Thanks guys for all the help and advice.

 

you don't need much to work on the s2k. basic sockets you'll want include 8mm, 10mm, 12mm, 14mm, 17mm, 19mm, 24mm (diff drain) and 36mm(axle nut). 23mm wrench (diff fill). 4 or 5mm allen key for the spark plug cover, and a 5/8" spark plug socket for those with a long extension.

that's pretty much it, no specialty tools for anything common. basically all you need is a metric socket set
