Hey all,

Took the seats out of my R33 GTR Vspec the other day (long story) and on the removable plate (where you can get access to the ecu etc) it has 24U stamped on it.

I knew it meant something to do with the engine number however for some reason I though that 05U was associated with the N1 block, which is obviously incorrect.

So, I have 24U stamped on the access panel behind my rear seats... should I get my hopes up? Where should I poke around under the bonnet with a torch to check?

Cheers,

Big Mike

check the engine numbers with nissan fast software...

u sure its not 24V (although car batteries are only 12V)?

Definately 24U on the plate.

Ok, thats gone over my head, how do I access to this "nissan fast software"?

Thanks,

Big Mike

You cant check engine numbers that came with a car from factory with FAST as far as im aware.

Mike you need to look on the exhaust (turbo side) of your motor, on the block. Its stamped on there. You wont be able to see it very easily from the top especially with standard turbos.

Also mate that box behind the rear seats isnt the ECU, that would probably be your HICAS/ATTESA controler. ECU is in the passenger side kick panel

Awesome, cheers mate. Yeah I got pretty much stock everything, so might have to dismantle some of intake pipes to the turbos and get in and have a peek with a torch.

Learning stuff all the time on this car thats for sure.

Thanks for your help thus far!

24u just means n1 parts not the actual engine itself, i have a n1 brake booster and its got 24u on it, and same with other parts too, so 05u means normal gtr parts and 24u is n1, so im thinking n1 attessa ecu or soemthing has been put in the car in the past as a replacement for the dead stock one?

That makes sense also. This weekend will have to have a bit of a snoop and find out what the story is anyway.

Thanks for all the help so far guys, will post any updates.

    • Thanks for your insight, it being basically useless will impact my decision for sure. I thought it may help the engine breath better I guess. But then again, I have also been told that tuning an RB20DE is also not worth it. Exactly, we follow EU Regulations. There is a bit more leeway on older vehicles. My Porsche 924 came without a cat from factory and managed to pass, they still mentioned that I have quite high emissions on it though.
    • My apologies, I stand corrected. Thanks for registering to mention this! And thank you for actually reaching out to the council to clarify. This is the sensible thing to do and the opposite of what I was alluding you were doing. I may have seen too much outrage and hate being fueled on the internet and it has made me a somewhat cynical old man. Sometimes it is easy to forget that there are real people behind websites and accounts. In my defence, CarExpert and CarExplore do read quite similarly at a glance. I shall try and do better in the future. (Please stick around to get the latest scoops on dealing with old Nissan shitboxes )
    • Don't bother. The poor little RB20 doesn't make enough gas flow to challenge the flow capabilities of even the littlest cat, and you won't make any extra power, and all you'll do it soot up your rear bumper. Plus....is Malta not runing under Euro regs?
    • Hey Daniel, sorry to hear that and thanks for posting up for us at a really hard time I only knew SmoothLine through the forums, we never met as we are based in different states, but when he was most active on here he was quite a while back so not many of the current crowd might remember him. I am pretty sure he was active in the Queensland SQU club but that is defunct now too (times are changing and we are all getting older). Farewell SmoothLine!    
    • Turns out depending on whether the car was equipped with TCS or not there are different signals coming to the dash, meaning there are different speedo clusters.  Wired in a speedo calibrator box from aliexpress and now works fine.
