I feel like Toyota builds are the coolest with small motors and crazy gears.  I think a 4BT Scout Rockwell Buggy is where it's at if you want to do something with  that  motor. 

Too many of those..

I really wanna see a 4BT in a Toyota based buggy(I believe I ran into 1 on Pirate a couple years back..but havent searched for it since then)..but non tuned up..just a stock 4BT with a stack out da back.
Long as you don't Lead Foot Louie iteverywhere you shouldn't break too much stuff.
