Hey Eric,
we need to hook up sometime... I live just south of Dallas...
I noticed that you just started autocrossing.... Novice C-Stock, right? I
used to do some serious autocross racing and road racing.... I'm putting
together a nice little Porsche 914 so I can start autocrossing again....
I'd be glad to help you out in any way that I can...
That Swift GT motor revs pretty high, and the turbos should work well with
it...
Later,
Tom "Slick"

well!!!"
