A RB30DET was a motor never offered by Nissan, it is illegal until tested... The test costs 3k, and if you fail that's it.

So clearly it will never be legal either :blink:

I don't know that the cylinder head effects the eligibility of it for compliance. The block is made by Nissan and all factory mounting positions are maintained. The do the same with V8's....HQ 308's never came with alloy heads but if you put one of those engines into a different car, they are still able to be certified regardless of cylinder head.

Honda is another example with the KA20? with 24 cylinder head or something. Pretty sure it's cylinder block related

Apparently changing heads from single cam to twin hurts the environment according to Victoria EPA.

In eyes of EPA in Victoria, twin cam RB30 doesn't exist thus the need for emission testing.

surly you wouldn't just roll up and ask for a cert? You would do some home work at least right?? There's always loop holes.

If you were to do something along those lines your be finding an engineer and Maybe for argument sake paying a few hundred extra to find out what can and can't be done and working with them.

It carnt be impossable you just have to make it save and pass the tests ect and if your wallets deep enough and you want an rb30 in your r33 then I'm sure it can be done!!

Personally I can think of much better things to spend to money on but hay ho

The reason no one bothered is as Ash pointed out the emission testing cost $3k, if you fail thats it.

If you want legally to have RB30DET, move to another state.

Well not really.

You have to basically go through the entire ADR emissions testing for Vic. It's not like NSW where you can just get a quick test and off you go (where you can get it pre-tested).

The equipment is not cheap, so for a "pre test" you'd probably be looking at close to the 3k anyway.

Its quite involved and it's not just 5mins on a dyno. It's the full testing in closed conditions for 20mins, road testing and whatever else goes on as part of ADR certifications for emissions standards...

Basically forget it in Vic for 100% legal is the theme here.

Dan - Ye to an extent, but they class it as 3ltr and SOHC falling into one emissions setpoint as a factory motor.

The motor you are making is not a factory offering, therefore there is no emissions data available to reference off. If Nissan made a RB30DET - you'd be sweet :rofl2:

Stuff all that crap. I'll just buff out his engine No. and stamp in my currently engine Number. Thanks guys.

X stamp the hell out of the old number first, then put new number on top. If they get that thing under X ray you'll be in more trouble than just a defect...numbers go right through the metal past what the eyes can see :)

What do you think it would cost to make up a spacer plate , fit it to the block and bore the "sandwich" for thin walled liners ? Paint the block keep your number and claim the 5th if questioned .

In with the 30 crank/rods/pistons and have a real torquey "RB25DET" .

Don't they all roll off the boat looking like that ?

      GCG is a good company, they're a major distributor for Garrett in Japan as well.

      Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣

      I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).

      Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂

      Why am I hitting a power wall with my stroked RB25?

      By GTSBoy · Posted

      You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
