98 EJ25D w/ 97 Impreza L Trans & Clutch Question


Recommended Posts

Clutch is fine. Everything is the same and will bolt right up. Different cars came with different final drive ratios and that must be a match between the trans and rear diff.

 

The general rule is that Legacy Outback , GT and Impreza RS are the same (4.11). And Impreza (Non RS and Legacy non GT or Outback) are the same. (3.90)

Match the trans codes to the chart to see what yours is and what potential donors are. Gearing can be different but the final drives must match. Or swap a matching rear diff as well.
