Hey,

Recently had the car nistuned. Z32 Computer etc.

Car is now running 200Kw atw safely with no ping and good afrs. Required around 14+ psi on stock turbo. Yes im aware of the risks involved. In the past with a remap it ran the same with 12psi but developed some pretty bad detonation. Too much timing apparently and this had to be retarded considerably to achieve similar output without ping (is was being tuned on a hot day too, bout 30 degrees +) But the boost required to achieve 200 ATW seemed a bit excessive considering what others have posted...This engine seems to really dislike advancing the timing...

Ill be highflowing the standard turbo very soon the question is..... running the SAME pressure (say 14 to 15psi) with a highflowed turbo as opposed to the stocker, should i be expecting any sort Kw gain?? or it simply just assuring no turbine failure?

Looking for 250Kw ultimately. and i cant see how an extra 3 or 4 psi is gonna achieve that

85k on the clock.

So altering/hi-flowing the turbo and no tune?

Who knows, could be a dead motor.

As for once you have a tune - how much power is made, purely relies on the hiflow itself, what wheel combination is chosen and so on

hiflowing the turbo and having it tuned to suit.

dead motor. how so?

yes, kw gain. the highflow should be moving more air. ie. more power (with suitable tune etc etc etc)

also consider injectors. its asking a lot of the stockers at 250kw, if they get there at all.

what are the stock injectors good for usually?

Gave her a bootfull a couple of times on the way home. EBC shows peak of 14.7! dyno showed this spike, and then drop off to around 13 which it holds. Pretty much wheelspin from 5k in 1st. But 3 attempts at that and the clutch feels pretty soft...

if the timing and injection values were set correctly on other load points by a good tuner and if the car was treated to a new turbo, then chances of it blowing up is quite minimal, no need to dramatise :blink:

most tuners just focus on the map trace and ignore other cells, hence sometimes you get ridiculous knock going up a hill or down shifting.

if a tuner smooths out the ignition and injection settings for everycell on the map, then there is no need to worry for such a mild motor.

For example with the stock turbo you're only hitting rows 16, and with the aftermarket one you're hitting rows 17 on the load map, and if only rows 16 and prior were tuned, then you'll have a problem.

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
