i have just bought a s2 rst as a non runner, the shell and everything else is in excellant condition, but apparently its been on/off the road with back firing probs, now i just bought it and started to strip it before gettin called offshore so have not done much with it yet but was wandering if anyone esle has had this prob or is there a common fault, i got as far as takin off turbo hoses inlet manifold and fuel distibuter(if thats what its called) and they were all manky with oil which led me to check the turbo itself, there is some up and down play in the shaft, the previous owner told me that the car went out with a back fire and has not started since, sound familiar????????? let me know
