I think I would try to keep it all Nisson or Honda, rear end ratios might be a bit easier to find, a lot of that stuff is all from one place, Toyota might be a nice place to search, and aftermarket hopup stuff is more available, better grab ya a spare midget chassis while they are cheap, plus a good 5 or6 speed trans before things warm up, been a looooong while since I had to wear a heavy coat in a "yard"! Still think it's worth a look, it doesn't look like racing is going to get any cheaper, and there may be plenty of races to go to, but if they don't pay well, sure won't be many "road trips" like we used to pull, but it was fun while it lasted, course I pulled all over the 48 racing go-karts, and never picked up a dime that wasn't already mine, had a lot of fun, met a lot of nice people, went a lot of places people wouldn't normally go, used up a lot of that nasty fossil fuel, even carried extra cause gas pumps were locked on Sundays, anyone remember what year that "ruse" was launched on us? Oh well, it wasn't all a dream, it's been a fun ride! Bob
