1. std timming should be set to 15deg btdc i believe.
2. fuel pressure should be bout 36psi according to the manual
3. std boost is 6.3 - 7.1 psi or on the silvia gauge 48 ish kpa (gauge is x10 so 4.8)
4. std is 135bhp cant remember what rpm that is.
5. i would wind up the boost without one, or you get detonation, and a holed piston.
hope this helps.
