I think so. I doubt the Nismo exhaust alone is producing 18hp, and if I'm not mistaken, the Nismo intake is like dual pop-chargers, which put out about 6hp if they're similar to JWT's. Put the two together and you probably get your 18hp gain.

Ricer Math here so i am sorry but 332 flywheel plus 17rwhp = 349. I know you cant add flywheel plus rwhp but it was easyer to do that then figure out its flywheel HP.
Do you even need to add direct injection to get that number? from what i have seen no you dont.
I predect they unviel semtex car heheh.

The average flywheel to wheel hp loss is 17%, so if you figure 17whp as being 83% of flywheel, 17whp works out to 20.48 hp at the flywheel. Add that to 332 and you get 352 hp.

The theory I was adhering to earlier was that they did this to lower the HP specs on the 370 to make the GT-R look better in terms of $$/performance. Now I'm thinking more like they did it to make the NISMO edition look better.
