what are the benefits of the Cosworth engine, apart from more power?
I agree reputation and proven success with Ford. Most successful UK Formula 1 engine manufacturer and second only to Ferrari worldwide.
Also Sierra and Focus prove they can make fast road cars.
I had a Cosworth engine in a 1650cc Series 5 4/4. It was well made and all the weak points were uprated. It had power right up the rev range.
If I was offering a tuned engine on a production car, like Caterham, I would go to Cosworth.
Standard Ford crate around £2500 Cosworth 205bhp £6800 (source Burtonpower).
I would have been tempted to tick that box if it was included on the options list and done without door handles.
