Aftermarket ECU's can be engineered in NSW (at least, dont know for other states) provided the engineer is approved to certify ECU changes - which most are not.

same over here, follow the regulations, take it to the right people & pay enough money!

Edited by WMDC35

Technically, where aftermarket ECUs can be engineered, the vehicle has to pass a rather expensive emissions test and the ECU has to be locked afterwards. The only time it's really feasible is when you are doing type application for a limited run production of something or other (like the modified 200SXs that some crowd was doing years and years ago, or clubmans, or that sort of thing) where a number of vehicles will all be the same and can amortise the cost.

Which state are you in?

Yeah it's fairly simple. Too bad there's so many tightasses buying Skylines thesedays who dont think engineering is money well spent.

An engineering report here for example is generally about the same cost as a Garrett turbo and includes all mods to the car inc emissions and aftermarket ECU's.

Emissions test is free.

Locking the ECU is free.

Engineering report including all the mods to the car (increased wheel size, change of turbo, larger FMIC etc) will set someone back about $1200 from a certain Sydney workshop.

IM240 pass is required for engineering certificates.

Totally free.

Had one done last week.

How did you go with getting an electronic boost controller engineered ? As far as I know from the various phone calls I made no one could guarantee a valid engineering certificate for this. Who did you use to get your vehicle engineered btw ?? PM me if you dont want to discuss in thread. Cheers :)

Wow. I have had my car for 13 years and for 12 of those it has had a hole cut in the inner guard for the intercooler. It has been for countless road worthiness certificates in NSW and also passed in Vic. I have had two accidents with two different insurers and one of them required replacement of the exhaust and intercooler...no voiding of insurance.

If you can get cooler piping sorted for a reasonable price then go for it. The problem with GTR coolers is that they work out far more expensive then all the kits getting around which include piping for connecting it; all well under the cost of custom piping to make the GTR cooler work

That's because roadworthhy inspection mechanics are more often marginally competent or simply don't care about things like that. Certainly more so than the complete safety nazi types who would quickly earn themselves a reputation and therefore do themselves out of work/business.

If you had a frontal collision in which someone died in your car, and there was some way the insurer could claim that your interference with the crumple zones of the car contributed to the death, you'd be up shit's creek. And it's not just your comprehensive insurer you have to worry about. 3rd party bodily insurers are the same as any other - they will look for ways to get out from under a claim, and you don't want to be stuck with the results of that.

I too have had my car for 13 years. And for 12 of those it has had a hole cut in the inner guard in front of the airbox. Looks stock. Not like the dodgy hole in the chassis rail most Skylines cop for the cooler pipework. After 13 years of ownership my car has to go in for an inspection at Regency for the recent engine transplant, so that it can remain legal. Before I do so, I have to straighten out some dents in the chassis rails under the floorpan at the back of the engine bay. Reason? Because dented chassis rails will result in a defect when presenting to Regency. I was under an R34 GTR a few weeks ago that will either need about $3000 of work to fix up the dented rails and sills, or be wrecked.... because it has a defect sticker on the window and it won't be passed at Regency. Nothing else wrong with it (apart from the loud exhaust that caused the defect). We may get it easier in terms of regular inspections here in SA. But the rules are rather rigidly enforced when they are enforced, and there is no dodgy swede culture for getting defects cleared like the Eastern states have had for most of the last 10 years.

can i do a reverse flow on my gtr intercooler? ill just make up some piping to go underneath an back to the standard holes that will work wont it? an does it matter if the intercooler is 3'' inlets an the piping im using is 2'5'' so ill just us rubber addaptors will that make it lose power?

Brisby you so rarely drive your car on the street it's never an issue. I bet I've done more KM's in my SS in the last 2 months than you have in your 32 in the last 6 years!

To the other comments about cutting/non standard holes & un-insured - Not quite correct.

The only time it is an issue is on models that have airbags from the factory. Non-airbag models and cutting holes is perfectly fine and legal. Some states you don't even need to get an engineers. Also that said an engineer won't have any drama signing it off either way if its done right, I went through this with my GTS-R and putting a RB26 into it, it was basically a non-issue for the engineer from their point of view and the hole was about the dimension of a big tissue box :)

Also most Police won't defect you either because they know it's only an Airbag model related issue (In Vic at least, and we have it the worst down here).

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
