Anyone registered/engineered an RB30DET?

is it a legal or illegal conversion to put an RB30 block with a RB26/25 head into an R32 GTS-T which came out with the RB20DET?

Last thing i want to do is do the conversion the get defected and have to fork out shit loads.

Anyone have friends who go the "original new block from nissan with BYO block number" route? ;)

Thanks for your time,

its illegal

you cant get it engineered unless you go through the whole ADR Emissions testing.

The motor was never brought out that way and hasnt been tested.

In saying that, if your a resourceful person im sure you can find out ways to get around it ;)

I've been told that one is required to run it on the stock ecu.

Run the larger R33 GTST or R32 GTR brakes.

Motor Reg didn't seem to worried about it as they said there would be bugger all in it as essentially its the same motor simply stroked out a little.

You would no doubt need an engineer though.

How will they be able to tell just by looking at it?? Couldn't you just pass it off as a rb25 or 26??

all a cop/road auth has to do is look at the engine number... try passing it off then and you'll find it will go downhill very quickly :P

I dunno about running it off the stock ECU however. If you cant run a bigger turbo, you cant run a bigger capacity motor.

Emissions would be changed without a doubt, thus altering the compliance

Why does the engine number matter? Mine isnt recorded anywhere on my rego papers, and it hasn't got a stolen motor in it. It is the asme as if you bought a new block off nissan, then stamped your old number on it.

cubes ran his off the stock rb20 ecu for a while there.....

My engine number is on the rego papers.

Yes, I used the stock ecu for the first ~10,000km's for the run-in. AFR's were perfect and fuel economy was the same as the rb20det.

It was fuel cutting on anything over ~7psi or there abouts at around 2500rpm. Nothing an ecu remap couldn't fix. :D

The R33 ECU works perfectly fine. In the early stages of the r33 rb30det thread one of the blokes made ~200rwkw on the stock ecu. No power dips ran quite good. But it did need a bit more cas ignition timing as the rb30det comp was 8.2:1 where as the rb25det ecu was setup for 9:1.

ECU - as in terms of it being legal. thats the topic... not how the car runs, they beside the point when dealing in ADR requirements.

Just cause its a stock ECU means nothing. Its not a stock motor

Remember the 3ltr block has a different sequence to a 2.5ltr one.

what did they use on your rego then when they took down all the details?

I dunno how SA works but you wont get away with that shit here.

Thats about it. I could get it legal here, then drive across the boarder and get pinned for it. As the boarder is all of about 50mins away, its not that difficult.

That said everything is legal, just depends on how much money you got on hand to bribe the cop that pulled you over :D

    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option 
    • You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
