I found unless you are pushing well over 500 hp it's not worth it. I forget the flow rate but it wasn't that much difference. The 240 guys buy them as a major upgrade for their usage, but for us it's an OK mod. I remember that guy that was sponsored by TIEN (the white on in Turbo mag a while back) had one and used it as an upgrade. When I asked on the this forum about it, I was told just about the same thing that I am telling you. Unless your pushing well over 500hp it ain't worth it. In tech, it says the stock fuel pump is good for about 750hp but I don't know about that. I always wanted to know if the LSD was an upgrade for the 300zx but no one ever answered that post either.
