I don't believe so, but I'll let the more experienced chime in.
However, you can use a 944 or a 951 radiator (as the chassis are pretty much the same aside from some bracketry) and even the matching expansion tank if you'd prefer:

951:

BTW, the stock single fan unit used on the 924's is really ineffective. If you keep the stock radiator, I would upgrade the fan unit to help keep the car cool and save your head gasket. A 924 Turbo radiator and radiator fan are a direct drop in.
