not see yet a full aluminum Renesis engine
13b & 20b from guys who love that what their doing, not for money, only
for the one & only reason, to support the positive side utility of
engine...!
The history teaches me that after a new rotary engine products from
Mazda then the rest engine products it is free for any after market
products...!

Regards...!
Zorbi from Greece...!
