But going back to this subject I wouldn't mind seeing an RCF engine in an ISF for one reason and one reason only.....having the RR Racing Supercharger intake pipe oriented like the RCFs have rather than how the current setup on the ISF does.....I'm worried when I pull the trigger on the RR SC it'll suck up some nice water if I go over a puddle in the UK

Rafi, is there no way to redesign the current ISF Supercharger intake pipe to be oriented up like the RCF?

(1) RCF runs 800psi higher direct injection fuel pressure, uses different DI pumps vs ISF.
(2) RCF uses different port injectors
(3) ISF transmission ECU would have to be reprogrammed in order to lock the TC up to 7200.
(4) You cannot swap the RCF and ISF ECU's... they are way different, completely different generations and chips which must communicate with the rest of the CAN-bus system or nothing will work.

So yeah... it would be easier to rebuild the ISF engine for higher compression, ported heads, and cam modification than to swap an RCF engine into an ISF.
