Did it have the S20 or the S40 sticker on it? Did it have P20 stamped in the bell housing? Maybe it no longer matters... just measure what it does on the road.

It sure sounds like you have one of the very tall final drives.

It's an S40. That's the one thing I knew to look for when buying. I just went out and took a look at it. It's stamped P4A and the second sticker says E7F.

Yeah I had been referencing your thread. Very helpful, thanks! I was particularly interested in what years were drop-in compatible when I was searching and you had that info in there. Now I'm referencing it for the gear ratios. I still haven't come across good info on how to differentiate based on the outside if the transmission. According to Reference: Transmission Specs - ClubCivic.com - Honda Civic Forum the trans could be either of the final drives as an E7F just depending on the chassis.

I will say that I did not feel a difference seat of the pants but so many aspects of the car changed after the swap I wouldn't know it if it hit me in the face.
