ok, i have a fully built and boosted GSR in an EG coupe. it has gear dependant boost, and will not hit full boost until 4th gear. The car is a full street car, and will be a weekend warrior/fun car for the weekdays, but not a daily driver. i am trying to decide on what transmission to use. the car should make around 500hp, being on 21lbs. i have a GSR tranny right now, which i was thinking putting a type r LSD, and a 4.9 final drive in. on the other hand, i could just get a JDM ITR tranny. im not too sure which would be better, does anyone have any suggestions?
