SCCA GT2 conversion

[John Goddard <jgoddard@xxxxxxxxxxxx>]

I haven't been keeping close track of the situation, but the last I heard,
the SCCA competition board was planning to begin allowing fuel injection in
1999 in the GT classes.  You should probably call Denver to see what the
status is.  You could either stay with the stock FI setup or choose an
integrated aftermarket setup.

If you go to carbs, there are aftermarket ignition "boxes" such as
Electromotive, MSD, etc.  Most of these have rev limiters, variable timing,
etc.  You'll need to do some research on what's out there right now.
