so got new piping and a bunch of other stuff done, tuned, driveable etc. Took it for a punt around in late December. low 20 degrees at dusk, check intake temps while taking it easy driving home: 45-50 degree intake temp.Thought that was a bit high, spoke to some people and they said check the intercooler.

Bosch style plastic temp sensor fitted just before the plenum. metal weld-on bung, all stainless piping.

2.5" piping, intercooler is 600x300x80, 3" inlet and outlet. Apparently its a PWR core "custom" made at Race Radiators in dandenong. Was spray painted black very roughly by me. Intercooler sits in front of a small oil cooler, and a custom radiator behind the oil cooler. Intercool is approx 12+ years old, few squashed fins but mostly in good nick.

1) do these intake temps seem acceptable for a small car cruising around at 80km/h?

2) does this intercooler seem quality? worth replacing for something $$$?

I cant think of an easy way to test intake temps before or after cooler for comparison. Need to get another temp sensor, wiring, weld-on bung etc.

Agree with kiwi. I'd be verifying that what the sensor says is correct. I've got a shitty return flow blitz in my r33 and the intake temps while cruising around are only a few degrees above ambient. Does heat up a bit at standstill but recovers quick when driving off again. My temp probe is in the j pipe around 20cm prior to throttle body.

 

Does the pipe get hot to the touch?

    • 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.
