Starting turbo!
Too much power? Is that possible? With a turbo its always just a twist of the boost controller or a different spring in the wastegate away.
Do it. I had/am having the same issues with my Scamp, and I have don't even have to worry about half the stuff you do. This stuff adds up quick. I had to change motor combinations a couple of times. I finally decided it doesn't matter how long it takes me or how much money I have to spend to get what I want. It's going to be done. I won't be happy with it unless it is exactly what I want. I imagine you are the same way.
