hey guys just wondering if someone could help me out. i've got a r33 with s2 rb25det, 6boost, big garrett and making 400hp but on sunday i got up, started it was running good, then drove to the track for powercruise (wa) and was waiting in line on idle and it decided it had pro cams in it and startd idling lumpy then when i went to take off it stalled n from then on i couldn't get it started agen....... see my problem lol.

i checkd it yesterday and pulled out no.1 plug and it was dry after tryna turn it over few time and made sure it was geting spark witch it was and checked the other ones and they were wet but not dripping... but all getting spark and battery is allil dead but we had jumper leads on but still wouldnt start just turns over.... any ideas would be much apprecaited. cheers

As much as it pained me to read that short paragraph..

Ok so your either missing spark or fuel, the fact that your 2-5 plugs are still wet sort of tells you it's probably missing spark still, despite you saying it was checked. How exactly did you go about checking spark? Have you verified fuel pressure still?

Rip the feed line off the rail and check it primes with ign. I was going to recommend putting the ECU into diags to check for fault codes, but looking at the mods it's probably not running stock management anymore.

As often as it's said for it to die completely like that I would be leaning towards a faulty CAS at this stage, thats pending your answer on how spark was verified.

hey man, yeah we checked the fuel by like you sed pulling it off and turning ignition and it had fuel. we tested spark by pulling out the coil and plug and sitting it up and turning it over and it was making spark so im kinda thinking cas sensor to... but thanks for all ya feed back. so what you reackon? if it helps was in powercruise the day before giving it abit and then burnout comp that nyt.. but started fine in the mornong.. lol cheers ya help

Im assuming u have an AEM computer? a PFC or something ?

I had the same issue, fkn lumpy idle, guttless, and died. My loom was loose in my pfc ecu. Tightened up the screw and she was sweet.

    • Probably speedometer itself if the odometer is ticking. If the needle is stuck from a bit of grease or something that can cause it to stay at 0. Or a cracked solder joint in the speedometer can do it too.
    • Thanks Fella’s   to take this off topic and to elaborate a bit more. I have an rb25/30 going into a r32 GTST.. expected to make around 600-700hp. Would you?   A) R34 GTT box   B) CD00#?  I’ve seen a few posts about the CD swap and sounds fairly involved with making it fit etc but if it’s worth the work then I’ll go that way
    • Lower at the hubs. Funny I forgot to mention that part. Do this pull here I turned the camera off too soon but the graph shows a drop at the top and that was because the pipe from the turbo blew off. The tuner said we could’ve made possibly another 15 whp. He also added if I switched to ethanol we could up the boost some more as well. I was comfortable capping it at the most of 20 pounds. Turns out the turbo pipe just needed a new worm clamp. Got home replaced that then did a third gear pull from 3k to 7200 rpm and the power was great to the top. I just got an ecu mounting bracket from IEE that I need to try and get everything to fit well. It’s a PITA to get the harness and ecu fit properly behind that kick plate 
    • He means "as opposed to mechanical cable drive". Older cars (R32 for ex.) had cable drive. Later cars with essentially the same gearbox, ie R34 GT (NA RB25) used essentially the same box as the R32 GTSt, but instead of a cable drive, had an electronic speed sender plugged into the same hole in the box, running from the same little gear that would have run the cable. Some of the shittier later cars use a speed sender on the nose of the diff, or the ABS sensors.
    • Lower than engine, or lower than it should at the hubs? Either way, that is a nice power figure and I'm not surprised you say it rips now. What stopped you from turning it up any more? Injectors? Or did it just stop responding to boost?
