Going to base this off of what someone would have built in the beginning of the nitro craze before conversion kits were available. Only sacrifice to original parts will be a used chassis. Trying to not modify any other parts that can't be returned to factory later down the road.
So far all I've done is notch the chassis and mirror a bunch of parts. I'll get some thicker scrap alum that will bolt to the left engine mounts and behind the baseplate. Will use a band style brake off of the clutchbell, and a muffler that will exit out the rear through the shock tower.
Here is a few pictures to show where I'm going with this. Still a ways away but you'll get the idea.



Running out of things to do that don't require tons of money or elusive parts that I can't get ahold of so I'm starting a new project I should be able to do with what I already have minus a few home made pieces.
