Not a good idea. Turbo motors have many different modifications to take the additional stress/power of the turbo. Piston oil cooling jets, hardened crankshaft, etc....all critical to the longevity of the engine if it has a turbo. A N/A 240 engine has none of this....so you'd have problems. Also, it has no boost/alda fuel device on the injection pump. So getting it to add fuel properly based on boost would also be a big issue.

Overall it'd just shorten the life of the motor significantly, I'd not do it. There is a company in India that sells turbo 240 engines with all the proper modifications for it.
