hello , i currently drive a 94 ls with only 35k on the orig motor...but its an auto

im in the market for a new tranny and the necessary hardware for the swap......and i was wondering how much better is the itr tranny then the gsr

#1 would be the lsd...i guess is lsd really that great in a dd car? the gearing is a little shorter on the itr as well right .......other then that are there any other major differences?? how do both run at 80 mph in 5th gear also?

i would like the itr tranny if it fit my app......... eventually turbo.....maybe headwork looking for 240-260 whp stock bottom end

if not im sure the gsr tranny will do just fine

thanx in advance for reading

 

yup it's the lsd.

 

i did a auto to manual swap on my teg too, i got a jdm type r, and a stock b series head is good up to 500 plus hp so u should worry about the bottom end first.

 

98 and above jdm itr trans has 4.7:1 final drive as opposed to 4.4:1 thats in gsr and other itr trans. But if its strictly dd then it may not be for you, more shifting and worse gas mileage. The lsd may be good even on dd if you drive in f@#$% up weather like we do here in cleveland ohio.

 

Get a GS-R transmission, and add an LSD.

 

thanx for all the quick replies......4.7 vs 4.1 final drive could you explain exactly what final drive is ??

The ring gear on the differential is the final drive. The 98-01 JDM ITRs had a 4.785:1 final drive ratio. The USDM ITR and GSR has a 4.40:1 final drive ratio. To calculate wheel RPM vs. engine RPM do this:
(wheel RPM) = (engine RPM)/((gear ratio)*(final drive ratio))

 

so basicaly i can go a higher mph at a lower rpm

 

For a given speed and gear ratio, a higher FD ratio will yield a higher RPM.

A 4.4 would yield a higher MPH at a given RPM vs. a 4.7.

 

so for those long trips to the eastern shore the gsr tranny would be better

how about ecu......i've heard both you have to change it and you dont ( auto to man )

how about chipped ecu's ....would that be a good purchase..........ive heard even after an intake install you should tune a/f ratio ??? true?
