Ok I think you're right and I will buy a pump from a turbo model. I will update on what has happened. This forum has helped me a.l.o.t. and I want to contribute back. If anyone else has any input please let me know; I think I have made my decision on going ahead and buying the one from the turbo model. If anyone has any information about adding a turbo to a non turbo model please let me know! I've never done it but I do know that I cannot add a big turbo or a lot of boost because my engine was not designed for a turbo. After this engine goes out I plan on purchasing an engine from a turbo model. Thanks again in advance!
