Looking at building a new engine for my Stagea. Due to its kerb weight of approx 1750kg's the Rb30/25 sounds like a good option.

I live ine Queensland and get it approved, but do not want to limit a future of the car one day to just Qld buyers

It is a 8/98 model car, but rb30 block will be an 1986-88 model. It is also AWD so a bit more work is needed compared to going Rb26 which was a factory option in the 260RS, so it can or will be legal in all states.

I have already bought half the rebuild parts need for Rb30, but could always resell them and buy another rb26

Not concerned about costs in swapping everything over from what I currently have

Opinions wanted

the engine cant be older than the car, however as it covers in the thread ash linked all the emissions relevant gear is part of the head/external to the engine itself. so as long as the head is not of an older series than that which came with the car its ok in that respect.

As said above the emissions must meet with what ever is newest, in your case the car.

If you were to put a NEO 25 into a 240Z the emissions are based on the motor because it is the newer of the 2.

The rules are a lot more relaxed in qld than they are in the southern states from what I understand. You wouldnt believe what you can do up here if you have a good engineer on side.

All this talk ive heard about the inter state rules being all bought into line will change things. Weather its for the worse or better who can say. They cant revoke cars that are already approved in QLD, but they can certainly stop new cars from being re-engined.

They did that a few years ago with VW's and the old Myers Manx rebody conversions. It used to be classed as a re-bodied 1968 vehicle which meant it just had to meet the emissions of that era. Now to do the same conversion its done under ICV rules, so you have to somehow get a 1940's designed engine to pass emissions. In a sense its the governments way of 1. preventing vehicle modifications, and 2. getting old vehicles off the road.

May sound like a little extra work but, Pull you standard engine out, clean it and wrap it up in your garage somewhere, put your sexy 3.0 litre in and then when the time comes, you can drop the orginal engine you have stowed safely away back in.

Forgive me if I've misunderstood your post but if you're suggesting that the stocker be installed for compliance purposes and the 30 be installed for driving duties, as stated in the linked thread:

When you crash and kill someone let us know how the arse raping goes.

Wrong, just WRONG.

An older engine CAN go into a newer car, BUT you must bring emmision standards up to the of the car.

Read the regulations, they clearly state it can be done, but there is an advisory to use a new motor in an old car as the emmisions will just have to meet the motor...

The engine is one factor too. How do the engineers feel about spacers under the cross member to lower the RB30's so they actually fit the cars? Because technically it does interfere with steering and suspension geometry at little...

I think you did misunderstand it a bit mate as he isn't complying his car, he already owns it from what I can interpret from his original post.

What I was trying to say and perhaps was a little shady on, is that his goal is to retain a buyer market including people from all the states of Australia.

Therefore, he may remove the standard engine, perform the swap to RB30 (which is legal in Queensland, as he has stated) and simply store the original engine to be re swapped back into his vehicle, when and if he choose to sell it, thus making it eligible for sale in all other states.

RB30 swaps.... No soap dropping, No homo :devil:

When I wrote compliance I wasn't referring to complying the car I was referring to complying with the law re RB30s and rego etc. Confusing choice of words on my behalf. Also thought you were replying to Zebra not Darrin. Thanks for clarifying I see your point now.

      RB25DE NEO with Haltech ECU

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
