I was reading an article in SCC the other day, and they had a huge section on the sr20 motor vs. the qr25. They are planning to put an sr20 crank in the qr25. This sent chills down my spine because of what they said, and i quote: " it will rev higher than the sr20 ever dreamed." **shivers**. i will let you guys think about that one for a while, but as for me im still a die hard sr20 fan and that will never change.
