I need to decide which tranny to pair with my b18c itr motor. should i get the 96-97 itr or the 98+itr? what's the difference/benefit?
thanks

oh, by the way, i have both trannys so if parts are better in one and a combination of the two is best, let me know. i really appreciate it.

the '98+ tranny will allow you to accelerate quicker...with the gear ratios being shorter...it will also eat more gas for a regular daily driver...but this tranny would be better for the tracks.

the '96 tranny is more daily driver friendly...but it will not accelerate as quickly. I have seen a video where both a '96 and '98 ITR race and their quarter mile times were the same, eventhough the '98ITR accelerates quicker, the longer 4th gear in the '96 helped it to catch up.


So, its your choice.
 
ummmm then it would be the same as the 98

?????

if the ony difference is the final drive, and you switch it, then they arent different any more
 
well, i already had the 98+ tranny. now getting an engine tranny combo (cheaper that way) got the 96-96 jdm engine (500 cheaper then 98+) but the tranny i think might be in better shape. so i was thinking of putting the final drive gear from the 98 tranny i already have into the 96-97 i am getting. make sense? let me know if that sounds right.
 
wait a minute... :unsure:

i'm pretty sure (not 100%) that all usdm itr trannies are the same, with the 4.4 final. all 97 and below jdm itr trannies are the same as the usdm ones. the 98+ jdm itr tranny has the 4.785 final AND longer 4th and 5th gears. is that correct? i think it is.

EDIT:
it says so right here: https://hondaswap.com/forums/index.php?showtopic=29796

B18C5:
S80 (Helical LSD)

This transmission is one of the best B-series transmissions Honda has offered in its vehicles. Every gear has dual synchro's and the gearing is perfect for all motor applications. Plus, LSD is standard and will be stamped on the housing. Look to spend between 1200-1400 for these transmissions because of their quality, LSD, age and gear ratio's. Finally, if there is some question about whether or not you're S80 has 4.4 final drive or 4.7 final drive you can check the transmission housing. The code "4jhd" means 4.4 final drive was offered as original equipment, while "ne3" signifies 4.78 final drive.

The specs are below:

1st: 3.230
2nd: 2.105
3rd: 1.458
4th: 1.107
5th: 0.848
Reverse: 3.000
Final Drive: 4.400

B18C (JDM Type R):
S80 (Helical LSD)

JDM Type R transmissions are the best for all motor applications where acceleration is emphasized most. All 98 and up JDM Type R transmissions came with 4.785 final drive with the same 1st, 2nd, 3rd gears as the USDM Type R. To make highway driving more tolerable, the 4th and 5th gears are the same as GSR transmissions. Look to spend between 1400-1600 for these transmissions because of their final drive and rarity.

Here is a look at the specs:

1st: 3.230
2nd: 2.105
3rd: 1.458
4th: 1.034
5th: 0.787
Reverse: 3.000
Final Drive: 4.785
