I just pick up a YS1 tranny the asshole i got it from told me it was out of a 93 gsr b17 that he was parting out so i met this asshole halfway because he was just over 2 1/2 hours away from me so i buy the tranny for 350.00 the next day i open the tranny to check it out its all good until i did a teeth count of the gears this is NOT a gsr tranny i go to call the guy and the number is now disconnected well i been fucked so instead looking for another tranny i was thinking of changing the final drive in this one from 4.266 to 4.92 here the before and after gear ratio's.
4.266 LS ---------------with 4.92 final drive with 8200 max rpm
1st gear 40.28 mph ----------34.92mph
2nd gear 68.47 --------------59.37
3rd gear 102.51 -------------88.89
4th gear 134.67------------- 116.77
5th gear 175.32 -------------152.02
by the way here the YS1 gsr gear ratio
4.4 final drive
1st gear 38.14 mph
2nd gear 59.92
3rd gear 86.45
4th gear 113.94
5th gear 144.15
so what do you guys think? should i do it?
this is where i got my numbers from if you want to take a look.
