how much and how easy would it be to take out my orignal .15 cen engine and say put in a .15 novarossi or a .12, would a smaller engine rossi be any better than the standard 1 ??

Cossie,

Yes any .12 small block will fit with no problem. Our racers use nova rossi engine is sanctioned regional and national events. Another engine that we recommend is our 2.5 Turbo Big Block. Here is a link to some more info on it. Thanks for your question.
