All great information above - good stuff guys.

The only thing I have to add is that Porsche never added Motronic EFI into their turbo cars until the 993TT I believe. All previous Turbo's were CIS injected.

This is interesting as other car manufcaturers were running more sophisticated EFI systems in their turbo cars o the same era. Anyone know why Porsche delayed adding EFI until mid the 90's?

Even RUF went with a Motronic EFI in their mid 80's CTR conversions! The 962's were even Motronic based motors (Motronic V1.7 I believe). WHY didn't Porsche do it?
