guys i just changed my engine oil to motul 4100 with rating of 15w50. After that the car feels more quiet but the problem is i normally warm up the engine about 5 minutes before driving but it has the tendacy of stalling and i noticed that the fuel pressure from the dash is kinda low:it will only stall if meter is pointing at 2. If its between 3 and 4 its fine.The normal level of oil pressure would be between 3-4 right?(during idle)

hello, i just got my R33 BNR33 and it is slightly modified with fmic and hks bov, lighten fly wheel, racing clutch and fuel injectors. I am a newbie to turbocharged car and there are a few questions that i need to seek advice from the nice people here. Below are my questions, would appreciate if anyone is kind enough to answer my questions. 1)I do not have any aftermarket oil pressure, boost level or oil temp metres on my car, can someone enlighten me what are the normal value for these readings on the R33 dashboard? 2)I installed an IES GSM alarm on the car, ever since then my turbos are giving some sort of a grinding sound whenever the rpm is below 2k. It sounds like the fins are "spinning and gridinng on something". It sounds normal at higher revs(3k and above). Is this normal?(The sound is most noticable from 1.8k to 2.8k rpm and pick-up seems to be slow, at 3k boost everything is fine and i can feel the boost) 3)what is the stock turbo for RB25DET? 4)What kind of metres should i get for my skyline?eg:voltmetre, boost meter,oil pressure etc (not for show offs, just want to make sure my car is healthy) 5)when they say change their fluids, eg: brake fluid, oil fluid, lsd fluid, bla bla bla, what kinda fluids are there to look for?(sorry, complete idiot here)

its just a simple question and am waiting real time in office for an answer. sob sob sob =(

I've done a lot of read up in the DYI section and i must say you guys are fantastic. While reading across those thread, "flat spot" topic keeps popping up now and then. I would like to know what exactly is a "flat spot"? I am driving a R33 but my car jerks if i don't warm it up properly but if i did, everything seems to be fine. FYI, my R33 is light modded with: ARC FMIC single plate racing clutch and flywheel denso iridium 8 plugs adjustable suspension actually all these were done by the previous owner. any idea why my car could be jerking if i do not warm it up properly?(at least of 10 mins warm up)Could the plugs be too "cold" for my car or is it some other problem. and please do explain what is "flat spot". thank you very very much!
