I have a 92' integra with 155,567 miles on it. I am pushing 8psi daily on stock internals and never did a rebuild. Just make sure you have all the right fuel properties so you don't BLOW UP. I recommed 10:1 Vortech FMU, 350cc injectors, and a new fuel pump. YOu also need a missing link sensor or you can make your own check valve system.
