I am not trying to be lazy.
I tried to search, but I don't why whatever I typed end up no matching result ..
Anyway,

The story is:
I try to put a LSD, 4.7 or 5.1 Final Drive and a TSX or Civic 6th gear into my 03 RSX Type S's 6spd tranny. I saw some post mentioned that mainshaft has to be change as TSX or Civic SI. But I also heard of people saying that I don't need it...
Can someone give me a clear answer?

I just want to make sure those are what I need:
Civic Si Final Drive: 41233-PRT-000
Ball Bearing: 91005-PRS-003
Countershaft: 23221-RAS-003
6th Gear on Counter shaft: 23491-RAS-000
6th Gear on Main shaft: 23590-RAS-A00

Is there anything missing?
TSX or Civic SI's Mainshaft really NEEDED?

Thank you very much guys!

The 06+ Civic SI has a 4.764 final drive. It doesnt matter if it comes from the Type-R, TSX, 05-06 RSX, 02-05 Civic Si or 06+ SI, they're all the same ring and pinion.

Cheers.

Ok, let me get this clear:

IF I want to replace 4.7 Final Drive,LSD & TSX' 6th gears,
I'll can use final drive, counter shaft & ball bearing from 07-08 Civic Si & I wlll need TSX' 6th gears w/ TSX mainshaft plus bearings, shims and synchros?

IF I just want 4.7 Final Drive & Quife LSD, I can just use Civic Si's?

Thank you .
