I been racing it all motor and wanting to have more power without switchin out pistons and others...I got 12-1 compression sleeved 2.0L and wanting to boost or supercharger... But the question im asking is how much i can boost max on both and how much estimate power can i make?... My motor is fully built from head to bottom...

 

Zero boost. With 12:1 compression you are already close to detonation. You cannot build an engine to maximize all motor power and then strap a turbo on it.

 

hmm. how much boost you can run on a 12:1 compression

that's easy, none. if you do want to boost, you're going to have to lower your compression (maybe down to 10 at the least). so that means there is no gettin around swapping pistons, rods, etc. since you have taken time and money to build a N/A car, i say stick with the N/A setup. saves time and money. but if you do have the time and money to rebuild your motor, then i say go right ahead and boost.

whatever you decide, i wish you best of luck
