I just bought a car and I’m already thinking of what’s going to replace it. After watching Jeremy Clarkson’s gushing review of the Mazda RX-8 I have started thinking that I really should own one at some point. Clarkson says “it’s not as simple as just replacing the piston rings in a regular engine” but... isn’t it? I mean, both require that you remove the engine (usually), tear it down a fair bit, and if I’m replacing rings you better bet I’m going to hone that bastard and clean up the piston and heads while I have them off. So how hard is it really to repair a low-compression Wankel engine?
