pordon me blinx for forgetting to put the question, can i just fit in the s4c EK4 non lsd with this oem 4.785 fd without installing the lsd.
cheers!!
my 1.6vti (EK4) is non lsd s4c tranny ( and planning to fit the ITR 4.785 fd in it. some says, i do need at least an oem lsd to fit the fd in, and some says, it should be fine to just plug n play.all the items, 1st gear, collar, counter shaft, ring gear and 2 bearings are all complete.
hope any other fellow friends who encounter the same question before could leave some comments.
cheers!!
Yes, you would need to change 4th gear, 5th gear and the final drive.
Please don't change the 4-5 gears to 98spec.... you'll lose the manic pull esp. if your car is not a B18.

The EK9 4th/5th gears are shorter than the ITR '98 box (they are about the same in terms of closeness though). The 1st/2nd/3rd are the same. The only advantage the ITR '98 box has over the EK9 box is in 1st/2nd/3rd due to the 4.785 FD.
Yes, I would recommend keeping your current 4th/5th and changing the final drive.
Alternatively, you could install a close ratio gear set instead
