That isn't nearly as cool as GixxerKart. Plus, ever since they put those plans on the internet for using an old turbo to make a jet engine, everyone is doing that. GSX-RKart is the way to be for sure...I'll try to find a clip.
That is something I have been wanting to try. I saw a video where they somehow drove the rear wheels from the turbo so that it was not using the thrust but some kind of drive system. Burnouts were very cool and was much faster. Looked like it could snap your neck.
I had the gixxer-cart video.. that thing rocks.. I have a race go-kart back in AUstralia that we were mounting an YZ80 motor to it.. never finished it... tryign to get my dad to ship it over to me... so I cna finish it in my shop...
