I just put one in my 97 GSR. Make sure you get the R half shaft, starter and flywheel. They're lighter than the GSR's. Also, swap in your GSR's 5th gear unless you like cruising 4000 RPM at 70 MPH.
Don't get the 98+ JDM spec for your daily driver!
If you're doing this yourself, you'll need a tranny jack, a 10mm 12pt socket, a 17mm 12pt, a breaker bar and/or impact,a 32mm socket, some pry bars, a whole set of deep and shallow sockets, cotter pins, a 2-arm puller, silicon grease, axle grease, a punch (8mm if I remember correctly), as well as all the regular mechanics tools. I'm not sure if you need any special tools for swapping the 5th cuz I haven't done that yet.
And you'll need to know how to pop Honda ball joints w/out crushing the threads. PM me for that.
