Hey everyone,

I read on some old threads that if the Euro fuel pump relay is used from a Euro 16V in the US 16V, it will give our car the Euro rev limit of 7000rpm. Does anyone know the part number or where I can find one? Also, will there be any difference in performance or will the only change be the new rev limit. Do the valve springs need to be changed then? If so, is Bekkers 8000rpm valve springs the only solution?

Edit: I also forgot to ask if a fuel pump relay from a 300E could be used in this application?

Thanks for your help,
Giancarlo
