Hi all.
I have made some tuning on my car and would like to share some of it with you all. I try to upload lots of pictures, some descriptions and information about where to find parts.
This is how I rebuilt a Z32 gearbox to fit my car (200sx S13 with ca18det).
Yes I know it is PS, we have winter here now, hence no photo...real thing in garage is further down in the thread
The good thing about it is that you can reuse the nice clutch you already invested in for your S13. I have a twin disc OS Giken clutch, bought for my S13 gearbox. Both gearboxes have the same dimensions on the ingoing splined shaft, release bearing, sleave etc. This makes it an absolute fit. The gear ratio is slightly higher. My car had before a top speed of 282km/h at 7800rpm. With the ratio of the Z32 gearbox and new tyres it will make aprox. 305km/h. Hope you like it.
Clutch: Same as S13 (clutch, bearing, release sleave, starter motor, flywheel)
Weight: A bit heavier because of internal dimensions
Length: A bit shorter (reuse the yoke from the Z32 and the rear part from theS13 and make a new, longer prop shaft)
Gear ratio: A bit higher (~5%)
Shift stick: Reuse the one from Z32 or buy a new short shift
Welding in cast aluminium: You need a TIG or go to a welding shop (sand blast the weld area to make it clean and easier to weld)
Z32 original gearbox from a Twin Turbo 1994
