If you're willing up upgrade to the Supertech valvesprings and retainers (probably $700+ retail, plus install) and raise the rev limit 1000RPM+ over stock and have to spin it that high to get it to do anything, then you run the 2000s.


When I had the 2000s in, I made nothing (as in less than stock) until almost 5000RPM and had to spin the car to 7000RPM every day to get it to go anywhere. With the 1000s in, I make stock below 4000RPM and significantly above stock from 4000RPM to 7000RPM.
Thanks. Don't get me wrong. I'm sticking with the 1000s I have. I'm very happy with them since I don't feel any need to win some horsepower/dyno battle at 7,000RPM. Jerking my head back at 1,500RPM from all the torque is more my style
