S13 - Auto or Standard

Is there any difference between the auto and standard s13s? im looking at buying an auto and converting it to standard. Is it possible?

commmmmmmon people, someone should know!! this depends on me getting a silvia from japan or not!

YES it is very possible. My son just did this conversion on his buddy's car. His biggest glitch was the fact that the automatic makes it impossible to start unless it is in park. He had to find which wire to divert. All is great.

AWESOME!!! Because im getting a auto s13 so i wanna swap out a tranny because this one is dirt cheap and i cant pass it up!
