Im after an oil pumpformy gtrand dont really wnat to spend the $1700 or so for a nitto, crank collar and machining, I know rb30's have a different geardesign, narrowdrive and dont seem to crack, however theyflow less. Im planning on running restrictors on the head feed, and a single turbo, which will both improve oil supply to the bottom end, am I mad?

Yep. You are mad. lol

Simon-s14 has a stock na bottom end with stock shimmed pump with 26 head in a drift car. But he is risking a stock sh rb30 bottom end so like 300bucks max.

weigh up the risk and decide

Just got on CT and found that heaps of people are running a8(turbo) pumps in big hp/8000rpm cars running down to 9's, just never heard of vls breaking pumps, seems to be a skyline thing. If simon s14 is running a stock na pump, then it would have even less load onthe drive flats, as they flow even less, wonder what his oil pressure is like

Don't forget though they are all auto, leave the line off a loaded engine/transbrake and you never see them sitting on limiters during burnouts. Definately big factor differences.

It's certainly not the RPM that's the problem on a well balanced motor.

Where did you get $1700 for crank collar and install from? The collar itself is $150 and I had a wide crank collar fitted to an rb25 crank for a little over $100. Even if having the crank micro polished, straightness/crack/balance checked and grub screw cleaned you'll come in at well under a grand.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      R32 GTS (RB20DE) Injectors Replacement

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
