a friend of mine is going to get a built gsr motor put in his hatch in pretty soon and the guy that is going to do everything told him if there isn't a gsr tranny available at the time, he's going to throw in an ls tranny. what do you guys think of that? is that good, having an ls tranny on a built gsr motor?

 

i'm gonna go with not good, why build a motor and put the wrong tranny on it, get an itr or b16, better gear ratio

 

The LS gearing is WAAAAAAAAAYYY too long. I wouldn't use an LS tranny for NA or FI. Shorter gearing for me please.

 

It's not really that long, but you will benefit from gas mileage and highway driving. But either way, he should get a B16/Type R tranny.

 

why does everyone always reccomend the B16 tranny for built motors?
GSR may have longer gears, but the differential is built for power.
Si/LS trannys have TINY *** diff gears that will spin and break. Saw it happen
more than once. If you have ever seen the difference between the diffs...
you would put a JDM final gear in a GSR before dropping in a B16 tranny...

ITR is always nice though...trust me on this. Agressive launching on a B16
tranny will spell its demise eventually. You can only buy the whole diff from
honda and its $650 bucks.
