Yes it would. You just need the right PCM and it sould work fine

Well how about the fuel pump and the cluster? wouldnt work with a newer cluster.. things dont match up..

I'd say get the obs, put the SD turbo/uppipes/plenums/ic/hpop/fuel pump, then you're set. im assuming you have a bad motor, take the good stuff off n upgrade the obs motor...

Treat the OBS motor as a short block and swap everything that is different, including the injectors. Plug the mechanical fuel pump hole with a 7/8" freeze plug. My 2000 is running with a 97 OBS engine donor.
