I have a b16 tranny and and ITR LSD. I know I need a GSR ring gear ro make it fit, but I am simultaneously installing an LS tranny's 4th and 5th gear along with the LSD. now my two questions...

1) Do I still need specifially the GSR ring gear?

2) Does changing the ring gear affect the overall ratio of the tranny?.. meaning will 1st- 3rd gear still pull like a normal b16 transmission, or will the new ring gear multiply the ratios. and make it pull similar to a GSR tranny?

thanks in advance

im not sure if i understand u right.from what i understand u hv b16 tranny n itr lsd.im sure u can use ur b16 FD back.is your tranny a hydro type?

 

gsr fd is the same as the b16 hydro fd(as well as the JDM ys1 cable tranny,this is what mine is).if i were u,get the ctr FD instead.

 

I have a 00 tranny and I know for sure my ITR lsd wont fit. thats not the question. I am adding an LS 4th and 5th gear and I wanna know if thier ratios will be the same or get multiplied because of the GSR. final drive. or maybe Im a bit confused. is the 5th gear the same as the final drive ring gear?

 

1) Yes, The B16 and ITR diff are physically different sizes so you still need a USDM ITR or GSR ring gear.

2) Yes, The final drive size does change the overall ratios, but not in your case since you will still be using a 4.4 ring gear.

I understand what you said. because the final drive from the GSR is 4.4 (just like my b16) but remember I want to add an LS 4th and 5th for its long ratio. but I am thinking that if I do that and retain a 4.4 final drive. it will make my 1st to 3rd even closer and the LS gears as close as the original b16's 4th and 5th. the LS gear ratios looks like this..

4th: 0.966
5th: 0.714

if you multiply 4th gear by 4.4 you get 4.2504
if you multiply 5th gear by 4.4 you get 3.1416

those ratios look MUCH closer than before.

 

Where can I get a GSR ring gear?

 

1) You need an ITR or GSR 4.40 ring gear.

2) By swapping the ring gear, you won't be able to change anything on the FD. The ring gear and countershaft dictate your FD. The countershaft is a lot of fun since it's bolted into once piece and each ratio is pressed onto the shaft.
