I'm a 240 guy, and haven't really ever messed with the 850 at all. Are there differences in the engine internals between the NA 5 and the t5? I'm looking at buying an overheated '94 850 t5 wagon in good shape and swapping in a motor. A possible donor car is a '93 NA 850 that has body damage. Can I swap motors and just add the turbo parts etc? Thanks in advance for your thoughts.
