I know of the following: Euros have more aggressive cams higher compression ratio Differernt exhaust manifolds What else? During a 30k would it be possible to swap to the euro spec compression and cams? (since much will be out and apart anyway?) Just wondering what this entails for reference.
You'd need the Euro pistons, cams, ECU's and full exhaust and some bits of fuel injection system. Then the brackets would need work for mounting to the "wrong" chassis. The pistons couldn't be done at a service. Would be a better cost/result ratio to go for a turbo conversion to the USA car. Just removing the cat and fitting a sports air filter and silencer will make a reasonable bang for buck on a USA car. Use high octane fuel too.
Did that. Cat-bypass pipe and tubi I was thinking of getting the more aggressive camset and just swapping it in. when I get my next major done.... Guess that is not an option.
I thought that if you don't have the compression ratio to take advantage of it, you don't get any advantage from the extra octane. This was discussed in some depth on the old FChat by some chemical engineers (of which I am not one!).
