my car stereo remote batteries probably have more power than that. optima batteries are very good, but you pay for it

the only reason it was put on 15psi was to check if it would cut out, but it ran on 15psi without cutting out, it also did 240km/h on the dyno, both these things i've been told a standard ecu would not allow. any reason in getting the front mount before the ecu? except to avoid double tuning?

ECU is standard, but it has been modified for the boost cut and speed limit afaik, it came from japan like that. A new ECU is on the cards but probably after a fmic and forward plenum. Thanks for your advice R33silverS2

Spark plug gap is 0.7mm car is definitely not running lean, the o2 sensor is not plugged in, its stuffed anyway. It is very very bad on fuel considering it's standard except exhaust, bov , boost controller. Spark plugs were originally not correctly gapped and it did have problems misfiring and what not at about 5k-6k rpm, after the regap it fixed the problem. Not sure if I've noticed the problem on low boost, however that defeats the purpose of spending 900 bucks on the boost controller, of course more mods to come as money allows. It's getting some new mags on Thursday and getting plugged into a diagnostic computer to check for errors, I'll post the findings on here once I know. any help is appreciated!!!

after taking the car to protune, we learnt that it was the blow off valve thats leaking air and making that sound. however the jerking is quite something else, he said he's pretty sure its not the coils or spark plugs as the whole engine completely stops for a second, sometimes the wheels screech, however he did put it on the dyno and on 15psi (he was checking if it had a boost cut, which it does not, neither speed cut) it made just over 190kw at the wheels. but still no idea on the jerking, it can be so violent its like you're about to go out the windscreen. also the car is running normal oil pressure and the oil and filter was changed not so long ago. fuel filter and spark plugs were also done, and they were correctly gapped. If you guys have any other ideas, I'd appreciate it, don't want to have to send it to nissan (just yet) and cost an arm and a leg.

the time it takes for the solenoid to click on and off depends on the circuit resistance, you should replace bulbs with the same ones it came with, or at least the same resistance, a low wattage bulb will be higher resistance

the solenoid had a rubber mount put behind it to stop the sound, we took the pipe off to the turbo, there is no play up,down,left,right, only a tiny bit back and forth like you said, the exhaust is complete back from the turbo, there is no fmic (yet) the car has just done 120,000kms. after the rubber mount was put on the ticking and scraping sound went away, but since i got it back it still felt like it was lacking boost regardless of whatever the boost gauge was saying, but now the ticking and scraping sound is back. but after taking all the piping off and checking the turbo shaft it seemed to be ok for about 1 week now its ticking again and making a squeal/scraping sound i took it down the motorway in 3rd and u can really hear it it gets louder and faster as the revs climb, i've been doing a bit of reading and some people say that sound could be a blown gasket on exhaust flange, but im not sure. it only ever started doing this problem since the guy at ***** adjusted the blow valve tighter so it wasn't so loud and wouldn't blow off much, because we thought it had a vacuum leak because it stalls sometimes, now we think its the afm but thats another problem, also the other problem is once its boosting it jerks so violently u almost hit the windscreen, once it even left tyre marks on the road, this jerk can happen at as little rpm as 2,500 and all the way up, its incredible annoying and definitely cant be good. car has not been dyno'd yet, we're afraid if it jerks it on the dyno something bad might happen again sorry for the wall of txt

bump... someone has to know

hi i have a R33 GTS25T 1996 series 2, the motor was standard and I added a boost controller profec b2 and a blow off valve, also the exhaust is not standard, it came from japan it, its a pretty decent exhaust, anyway after the mods were done and running the car on 13psi it started to making ticking noises when the turbo was spooling, we took it back several times and finally they came to the conclusion it was the solenoid for the boost controller, however the car was also making a squeal/scrape sound along with the ticking, it would also jerk a lot, like fuel cut or something, and even though the boost gauge said it was boosting it felt like there was no boost at all, changing between high and low didn't really do much, the ticking sound has come back along with the scraping sound, after it had 'already been fixed' i appreciate if any of you guys can help me with this problem sorry for wall of text
