I currently have a GSR swap in my 94 civic hatch and I am about to go pick up a rebuilt GSR tranny and a CTR tranny with a 5th gear that pops out from a family member that has had them sitting for the past 8 years for 200 bucks. I am thinking that I want to use the CTR tranny since it has a LSD but I do want to install a LS 5th gear. I haven't been able to find a definitive answer as to the parts I need to purchase in order to do so? Thanks in advance for the help. Trannies and electrical are my weaknesses when it comes to cars!!!

 

You will only need to replace both 5th gears from a Hydro 94-01 Integra LS.
