vacuum trick
.
Just one thing I'd like to mention... regarding needing a fuel pressure regulator for an intake and exhaust mod.On 90 - 94 Protege'/323 you can disconnect the vacuum hose at the rail
fuel pressure regulator. At idle (intake vacuum high) the regulator provides 30 - 40 psi. At high rpm (vacuum low), it regulates 37 - 45 psi. With the hose disconnected you will "trick" the regulator into supplying the 37 - 45 psi all the time. Just be sure to plug the vacuum hose and don't forget to reconnect it when it's time to test for emissions.
