Does anyone know how to tell the difference between S1 and S2 RB25 gearboxes? My gearbox should be a S2, but Id rather confirm when its not in the car. I have searched, and didnt really come up with any answers.
Which leads me on to this; clutch slave cylinders.
R33 up to 06/94: [30620-21U01]
R33 07/94 onwards: [30620-21U23]
However, the NISMO slave; [NISMO30620-RS580] says:
- Nissan Skyline BNR32 (-2/93 Push Type)
- Nissan Skyline HNR32
- Nissan Skyline ENR33
- Nissan Skyline ECR33 << No dates specified
- Nissan Skyline ENR34
Because it doesn't have a date on the ECR33, is it suggesting that the NISMO is the same for both? But the NISSAN ones are not the same?
Thanks in advance
