The 300zx TT comes from the factory with a 650+hp fuel pump. There are many "performance" fuel pumps, like the popular walboro 255 that are smaller than oem. I realize you have a conversion, just pointing out that the fact that you don't know what you have is a concern at your power level.

Putting AMS garbage, and $500 ebay wheels on a Z is like dressing a Victorias Secret model in a Walmart dress and Payless shoes. You're embarrassing yourself.
