Hi thanks for looking at this post. I have a built d16z6 turbo. vitara, Fjt rods, 59300 cam supertech valves, springs, retainers. garrett T3 42/48 60 trim. Any ways I dynoed it at 305whp @ 22psi but wouldnot hit v-tec on the dyno, later found out in was due to oil pressure. changed oil, changed to oem oil pump, checked pickup, changed all rod bearings (all .0015), changed all mains to (.0014-.0016). Turbo inlet has a restrictor. The gauge reads 55psi cold and drops to 15psi at idle, BUT still will only will build to 25- 30 psi no matter what rpm you take it to. thanks for any help
