^^^ that good to hear mate, that u passed the test not that u got done by EPA. Gives me hope that I'll pass too. I have a stock exhaust so hopefully the cat will be good enough to cut emissions and quiet enough as well. Btw what kinda power u get with Racepace tune. I was about to take mine there but got he EPA notice before I could.

Factory GTR exhaust cat-back, with aftermarket dump/front pipes won't generally pass.

To the other guys - I class Nistune as non-factory.

As soon as you alter something from OEM, it is no longer classed as "factory" far as i am concerned.

And they will take the cover off your factory ecu to check for extra chippies - kents snapped a screw on mine and left it like that when it was being used for another car through EPA.

They will really open up your ECU? I have never heard of this being done before, I would argue that they could damage something with static and that I would refuse to let them dismantle something in my car, unless there is obvious stickers all over the ECU saying it has been chipped/has a nistune module in it then I can't see why they would want to open it up.

Yeah, as below, with NIstune it appears (visually) as though it is, infact, a stock ECU. Except you'd have an AM AFM. Which can be explained in no other fashion other than something illegal being changed. I guess that depends entirely on whether NISTune gets by Victoria's EPA people.

Cause if you had highflow turbo(s), NISTune, highflow injectors (or appropriately coloured ones) the only visually defectable or 'wrong' item would be AFM's.. which, on their own, arent specifically excluded.

Probably a discussion for the VIC EPA thread though..

I have sent about 15 cars through EPA with nistunes and all passed with flying colours, cars ranged from 230kw to 400kw.

A sticker change on a AFM goes a long way to conceal its changed on a RB25 as its the same size, GTR's are a non issue as i use NISMO items and they look factory too.

Injectors must be painted and its easily done with the correct plastic model paint, will even handle jet wash and steam cleaning.

If the car looks modified then yes they will start to investigate, best bet is to do everything in wrinkle black and covertly then they wont even bother looking.

hi mate, i passed an epa full emission test with a standard airbox, hks front mount, hks 2535 turbo, big fuel pump, dump pipes and front pipes with a tiny exhaust from the cat back and power fc on my r33 gts t, no worries, all i done was rub of the hks print on the wastegate and remove the power fc hand controller. easy job

Does anyone know if you must have the standard boost solenoid hooked up or is it fine to run it off the actuators? My point being, my car doesn't have the standard solenoid, I was just going to use a T-piece where the Aftermarket boost controller is.

Read the EPA thread dude... It's all in there.

The EPA do know about factory solenoids, and ensure they are connected. All emission controls must be connected.

Sometimes you are lucky and get away without it being checked.

    • 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.
