Im in the market for a final drive for my gsr w/ i/e. Im mainly in the looks at the JDM ITR one cuz it's in my price range. How many of you are running this final drive on your tranny and what kind of gains did you feel?

Have any of you raced a usdm type r on the track or anything and noticed your much closer than w/o? ALso how is highway driving w/ this?

If you guys know of any good prices or sites to get them at, or anyone selling some for CHEAP. let me know here. thanks

 

k..

 

id like to know too...but id rather go with an ATS 4.9

 

ATS is not practical at all if you daily drive. If you're all race it's okay tho.

...sells JDM ITR final drives for decent prices.

 

80mph = 3900 with stock GSR tranny
80mph = 4400 with stock GSR tranny + 4.78 final drive

Inlinefour has em for like $480

 

you are looking at something like 58lbs of absolute torque gain in 3rd(too lazy to look it up).
Anything higher than the 4.785 will put you at a crazy rpm for highway speeds.

 

I have the JDM FD installed along with the LSD on my GSR tranny. It's one of the best mods I've ever done to my car.

Yeah, it revs high when cruising on the freeway, but I still get about 28 mpg with it.

It just makes the car so much more fun to drive.

 

yeah i have intake/header/exhaust. Do you think this mod will be my best mod to date and the best mod i'll probably even feel?

And i do want a JDM one, nothing more, 4400 at 80mph is high enough for me. haha

 

tranny mods are one of the best mods you can buy.
whether it be jdm itr final drive + lsd/fly wheel/performance cluth.....

remember whatever power the engine makes; it has to be converted through the tranny.

**putting in the jdm itr final drive will put the gsr gearing slightly above the usdm itr gearing.

ats 4.9+quaife+spec clutch is whats goin in mine

 

Have you thought about getting a JDM ITR tranny?

You get the 4.7 final drive, closer gear ratios on 2,3,4,5 and an LSD (the best part if you ask me).

Cheers,
Sean
