Well just to let you all know the gsr cable and b16 cable trannies are basically identical in gearing. My buddy has a gsr tranny in his DA and I have a b16 tranny in my EF and at 70mph im at like 4grand and he is at like 3800 but My geuss is that our tachs could be off a little too which would probably put us at identical rpms at the same given speed.
