    I understand the rule on limiting cars to 8 engines a year without a penalty (and to a lesser extent gearbox quantity limits). What I’d like to know is what is allowed in terms of changing out parts.

    Engines have hundreds of parts. At what point is an engine so changed until it is considered a new engine? Obviously the engine block is the most basic component, but can you change out cylinder heads? Cam shafts? Drive shafts? Valves? Springs? etc.

    Just wondering if anyone has info on that.

    Thanks!

    I’m pretty sure I remember hearing that any *mechanical* repair/modification counts as an “engine change”. So I think that things like cylinder head, valves, etc. are not allowed to be changed, but wiring IS (because it’s not “mechanical”).

    It’d be nice if someone could confirm/correct as I’m not 100% sure- I can’t even remember where I heard/read it.
