vanwyk4257 & Superman have given you good advice. Do some searches to verify what they said. I've posed before on tub wts.; wt. of the galvanizing treatment & etc.

The nice things about DME is that you can chip it be much better than CIS at any rpm range; it outperforms CIS at higher rpms already; and it can be made to work with higher EtOH levels and CIS will be in trouble there.

That said, if you get an SC, you can always drive it with the CIS motor and then covert to an aftermarket EFI later.

Be SURE that will be allowed by your state DEQ. If in doubt, backdate a Carrera not an SC.
