Anyone Registered/engineered An Rb30det?

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

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

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.

You could get the engine re stamped as an RB25 or 26 depending on the head you used. This would make it easier to engineer because you cant have an older engine in your car then what it came with origionally.

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

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.

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

[Cubes]

It still has to be engineered, there's no if's no buts.
