I went through this a while back. There are not many aftermarket Hi Flow water pumps made for the 94-95's. Edelbrock does not have one, nor does Moroso. I ended up going with Flow Kooler's (not sure of model #) hi flow unit for our cars and it works perfectly. I got it from Summit. It flows somewhere around 35% greater than stock, and has a flow reduction at higher rpm to prevent over pressurizing. I think it was like $125 and I'm pretty sure it had a lifetime warranty, but dont hold me to it.
