Im boosting a B18C with a gsr head. Built bottom end, built head, and im running a gt30r turbo. I am now down to buying a transmission. I just dont know weather to get a gsr trans or an ls trans. A lot of people say ls is the best way to go for boosting, but then again they say it has too long of gears. I just wanted to post this out there and get feedback on what is best. Thanks

 

Ls longer gear
