Different Types of Engine - Pro and Cons
Posted: Tue Nov 06, 2007 6:24 pm
Thought it would be interesting to hear peoples opinions on different engines eg Pros, Cons, Cost for a Rebuild etc.
I'll start with
Rotary Engine - found in RX7 (FB, FC and FD), RX8, Cosmo etc

Pros
Easily tunable through porting of the engine, different turbo variations etc
Extremely smooth right up to the redline.
Lack of internal parts so rebuild is easy to do and can be cheap.
Lightweight for a 2.6 piston equivalent.
Cheap Tax - classed as a 1.3.
Cons
Very sensitive to both fueling and induction.
Rotor tips can wear out anything from up to 80k miles (common for it to last up to 60k).
Not easy to create a fancy enginebay due to engine being buried eg no Cam cover
Very low torque
Price of a Rebuild
