Quick question.

Will a ps pump on a '00 LS work on a '94 GSR 4dr?

 

I'm not 100% sure if this also applies to teh B18B engines, but you can't use a newer pump on OBD-1 cars without a '98+ high-pressure line. The high-pressure line is the one that runs alongside the valve cover. It's a $100+ piece.

 

I can't 100% say yes but I don't see why it wouldn't.
