I have an LS tranny which has longer gears, which i was told is good for a NOS or turbo setup. however the problem is that i dont have either one of these setups yet, therefore i dont wrap the gears like i used to. should i buy a GSR tranny until i get a nos or turbo setup or keep the LS and how much power exactly am i losing?

2000 civic si
B18C JDM swap

 

personally id get a jdm itr 4.7 fd tranny. but I think itd be better if you see what it's like with your ls with fi setup first.
