I have a 1993 S10 Blazer with the w code vortec engine. Is it possible for me to upgrade to the MPFI spyder?

No. Your current PCM operates a single electronic fuel injector fired in batch mode to supply the engine. The MPFI system utilizes 6 individual injectors in sequential mode, firing only when the cylinder they feed requires fuel.
