They are simple engines. There arent many moving internal pieces. A master rebuild seal kit runs 1200-1300 bucks and doesnt have oil control seals. The apex seals (rings for you piston guys) are about 200 a set for aftermarket "stock" seals. THe rotors (pistons) are 600 a piece, and the housings (cylinder walls) are 600 a piece. If there is anything wrong with any one of the 600 dollar pieces i just mentioned... this "cheap rebuild for a profit" could easily accelerate out of control. Do you need a 1300 master gasket kit? no. Lots of guys buy the gaskets that absolutely need to be replaced and rebuild their engines for about 700 bucks (including apex seals). Now keep in mind there are quite a few other, smaller, parts that will add up quickly like apex seal springs, corner springs, stationary gears, bearings, eccentric shaft, thermo wax... etc etc. If your not into the rotary scene... i would suggest just leaving it there as everyone else has... If you do pick it up, take it to lakeland on saturday night, sit it in the back of the truck at the track, and offer it "as is" for whatever you think you can get for it. Make it easy on yourself tho and leave all the accessories in the scrap yard. THey most likely wont be in working condition, and the guys at the track will have no interest in them anyways, so you might as well save the $.
