One of the easier modifications you can do is install a short shifter. It is easily one of the single most obvious upgrades in that you’ll be using the shifter whether you are at the track or driving to work. There are many aftermarket shifters available. I chose the B&M shifter because it offers one of the shortest throws. Most of the alternatives are very similar in design and throw reduction. Stick with a brand you trust and you won’t have any problems.

This process works for any Honda or Acura that uses a rod shifter. While doing this project, you may want to consider installing upgraded bushings for the linkage since everything will be easily accessible.
Start by raising and secure the entire vehicle.
At this point, you need to determine if you want to completely remove the shift linkage from the car. It isn’t necessary, but it is easier if you pull it all out. If you do not want to remove all of the linkage, skip to removing the bolt that attaches the shifter to the shift rod.
At this point, you need to slip the linkage and shifter back into the car (if you didn’t remove all of it) or attach the other shift rod to the bottom of the shifter.
Slip the shift linkage back into the car (if you took it all out) and attach the linkage to the output on the transmission and attach the shift linkage with the bushing to the side of the transmission.
For the most part, installing a shifter is relatively straight forward. You may face rusty bolts which tend to plague salt belt cars. It may not be a bad idea to have fresh nuts and bolts for the shifter retaining plate or the hardware (Sleeve, o-rings, plastic inserts, and dust seals) for the lower pivot.
