In a weeks time, i will be installing a 99 USDM ITR swap into my 92 EG hatch. At the shop where i am getting the work done, they happen to have a JDM ITR tranny with the 4.785 final. Will there be a huge difference in the 2 trannies? Is it worth the extra cash to have them install the JDM one?

 

There is no such beast as a 99 USDM ITR...we only had them 97-98 and 00-01...

the final drive is for quicker acceleration, goes through the gears quicker...

 

Well i am not sure about the States, but here in Canada, there is a 99 for sure.

 

that is correct...

 

What are they wanting for the 98 Spec tranny?

 

As long as its not too much more and the tranny is in just as goo dhsape then I would go for it, As long as its a 98 spec tranny.

 

nah, keep your $$$ and the stock tranny. when you get up money and want to upgrade, swap in a clutch type lsd, 4.93 final, flywheel etc.....

 

Huge difference...much quicker acceleration/proceeds through gears faster!!! (ie: what the other Jason said)

DV- who hopes to have a JDM or Spoon tranny in the future

Hey EG-Six, do you ever go to the weekend runs in ottawa?

 

Hey EG-Six
Which shop do you go to? I'm in Ottawa too. Maybe we could meet up sometime.

 

It's a nice change from the normal 4.40 final drive.
You'll notice the difference right off the bat - it's not some minute little upgrade.
Acceleration is greatly improved along with about 15% of more torque too.

If you do get this 4.7 tranny, I suggest you get a lightened flywheel also - man..lightened flywheels should come standard on every Honda!

 

hey katman, do you think getting an itr tranny for my ls is good or spend the money elsewhere?

 

Yep...Im sure there is quite a bit of differance.

Going from stock tires to 205/40-16s changed the final drive from 4.40 to 4.59 and I can tell a differance in that..so Im sure a differance from 4.40 to 4.78 will be quite noticable.

 

...or get the 4.785 FD and some 205/40-16s and you'll end up wit ha Final Drive of 4.975!

That will be a HUGE improvment

 

Does the wheel size affect the final drive ratio? A smaller wheel increase the findal drive ratio??

 

yah it's good..cuz not only will it help acceleration..but if you ever upgrade to lets say, the dreaded LS/vtec setup or even a B16A....all you need is the long block...not the whole engine+trans.

 

Yes it does.

Final Drives are "rated' with a stock size diameter. In alot of cases the stock diasize is 23.44" (195/55/15)

If you were to use 205/40-16s..the diameter changes to 22.46"...a whole inch smaller...which in turn changes the final drive from 4.40 to 4.59.

 

it sure does..
the JDM 98 ITR has a 16 wheel w/the 4.7 fd for a reason

 

Although I didn't drive the car, I rode in yeahls' ITR equipped with JDM final drive at the ITR Expo and even from the passenger's seat I could tell that the car pulled alot harder when the driver got on the throttle. I was impressed when exiting turns how fast the car was and there is a noticeable difference!

 

yeah ive noticed that too LL..but doesn he also have like a GSR 3rd 4th gear or soemthing?

 

His car is stock except for the JDM FD and springs. Yeahls got skills!

 

98 JDM DC-2.R has ITR/B16 1-3 ratios and GSR/Si-G 4+5th ratios.

Whut about for the 2000-01 models?

 

dont forget the GReddy, but i think he DOES have one of the GSR gears...well i think thats what he said.

 

I didnt know that.....sounds like yeahls tho!
