ive recently put an rb26dett into my gtst. converted to rwd running a s2 r33 box. i sent it in to 1 of out tuneing specialists. they wired the the hole set up so it worked. then i took it back there and had it run up on their dyno. they re chiped the factory rb26 ecu. since its been sitting 4 nearly a year as it is not road legal yet ive been geting it ready 4 cert. ive since driven it a few times. put new fuel in it. found that under boost it cuts out. so i tried a new igniter and loom. still farting around. so i got rid of the coils and put in a wasted spark set up thinking it was a doggy coil. its still no better. it wont boost higher than 0.5 bar then seams like fuel cut or boost cut. but that has all been removed when new chip was written. the timing is all correct and hav brought up the fault codes and everything it working fine. cleaned afm and they r mint.

if any 1 could maby point me in the right direction that would be great

sounds like a nice project.

Have you upgraded the fuel pump?

also try a set of afm,s that you know work.

just because there clean it will not always mean they will work correctly.

that would be a good place to start i think

      R-chassis INNER tie rod torque spec?

      By hardsteppa · Posted

      Not sure if you're being serious? I, and all the car people i know, ALWAYS use a torque wrench for wheel nuts. I assumed any car person, apart from tyre centre monkeys with rattle gun in hand, would do it properly.  Anyway, no further reply from me on this unless legit discussion from OP or his query so, over to you, knock yerself out.

      I was wondering about this. I'll do some research.

      Why not? Since mines been built, I've used low boost maybe 5 times.

      gauge needle removal

      Yeah, so widen your search to any Nissan speedo first, then go wider if needed. I will say though, that there is a better than even chance that what I said first will likely come into play. They quite possibly won't come apart without damage. I tried to disassemble a stepper gauge that I wanted to repair. There was no way that needle was coming off the spindle, and I could not see how the spindle would come out of the mechanism behind. Assembled once, never to be disassembled, was my conclusion. Could be the same on the R34 cluster. Failing that - take the cluster to a workshop that specialises in automotive instrument work. There's usually at least one in every Australian city. They'll either be able to do it for you for small cost, or tell you it can't be done. It might be that "it can't be done" unless you follow some arcane procedure, including trickiness to glue it back together or something, that only experienced techs know.

      Well, given that I, an engineer, almost never bring out the torque wrench to tighten up chassis bolts, despite fully knowing the theory, and instead rely on feel, which I happen to know is exactly how the majority of mechanics do things, should tell you the level of actual peril that exists from not achieving exactly 88 Nm of torque. How about if I just say then that 88Nm is at the lower end of the correct wheel nut torque range? Everyone knows how to tighten a wheel nut, right? And almost no-one ever brings out the torque wrench for that task
