i have been having some problems with the car lately , i did a full tune up with all the good stuff brass cap, rotor, ngk wires ,ngk 7031 plugs gapped to .32, ntk o2 sensor, timing at 10* and did the tps reset,and its running good under part throttle but under boost i get a hard mifire 3500ish rpm then it accelerates to 5k rpm and starts to break up.   . i have had 2 different sets of injectors and its done the same thing. i haven't had the time to check fuel pressure yet but the regulator is

fuel injector clinic stock replacement injectors , i only put 1000 miles on these and i replaced them with good stock injectors.   they did make my car run alittle rich, you might want to have them flow tested but they are the 650cc and 950cc injectors.   have paypal,   $150 shipped   http://i134.photobucket.com/albums/q104/Drift_300ZX/001-1.jpg http://i134.photobucket.com/albums/q104/Drift_300ZX/002-2.jpg http://i134.photobucket.com/albums/q104/Drift_300ZX/003-2.jpg

I replaced the 12a in my flatty with a 16g DSM turbo. The car is less a aggressive and less fun and doesn't seem much faster. Do I need to turn up the boost? 12a was at 10.5psi and the new 16g is at 12psi. The A/R on the new turbo is .70. My exhaust is 2.25 through a glasspack and out the back. I know its a bit small... I have a Widebody FMIC I think its a 16 row not sure tho. Fuel cut eliminated in the ecu. Car runs good. Possibly do I need to run more timing? I run non-ethanol premi

Hey:   Im looking for a good 12A turbo for a buddy. If you have one to sell, PM me please.         Thanks Jeff
