GS-R on the left, ITR on the right. ITR also has the limited slip, 15 lb flywheel (as opposed to 18 lb on GS-R) and different clutch.

1st 3.230 3.230
2nd 1.900 2.105
3rd 1.360 1.458
4th 1.034 1.107
5th 0.787 0.848
Final Drive 4.400 4.400
Reverse 3.000 3.000

Besides that...they should be the same.

All I can say is that when I put the LS fifth gear in, I used the stock 5th gear syncro

I think other than the gears and lsd, they're the same. GSR's also use the dual cone syncros i believe. There is a tranny guide on http://www.hondaswap.com <--excellent information.

What is the benefit of the LS 5th gear? Is it giving you more top end or speed?
This is the first I have heard of this but I am interested!

Thanks

At high cruising speeds on the freeway, it doesn't sound like you're in a bee hive.

I have a GSR integra. theres not a big difference between a GSR 5th and an LS 5th. But when I went with the ITR tranny, Id be in VTEC all day since it comes on at 4400 RPM in a GSR. So I just decided to get the biggest 5th gear they make.

I don't have it. I thought about it years ago.

I doubt you're the first one to do it.

Its possible, but wouldn't you rather get an itr tranny and swap in the gsr 5th?

Unbeatable MPG y0!

Will you be at the double header this weekend at Nassau? Or you need to break in the tranny? Does it come with LSD?
