Has anyone ever put a any year of ATC 200x engine in a 1986 200SX frame?

 

arent they the same?

 

Not a good combo buddy, a better idea would be a 250X roller. They are a perfect mate for a 200X motor. Trust me, I've done this conversion. The SX frames are too short of wheel base, and without a hub change, you have to run the stock 8" front rims, thus limiting you to your tire selections.

350XX, 250R, 200XX, 450S, 300 2WD

 

See I have a full running 200SX.I just want something with a kickstart (and Possibly a clutch) Do you know of anything that will bolt on pretty easy.
