Nope--Not into EFI and ECU(s); my cars are carburetted.

I will say that your motor cannot safely turn anything over 6500rpm on a consistent, continuous basis since it has hydraulic lifters (supposed to anyway)and an under-square bore/stroke relationship.

The 1.6 will turn more, but it is also limited by the lifters.

You are also not making power at those hi revs.
