hey guys, finnaly after over a month got my r31 with the rb20det conversion done, got fmic ready but not on the car yet so its just piped direct from turbo to engine. i know it not good to run it this way but its temporary till i get my next day off. its been running fine, crept it home and to work hitting at most 1-3 psi most of the time spent in vaccum. then just as i got home, noticed it stopped producing boost, boosts up to 0 psi???? andy suggestions?? could i have fryed my turbo or should it be ok with no intercoooler driven gently???

Check all the pipes, maybe you've popped a pipe off somewhere...

THEY ALL LOOK GOOD, COULD THE TURBO BE STUFFED FROM OVERHEATING?? IF IT WOULD OVERHEAT DRIVEN SO GENTLY??

correction!!!!!! THE CAR IS PRODUCING BOOST OK, JUST TOOK IT FOR A RUN, BUT IF IM IN NUETRAL WHEN I REV IT IT WONT BOOST, AND I AM REVVING IT TO LIK 4 GRAND, FOOT DOWN 3/4 OF THE WAY BUT WONT GO PAST 0 PSI???, ONLY WHEN IM DRIVING???

Yeah dude you won't really get a reading on the boost gauge if there is not much load on the engine. The most you will get is about 1psi or so but even then you will still have to rev it to redline to even get that. If you have a atmospheric venting BOV you will still hear it vent though because there will be pressure built up in the intake.

      RB25 Oil Pump Regulator Washer???

      By joshuaho96 · Posted

      Weirdly I see a flat washer on aftermarket pumps but as you said it doesn't seem like new OEM pumps have it. EPC doesn't break out the regulator as a separate component either. I'm guessing if the pump came that way it's safe to use as-is.

      I'm always a glass half full kinda guy. This will be a great project and the finished product will be awesome.

      A local that insisted he learned from the best in Australia for RB builds managed to machine a head past the point of saving according to another shop and it dropped a valve too. Ghosted the customer and as far as I know nothing really happened to him. A coworker also recently told a story about owning a Porsche in Germany and running into issues with a dealer tech leaving scratches, oil stains, and missing parts all over his car. I'm not a master tech by any means but at this point I've seen enough expensive mistakes that I'd rather make them myself.

      Mistakes were made, my R34 Story

      12 months on the pump would be great! The pump is really not that old, I have a receipt from when it was purchased new and it's done ~25,000km since then. it really should be okay. And if it it's not, well. I figured I'd at least run it out as it's already tapped for the nissan temp sensor sticking out of it. Here it was, ready to make it's journey back into the bay, though the balancer had to be tightened/seated more. And it was very stubborn to sit back. So much so that the crank bolt ended up stripping inside the crank instead of the balancer moving to it's intended location.

      There are professional butt-monkeys too. Just from lack of familiarity in Europe and the US there are plenty of mechanics who do things the wrong way on RBs. Even here in Oz, where we've been playing with RBs since 1986, there are still examples of the not-quite-bright-enough mechanic doing the wrong thing and causing simple jobs to go wrong.
