I went Turbo because I had the Money to do it and I had the time for the car to be down during the build up while I was on deployment. I decided Turbo over SC as I had a KB on my Lightning and saw the clear advantages of going Turbo after building my Lightning to run 10.63 with no nitrous. Turbo bottom line will put down more HP but will cost more. Reason why not a lot of guys have them or do not have them really set up for them. I have a lot more then 10K in my setup but I started with a very close to stock car and had just about everything done to mine. AODE, T-76 Hellon kit, Fuel system, Solid rearend, Drag wheels............. the list is VERY long.
