3-tc T50 to 4AGEDO

[Drift_725]

Does the T50 out of a t18 with 3tc bolt on to 4age? I am not sure of the bell housings are different.

Tim, pretty sure that they are different.

AE71 T50 is the one

differant bellhousing and spline from memory..... Adaptable, but not really worth the fuckaround

[stahlz_ae86]

Series two T-18 (plastic bumper type) has the same tailshaft spline as AE71 and AE86. Early T-18 (chrome bumper type) has a couple less on the spline count for the tailshaft. Both types of T-18 box will require either an AE71 or AE86 bellhousing to mate to a 4A engine.

Shifter position is different also ain't it?

Are T18 boxes alloy?

[Hen may possibly be a nut]

From what I've seen and read there's 4 main "types" of T50:
- TA22, forward shifter, T bellhousing, 20 spline
- Early T18, rear shifter, T bellhousing, 20 spline
- Late T18, rear shifter, T bellhousing, 22 spline
- AE71/AE86, rear shifter, A bellhousing, 22 spline (only difference with JDM AE86 is location of the clutch slave).

There are also some internal differences (eg, I couldn't swap 2nd gear from a T18 box to an AE86 box as the centre bore was a few mm different), and something about a change of the input bearing through the years but these are more minor.

And yes, they are all alloy split case boxes.

You may have just shattered all my dreams of finding a cheap layshaft...
