Change to Acura TSX 5th and 6th Gear
Here is the list of parts that we have found that you need in order to install a TSX 5th and 6th gear. These are longer than the standard RSX or Civic Si gears so you will get better gas mileage. We picked the gears from the 04-08 TSX because they are a touch longer than the 09+ TSX. This will also be the parts that you need if you want to upgrade your 5-speed transmission to a 6-speed.

02-05 Honda Civic Si | 0.738 | N/A |
