Power Fc Failed To Start

I found when mucking around with a friends RB26 power GTS-t when he bought a D-Jetro for it that it wouldnt fire up. We managed to get it to fire by removing the CAS, turning it with the key on and then putting it back in and starting it (we were actually checking fuel and spark were working fine, obviously the extra fuel in the cylinders was enough to start it). After it fired it ran, and I messed around with the tune to get it to idle fairly nicely.

But after this it wouldnt start again.

Have since been told that the D-Jetro base tunes are woefully out of wack in some points which I didn't think would be the case. My old RB25 Power FC could be started, run and driven (gently) with the base tune no problem.

If what I've said in the first post sounds about right and you have only been trying to start it to check it out then it may be a tune issue

Some things to make sure are done first though - Have you changed injector settings (if running different injectors to stock only)? Is it running MAP sensors? Are they selected (think they are by default but cant remember)? Are the MAP sensors getting a vac/boost source from the correct spot?

Start simple and work your way up. I'm guessing you have checked Sensor/SW check for any faulty sensors etc?

Which FC version are you running? L or D jetro?

If the previous tune on there is running quite different variables compared to your car then most likely it would struggle to run after starting. You will need to revert back to a base map on the ecu or something so you can at least start the car.

      Unpeeling the Orange

      If I had "perfect R33 GTR" kinda money I would have bought one of the crazy expensive low mileage HJA cars, but I am sadly not that wealthy. I already picked this car out of various Skylines for sale locally, most of which were worse in some way. Only a few cars were actually better but also more expensive. In terms of buying a motor locally, I at least have the option to inspect it myself and juding the seller as a person, and used or freshly rebuilt engines that some people sell are actually ok price-wise. I knew the car was going to require work, but shit piled up real fast and I haven't even driven 1000km yet as the turbo started oiling like a bitch within a few weeks after I got the car.   I assume it wasn't actually me who cracked it, though there is no way to know when that crack formed and if the previous owner even knew it was there. Buying another 05U Block can be a gamble, yeah, but the cheapest PRP cast block is like twice or more money-wise, and billet is 3 or 3 times as much. For now I am most likely just keeping the current engine, as a rebuild or engine swap isn't happening right now. But I am seriously considering buying a second engine and selling mine in return. Might be a sweet deal at the end.

      RB26 turbo oil banjo bolts

      By sunsetR33 · Posted

      Hi all. I need some help buying the correct size banjo bolts for my 2860 turbos. Because whoever installed them tore up the original part, I ordered new ones of this kind, because I just figured these were the most leak-resistant option as I already had trouble with a shitty braided line. I need to know the thread size of the smaller left hole, that is the turbo oil feed connection. I found out so far that the turbo oil inlet apparently has a 7/16"-24 thread, but I cannot find any listing or description of the thread size on this line. I do not have the original bolts. I tried using the bolts that were in the turbos (the ones that were mounted with the shitty braided line) but they sit very loosely so they can't be the right thread. Means either these bolts are the wrong ones (how do they fit the turbo then? no clue) or the wraparound-lines have a different thread than the turbo oil feed itself. Help is appreciated, asking Nissan directly is obviously not going to work.

      EDIT: PSA to whoever stumbles upon this thread. It is in fact a crack in the block that caused this concern. Just letting you know. In my case, a few cm long hairline crack going horizontally above the turbo oil feed. Classic RB shit I guess

      Might as well pop in some cams, head gasket, head studs, and a flex sensor. Full send.

      Yeah I spent close to a year finding one. I was even tempted to buy a RB25DE N/A head and port it out. That latter option, could still be an option.
