What kind of oil is good to use on rotaries?
Depends on what year the car is, and what enigne you're talking about. Can't go wrong with 5w30, maybe 10w40 in older ones or in the winter
I know rotary engines use a lot of oil, but I was wondering what you guys use. How long does the engine last when you street port it?
Rebuild every 60k to 90k miles, regardless of apparent wear. Replace apex seals with good metal ones, not the crappy old ones.
Is there any special way of taking care of rotary engines?
Keep the oil topped off, check the apex seals if you start losing power of fuel economy, or if you start burning oil faster than usual. Make sure to use good gas (not dirty, at least 89 octane for N/A, keep ignition timing perfect, and other basic things to keep carbon deposits out of your drivetrain and sludge out of the oil. Change the oil regularly.
And, what do you guys do to get more horsepower out of these things?
Crank up the boost and keep air flowing in and out with as little restriction as possible.
