Is the SR20 a good engine?
While the SR20DET is a great motor, it’s not without its weak points that have been frustrating tuners since its introduction well over two decades ago. The SR20 is the ideal entry point into high-performance aviation. Equipped with a robust Lycoming IO-390-C3B6 engine, it delivers 215 horsepower, making it an excellent choice for pilots just stepping into the world of high-performance aircraft.When comparing the two engines tuning potential the additional power that the SR20DET can handle would give it the advantage, while both engines can be built to achieve high power outputs the larger displacement of the SR20 should allow it to get on power sooner then the CA18. The SR20DET wins on tuning potential.
