I have already checked for boost leaks and I have not found anything. I am still using the same plug with stock gap from before I boosted the motor.
I know how you are supposed to get into timing mode but it wouldn't cooperate. The plugs that are in there now are NGK platinums. If those won't work then what would you suggest? The only sensor I have had trouble with is the o2 sensor. I have been given a very broad list of suggestions on what should work and two of which have not made any difference. That is why before I try the last one and waste more money for another sensor I wanted to see what else could be the problem. I have wondered for a while now if it might be the o2 sensor but other people "in the know" say that isn't the problem. It's interesting that you bring up the coolant temp because the car runs a little hotter now according to my stock temp gauge. Instead of being in the middle of the gauge it a little further to right. Not apparently in danger of over heating because I have driven about 2000 miles since the install. How do I make sure it is reading the right coolant temp?
Is the bkr7e an ngk plug? I will have to try and re-check for a boost leak somehow. The only way I have to monitor temp right now is the stock gauge. But I have also wondered if some of that may be due to the fact that I still have the ac condensor in the car. I am planning on taking it out to allow better air flow to the stock radiator. I will most likely purchase a koyo this summer.
Platinums are fine if they are the correct heat range. I ran plats in my car for the whole 150k miles, of which the last 80k were boosted, with lots of road course time. Plus, you can generally run a bigger gap with plats compared to coppers, so you should get better gas mileage. I changed them roughly every 40k miles, and even that was a little bit of overkill. If you keep the boost down and only daily drive, you can get away with heat range 6. For more serious driving and more boost, use heat range 7.

The stock temp gauge starts to budge somewhere around 110F, is at 1/3 at 160F, and doesn't move from 170F-220F.
Do you have anything to hook up the to the car to see what it's doing? Techtom? Cable for Nissandatascan? Calumsult? Being able to read O2 voltage, coolant temp from the ECU, MAF voltage, etc, are invaluable in trouble shooting.
I know the car can be a royal pain to get into timing mode, but it can be done. Like I said, search the se-r.net mailing list archives. If anything, just check the TPS and reset the TPS idle memory, it's free to do
Also, did you get the 300zx tt or Nismo radiator caps? (1.2 or 1.3 bar IIRC). They'll improve the cooling system, less chance of overheating.
Opps... I mispoke. Plats SHOULD be gapped bigger to attain the same spark power.
I learned stuff after the first wave of guys to do anything. I learned about turboing our cars from that first wave of guys like Mike Gossilin, Ben Davis, Jeff Nayert, Mike G., Jody M., Julian Hancock, George Roffe, and a handful of other guys. Back in the day, everything being developed was still new, so everyone communicated together to figure out what worked. Even with the help of the 1st timer guys, I still ran into a few issues, but those guys had figured out about 85% of it already.i had an issue with my 200 and after accidentally disc the o2 she ran like a rocket..so $63.56 later i have a new 300zx o2
its members like u that make me read up more info on cars everyday:tongue: ..sometimes on sat/sun mornings while fighting a hang over and sipping on some green tea figuring out how to make my car more reliable or whats the next to do mod list..i have only been in the sr game 5 years but after the second year u realize what works and with det's u need all the info u can get...either way cheers
