if your wanting to make 1000 wheel its a good option, alot of blower for a stock engine imo, you need to decide what your goals are, you want a blower thats in your efficency range of where you going to be using it
Depending on what kind of power you're trying to make, the F1A might be a little big for you. The D1SC will still make big power and be perfect for a stock engine if that is what you have. Hit me up if you have any questions, I had an F1A on my personal car and I can get you a great deal on a Procharger kit. Lethalperformance.com
