stack parts and do it right / do it once. I m telling you this from personal experience, the route you are going is extremely inefficient and wasteful. To spend $1200 now on turbo's then another $3500 does not make logical sense. Once again, make a plan and stick to, this car will bury you otherwise, regardless of your passion.
You have a vast resource of knowledge available to you if you chose to take advantage of it...........
