i was wondering if it is possible for me to put a ls 5th gear in my gsr tranny when im driving on the highway my 5th gear is at 3500rpm at 70mph and since the ls is longer i was wondering if im going to see a big difference in rpm and gas only 5th gear thou

 

Been done before countless times.

 

cool anyone here can tell me the rpm at 70mph on a LS tranny? mine is at
2500 = 50
3000 = 60
3500 = 70
4000 = 80
its almost close 100 rpm give or take

anyone please post the rpm in an LS tranny on 5th gear please

 

You're probably lookin at around 3500 or so with the LS 5th. Just be glad you don't have a b16 tranny. I'd be happy with a GSR 5th. haha. Crusin at 4400 at 80mph.

 

70mph is 3k rpms with ls tranny
