What are your favourite engines and why?
Mine are, in no particular order,
Ford Kent - Simple pushrod design, easy to work on, first engine I learned about tuning on
Ford Pinto - Heavy but uncomplicated, the basis for the famous Cosworth YB Turbo
Cosworth YB Turbo - Can produce 500 BHP on standard internals, show me another 2.0 engine that can do that without exploding
Suzuki GSX 1300 R - Lightweight, revs to 11K, can rev to 14K with some programming, the basis for all the best bike engined cars
Subaru EJ - Boxer design gives great stability with low centre of gravity, can produce silly horsepower and makes that noise only Subarus make
Peugeot XUD - Probably the most reliable diesel ever built, lots of torque, so good that PSA used it for almost 20 years in different forms
