s13 sr tranny

As the title say I need one s13 sr20det tranny.
Let me know!

use a ka tranny shorter gearing
just swap bellhousings

Only difference between a KA/SR Tranny is the Reverse Gearing which plays no part in the over all gearing. So, no a KA does not have shorter gearing…

The CA18 has the shorter gearing (5th gear & final drive due to the diff)
