I have finished turboing the ke20 and broke the star gears in the diff- While taking the Diff appart i noticed that the axles were huge (compared to my ke10) the axle actually steped up to the spline- not steped down. I brought what i thought was a ke20 axle as a spare and it steped down to the spline.
So is this a ke20 diff in my car or perhaps a ke30? it is still 4x110 and looks identical to the ke20 at the local wreckers. Removing the axles was a bitch of a job- the bearings were well and truely seised, so i dont think the diff in the 20 has been swaped recently.
