^^^ 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.

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By BaronOBeefdip · Posted

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to it's full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so damn hot in there, that made it all the more easy to remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. I was standing there looking at the car and said 'f**k it'. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.

      Thanks for that, hadn’t used my brain enough to think about that.

      R33 GTR running -9 with no tune

      Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.

      You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
