I agree. It is difficult to beat CIS for simplicity.  While I no longer have
the WX, my plan is to complete the MC-2 in my car with the CIS-based MAC-12
it came with ... the MC-2 can put out some pretty good numbers and retains
the character I like from the original powerplant.  

I suspect many of the folks who love the 20V/EFI are looking to tweak their
powerplants for maximum power ... and there's little question that a modern
EFI system can optimize the combustion process for each cylinder.  The thing
is that I know folks who have done the 20V turbo swap into their urq and
have spent a lot of time troubleshooting issues ... 

I think it is a bit of a crapshoot ... either version can be easy or a PITA
... perhaps it is the luck of the draw ...

I like CIS, and its actually fairly adaptable. I thought it would be a pain
to re-setup on my engine swap, but it actually worked like a charm On Jul
