Difference between JDM and USDM versions
i'm new here and i own a JDM 250GT
to the best of my knowledge everything should be the same except for the litre size of the engine
does anyone know other differences? do all parts (performance/ exterior) that are made for the G35 sedan in US fit the JDM 2.5L model?

mine is a 2004 model and it's the same as the first gen G in US
i will take a picture of my engine bay this weekend and post it up
from what i can tell the layout is exactly the same as the 3.5L and it would be great to know if i can use any of the intakes for my 2.5
i'm looking to put on the Z tube and JWT pop charger

It's not a 4, it's a VQ25DD six, same as the VQ35 but smaller bore/stroke. It has direct injection as well, unlike the 35 from what I know. Here's a pic of mine:
I think most of the external engine parts will fit. I've bought a radiator off the US market for mine so far. Things like the supercharger and turbo kits won't fit because of the engine capacity (too much boost & fuel) and injectors might not fit either.
I also bought a USDM battery cover (the JDM battery is on the left side) and it needed modification to fit. I need to take a new pic of the bay to show it. Planning to get a new CF engine cover sometime. Also bought a JDM battery cover off the US market - fit like a charm.
If you look at the bottom right of the pic, the JDM 250GT has a cover on the air filter box where the G35 has a little snorkel. I pulled my cover off and the car sounds a lot better

Looks like the intake would work. Can you take a picture with the engine cover off too? I think there is a chance the plenum spacer may fit as well.
As for the SC/Turbo kits, I bet you could use them as long as you got a re-tune. I'm not sure the plug and play engine management would be the same since your ECU may be different but something like the emanage ultimate should work.

Sorry, I didn't realize I had put DE in my first post, it should have been DD. Must be a holdover from my R32 days (RB20DET, no DD's back then). I'll edit. My engine cover says "Neo-Di" on it, Di for direct injection.
Here's a page from the Nissan parts system showing the 25DD plenum parts.
