That is an great resource. Now my question why is it so many people switch to a GSR motor?

I own a 98 GSR myself and like the car but it is only .4 seconds faster in 0-60 and around one second in the 1/4 mile vrs RS GS etc?

When I test drove a special edition before I bought my GSR I actually felt like it was a bit quikcer off the line.

Why all the swaps? Is it easier or more worth while to modify a GSR engine?
