I'm generally new to Nitro RC all in all, and recently bought a MG16 Monster Truck off of eBay.

When I received it, the thing had been beaten to hell, needed to be disassembled to nothing, cleaned and re assembled.

Upon first driving it, I realized the exhaust wouldn't stay together with the way it was, so I used Locktite, and still it vibrated apart.
after countless amounts of frustrating hours, I finally just decided to buy a Traxxas exhaust from their 2.5 that I ghetto rigged to fit the back of the car. It works much better now, no problems and even sounds much better.

I've installed heat shielding to the fuel lines, and even added a fuel filter (just for extra safety!)

Now I'm stuck.

I enjoy doing big mods, and things other people haven't really done. and it seems with this car there really isn't much else I can do.

So, My question is;
What motors fit?
What other things fit from the 1/10 models?
What else can I do to improve performance, or even cheap cool things?

Thank you for viewing my thread.

Two more questions I cannot seem to find any information on is;
What size Hexes are the wheel hubs,
and
What nitro fuel %/oil % is best for this vehicles stock motor, in the case that I cannot swap it with an OS motor, or even the GST 7.7
