    speaking of which, we just watched deathproof on the weekend. also on topic, oil pressure is affected by main bearing clearances just as much as the oil pump. Ultimately all of those aftermarket vendors just took OEM solutions from other cars and applied them to RB applications. Only 1% of cars out there actually need more than a standard or n1 pump on a long nose crank anyway

    To answer directly, no, I don't know how they physically achieved the reflash of the ECU. However, the change in tune from factory is minor and unlikely to be your issue. If it is misfiring as it comes on boost it is likely to be some issue other than the tune. What boost is it hitting just before it starts to cut out (might be overboosting due to a boost control issue), or perhaps just an air leak somewhere.

    To be fair, even the biggest aftermarket suppliers do only a fraction of the engineering and testing of Nissan OEM, and they have to do so without understanding every other component that their aftermarket stuff will be used with.

    Yeah an at idle problem might benefit from more water flow, but as you mentioned fan airflow is the place to start followed by radiator volume and radiator air flow (shroud on fan and sealing air leakage around the rad)
  5. Duncan
    Firstly, no I have no direct experience with these water pumps. Having said that for track/race use with sustained RPM, I would never be looking for more blades and more flow. Consider a street car probably has 1500rpm average and a race car 5000rpm+ average I run the N1 pump with greddy oversize pulley and water temps are good, even on long runs on hot days.

    They are your parts, so you might get a strange look but it's a valid request. I've known some places in the past that keep and show all the parts they remove to build trust (not that most people would know if it actually came off your car, I guess you are safe with GTR heater hoses...)

    yeah sadly, looks good to me to. Do you have a decent pic of where the balancer was when you checked or did you find TDC through cylinder 1? If all 3 marks line up properly the timing is right. You can't be less than a tooth out, the belt has fixed teeth with fixed spacing. You can get a feeling for whether the tension is right with the cover off, you should get a cm or 2 but no more at the middle of the longest belt run I can't see anywhere you said which car it is but I understand all the GTST are 15o base timing and you said you checked that with a lead on 1 (important because if you use the loop at the rear of the motor, some guns read double timing which means 22 could actually be 11...)
  8. Duncan
    Thanks for coming back with the solution, good to know it happens sometimes
  9. Duncan
    I know you said you went back and the shop checked it again, but 99% this is a timing belt alignment issue. Perhaps they just made the same mistake twice because they are not familiar with the car Unfortunately it's tricky to get pics with the right angles to check, so maybe just get another shop to have a look at the car. It could also be a big air leak or fuel pressure issue (or a million other things) but what you are describing with the popping, running OK under low but not high load and just no zoom all point to badly retarded timing

    The current system is more painful than the previous one but still possible, I've got it on my GTR but these days you need an annual inspection by one of very few inspectors. Historical/Club rego is a much better choice if you qualify
  11. Duncan
    Yep, and if they don't break it, get it put back in again before the car leaves. Windscreens are a pain to transport safely
  12. Duncan
    glass out is best done by mobile windscreen guy, even then 50% chance they will break it.
  13. Duncan
    Hey, I just fixed your typo
  14. Duncan
    He is always willing to help out, comes at a price though
  15. Duncan
    well my thinking is they make a big difference to feel and predictability when they are right, and it is hard to impossible to change on the car. Given it's for track use I'd take the time and money to do them while it's apart to save having to chase some weird handling issue in the future
  16. Duncan
    you definitely want to do them now, particularly the toe/hicas one. If you aren't getting a 20t press try local shop to push them out
  17. Duncan
    your friend's a drug dealer? actually I said the same to the neighbour's kid when he turned up in one. went down like a lead balloon. turned out he was.
  18. Duncan
    yes sorry to say, replacing all coolant hoses is a pain with lots of parts and probably lots of old, seized clamps, it would take a few hours
  19. Duncan
    jeebus mate, look after yourself....none of us are backwards cap kids in r33 gtst s anymore Plus, I'd really miss your stories about buying a car to leave it stock...
  20. Duncan
    They don't survive abuse bwith big power and a lot of AWD, but 285kw should not be an issue. I'd be looking for any sloppyiness between the driveshaft at the xfer case all the way to the front hubs, I think something is moving that is causing additional shock and the diff is the weak link
  21. Duncan
    well, vk56 is the go but I guess it is kind of a v8 sort of
  22. Duncan
    Welcome to SAU! Is Berra a typo and you meant Barra, ie the engine in most taxis in Australia? If so, I think there has been a couple of people with R chassis swaps, but have you checked physical space in the z engine bay as they are a very long motor?
  23. Duncan
    yeah it's nice for the water to go straight back where you source it...have a look at solar pumps and it could run any time the sun is up without needing to keep an eye on it
  24. Duncan
    What bloody summer, it's 1o here this morning. I knew Global Warming was a conspiracy to reset the world economy by skinsuit wearing lizard people who unleashed covid via the 5g towers Also....it's not instagram unless you show us pics of your welds. I somehow forgot to take any pics of the repairs I did to the slasher a couple of weeks ago
  25. Duncan
    do you have any way to get a fuel pressure gauge on the system? my guess is the pump is simply dying. if you don't have something any decent mechanic should be able to check static fuel pressure for you. re releasing pressure when you open the cap, this is normal and fine. The cap should be vented to allow both air in as the tank empties and air out if the tank heats up and the fuel expands, which you might notice most during spring as the weather gets warmer (not that I know if it is spring where you are, there is no location on your profile :))
