Yeah I'm pretty damn sure they did'nt make one. The old boy has one and we looked every where. Mechanicaly they are the same as the ST141 so just pick up a Gregory's or similar manual. As for the engine manual it does not exist. The best I could do was a supplement manual from Toyota but thats was for the 22RC. It has everything bar the fuel injection stuff. If you can do better than this then get back to me with details.
