the only difference on the 2007 spec v is the intake manifold i believe is bigger and the ratio changed also which allows the extra 30 hp onto the engine but yea imma see if it fits then ill let u guys knw. ill still accept any help so if anyone else wants to help me out please post

Eh, the 02-06 SE-R 2.5 and the 07+ one have several differences. From what I can tell, Altimas continued to use the old QR25DE instead of switching to the QR25HR in 07 like the SE-R.

Thus, between all 4cyl Altimas and 02-06 Sentra, the QR's only differences are ECU tuning and (supposedly) intake design. All parts are cross-compatible except possibly a CAI/any other external intake mod, since the engine bays are different.

Intake mani is the same (at least in terms of fitment - i.e. an OEM or aftermarket SE-R one would bolt right up, though they're probably the exact same to begin with), I meant that everything before it (intake piping, airbox) is different.

You mention intake manifold, then turbo manifold... you don't need an aftermarket intake mani to go turbo, and actually I don't think there even is one. Most turbo setups come with the exhaust mani you'll need.

Which is an exhaust manifold, which should come up with your turbo kit. It will also be the same as an SE-R's.

Piecing together a kit is tough. You're going to need a whole turbo-back exhaust, intercooler piping + BOV/BPV, fuel pump, and fuel pressure regulator as well.

Now that I've realized that you're piecing together a kit, I get why you're asking about the mani specifically. Take a look at Protech manifolds (Google that phrase). I think they have a QR one. If not, SSAutochrome might have one, but the Protech would definitely be the better buy, IMO.
