JDM GSR motor wit I/H/E/CAT/FLYWHEEL/CLUTCH/FPR/VAFC2. Everyone seems to have their own opinion on to 2.5 on N/As, i know some people wit N/As running 2.5s that say its worth it. Im going to run the car wit the exhuast leak next week and see what how it performs, if the MPH is higher than the normal 93-94 then I will know that the 60mm exhuast has been holding me back and I will upgrade.
