you have to figure out where you can hang the turbo to get the piping to and fro and then start by making at least a temp mount to put it there. Cardboard and pvc can be your friend in the early stages. The next one I build I'll have a vertical band saw (even just a cheap harbor freight one) and a bench sander to clean up the angles. Sawsall with hose clamps as cutting guides was still pretty difficult to do well for me.
