after doing a search on ca 18 gear boxes i found a few people have had troubles changing over 5000rpm with the skyline shorty is there a way to improve the box to handle higher rpm changes or what are other alternatives to shorter boxes that arent rare
cheers

Stop the karate speed shifts and youll be okay, my man



PS, what if you're old and stupid?

i havent even got a box yet im just reserching at the moment but need the room in the ute.
i say that if your old and stupid ya still young at heart
