We are breaking the CA boxes mainly 3rd gear like there going out of fashion.The quick drift boys are now using the rb box behind SR adaptor(differant to CA pattern)and not having issues.A ppg gearset is 8k,replacement broken genuine parts only ex japan is around 1.5k.The CA boxes are all getting old and long in the tooth and fragile,reasonable HP on slicks is no friend of any nissan box ever made in addition we plan on upping the ante to 300rwhp later in the year,we will juat have to put up with a bit more weight
