Being taken out of context is such a wonderful thing.
My post that you quoted was a reply to this.........
"Evo's cost about $25000-$30000, if you bought an old dart for a few grand and dropped $25000 into a motor for it, you'll be running a hell of a lot faster than an evo!"
Please note.......... "dropped $25000 into a motor for it"
But onto your point...... Sure, with an unlimited budget you can build anything.
