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.

Fair enough... You make a good point.

Long as you don't Lead Foot Louie iteverywhere you shouldn't break too much stuff.

Hahaha... yes! This is totally an interesting idea.

Are you thinking about running tons with it? It seems like just the weight of the motor could be an issue with toy housings?
