Ok so I am finally about to do something with the gearbox pieces I picked up a long time ago with the intention of installing onto my B18C turbo.
The plan is to fit hydro '98 Type R S80 internals into a YS1 casing to create a cable actuated R box to fit in a '91 Integra.
I have checked the tooth counts on the gears to confirm that they are from the right box-
Main. Counter. Ratio.
1st. 13. 42. 3.230
2nd. 19. 40. 2.105
3rd. 24. 35. 1.458
4th. 29. 30. 1.034
5th. 33. 26. 0.787
All ok there but the diff and final drive is a bit confusing. As you can see from the pics the final will need to be replaced but the tooth count on it is 14/68 giving a ratio of 4.857 instead of the OEM 4.785. I have counted multiple times so figure this must be an aftermarket final drive but does anyone know what it is?
The LSD diff also seems to sit into the YS1 casing comfortably but I haven't trimmed the internal ribbing yet, is there any way to confirm visibly or by other means what this diff is from? I am thinking it might actually be a optional LSD from a cable box, will this still fit and work ok with the other hydro internals?
Lastly, looking for opinions on what final drive to go for. The car will be heading to Mallala and Collingrove Hillclimb at least but I also like to go on a leisurely weekend drive in some of the open road 100kmh zones east of the Adelaide Hills. I have a S1 gearbox from an LS so could I fit the 0.742 5th gear in or will it not work with the other parts? The car has plenty of torque but the 4.7 sure is tempting instead of a 4.4 considering I hardly get out of 2nd in my standard b16 teg with a JDM J1 box at Collingrove.
And yes I will be going to Neat Gearboxesbut wanted to share on here for the benefit of others too.
