I say check it with a an actual oil pressure gauge. If its still low then change your oil to something heavier until you can find the cause. If I remember correctly, there is a bolt on the bottom side of the oil pump that houses the oil pressure relief valve and spring. You can pull the spring out, stretch it out a bit longer, and reistall. Of course, a clogged oil filter could also be the coulprit. Whens the last time you changed the oil/filter?

Sorry, but I'm looking for an engine wiring diagram, thats body electrical. I'm looking for a diagram that contains the CAS, injectors, ignitor, coils, knock sensors, and the other bits of the engine sensors and actuators. Do you know what I'm talking about and where to find that?

Do you think you could send that to me too please?

I want to see more! Im actually doing this same thing. Im using trumpets but am going to make the very outer tip of the trumpet flush with the plate instead of sticking out into the plenum. Its like what your doing but with less machining......hopefully. Are you putting yours into a 180sx? Im wondering how far mine can stick out without hitting the strut tower and giving me good clearance? Very nice job on the tig work too!
