JDM and ADM t-50

[aaron_drift]

Hey guys + girls,

Quick question. Does the JDM and ADM T-50 AE86 gearbox have some number of splines?

Cheers

Aaron.

yeah its exactly the same box apart from the bellhousing and the speedo drive gear

above is correct...plus the Late jap box internals are different to the early model ones...still same spline though

[aaron_drift]

Thanks,

yeah i was curious, i "heard" the internals where stronger on the JDM box. Thought spline size may have been different.

[rthy]

stronger? no its just a myth.

Meathead #1: thats news to me

Ic, ratios are different correct? Big difference is clutch slave on opposite sides.

[rthy]

no the main part of the gearbox is meant to be tottaly identical apart from that plastic speedo drive gear (because of the different diff ratio)

[federal]

ratio's between adm and jdm are the same, they are the same strength, the difference IS the clutch slave on the drivers side, as it was built to run behind a cross flow motor with the exhaust exiting on the passengers side, and so the clutch slave was placed on the drivers side to keep it clear of the heat from the exhaust....

much in the same way that the adm bellhousing has the clutch slave on the passenger side being designed to run behind a non crossflow 4a with the exhaust exiting on the drivers side....

Makes valuable sense.
