Do I Have A 24u Block?

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.

      Yeah, you are right. It seems easier and more reasonable to boost the engine. And as you said the blocks are very similar but the cylinder bores are different.

      Anyone know this frontpipe?

      Sound logic, but in actuality way more illegal than just having the wrong pipe. Normally, doing something like that would be forgery. Meaning you may have certain documentation for vehicle parts, but the actual parts are different ones and you just assign them the numbers and badging from the documents. But nevermind that. Nonetheless, I AM curious if this pipe was ever made by any official manufacturer this way, because I honestly am not familiar with this pipe layout and shape. As I will be putting on the HKS Silent Hi Power once my exhaust gaskets arrive, as long as it sounds right I will just roll with this front pipe. I can always order the actual Mines part if I run into legal issues. It would be an unnecessary expense as there is lots of other problems I have on this car as of now.

      So, weld a plate with the Mines logo laser cut into it, onto it. Instant Mines pipes, whether they were or weren't originally.

      I don't know if the blocks are "the same". They will be very very similar. Obviously, either the bore or the stroke is going to be bigger on the 20. If the bore is bigger, then the 18 head is unlikely to fit properly. If the bore is the same, then you can almost certainly fit the CA18 head, but there migth be a few fun things you have to do to make water galleries (or other things) line up properly. Or... it could just be real easy. Is it worth the effort? Almost certainly not. You can make nearly as much power on a 2 valv ehead as you can on a 4 valve. There's not any "magic" in a 4 valve head.
