G day people I have a 98 gtt only owned it 2 months so I know nothing about these things starts fine idles fine but when I put the hammer down any where from 3500 to 5000 the power will drop out completely.. I thought it blew up .. But still is running... If I drive around just normally it's ok will only drop out when it feels like it have changed the fuel filter thought I might ask before I take it to the shop .. Standard intercooler and turbo 3 inch exhaust k&n air filter cheers

Hmmmm... I don't think anyone has ever tried anything other than oem coilpacks.

You know modification of r34's never really took off so I don't think there would be very strong aftermarket support for these cars.

Same on why there isn't much info about squeezing power out of them on the net.

great stuff. it's good practice to gap your plugs down to 0.8mm as well. Fresh coil packs should be firing no problem but reducing the gap makes it a bit easier on the ignition system.

you can buy pregapped plugs - BKR6E or BCPR6ES. Don't get the ones with -11 suffix, those are 1.1mm gap (and unfortunately more common). The ones without the suffix are 0.8mm.

you can put platinums/iridiums in if you get a good price but copper plugs are cheap and although you have to change them a bit more often it's good to have a look at them now and then (spark plugs tell a story about how your engine is running.. rich? lean? detonating? you'll see it on the plugs).

Say what?!

if they have -11 at the end then all you have to do is gap them down to 0.8.

If they are the same heat range as what is required then it makes zero difference!

I have gotten spark plugs that were meant to be gapped at 0.8 but were all over the shop, 0.7 - 1.0 on a batch of six

      I neglected to respond to this previously. Get it up to 100 psi, and then you'll be OK.

      I agree with everything else, except (and I'm rethinking this as it wasn't setup how my brain first though) if the sensor is at the end of a hose which is how it has been recommended to isolate it from vibrations, then if that line had a small hole in, I could foresee potentially (not a fluid dynamic specialist) the ability for it to see a lower pressure at the sensor. But thinking through, said sensor was in the actual block, HOWEVER it was also the sensor itself that broke, so oil pressure may not have been fully reaching the sensor still. So I'm still in my same theory.   However, I 100% would be saying COOL THE OIL DOWN if it's at 125c. That would be an epic concern of mine.   Im now thinking as you did Brad that the knock detection is likely due to the bearings giving a bit more noise as pressure dropped away. Kinkstah, drop your oil, and get a sample of it (as you're draining it) and send it off for analysis.

      I myself AM TOTALLY UNPREPARED TO BELIEVE that the load is higher on the track than on the dyno. If it is not happening on the dyno, I cannot see it happening on the track. The difference you are seeing is because it is hot on the track, and I am pretty sure your tuner is not belting the crap out of it on teh dyno when it starts to get hot. The only way that being hot on the track can lead to real ping, that I can think of, is if you are getting more oil (from mist in the inlet tract, or going up past the oil control rings) reducing the effective octane rating of the fuel and causing ping that way. Yeah, nah. Look at this graph which I will helpfully show you zoomed back in. As an engineer, I look at the difference in viscocity at (in your case, 125°C) and say "they're all the same number". Even though those lines are not completely collapsed down onto each other, the oil grades you are talking about (40, 50 and 60) are teh top three lines (150, 220 and 320) and as far as I am concerned, there is not enough difference between them at that temperature to be meaningful. The viscosity of 60 at 125°C is teh same as 40 at 100°C. You should not operate it under high load at high temperature. That is purely because the only way they can achieve their emissions numbers is with thin-arse oil in it, so they have to tell you to put thin oil in it for the street. They know that no-one can drive the car & engine hard enough on the street to reach the operating regime that demands the actual correct oil that the engine needs on the track. And so they tell you to put that oil in for the track. Find a way to get more air into it, or, more likely, out of it. Or add a water spray for when it's hot. Or something.   As to the leak --- a small leak that cannot cause near catastrophic volume loss in a few seconds cannot cause a low pressure condition in the engine. If the leak is large enough to drop oil pressure, then you will only get one or two shots at it before the sump is drained.

      Help! Leak coming under transmission

      By GTSBoy · Posted

      So..... it's going to be a heater hose or other coolant hose at the rear of the head/plenum. Or it's going to be one of the welch plugs on the back of the motor, which is a motor out thing to fix.

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!
