[el_blacky06]

I KNW DIS AINT MY FORUM BUT SINCE I GOT THE SAME SIZE ENGINE FROM THE SPEC V I NEED HELP GOING TURBO. I WANTED TO KNW IF AFTRERMARKET INJECTORS AND THE TURBO MANIFOLD FROM THE SENTRA SER SPECV R THE SAME SIZE AND BOLTINGS FOR MY CAR. THANX FOR UR INTUPS AND I HOPE I GET AS MUCH HELP AS POSSIBLE FOR MY ALTIMA TURBO BUILD

Same engine, same parts.

[el_blacky06]

i waz told itz same parts in the past but i dnt want to jump to conclusion and end up buying parts like lets say upgraded cams and they dnt even fit on my car

[aebstract]

The 2.5 altimas are the same exact engine? Hmm..

[el_blacky06]

from my knowledge i knw the spec v engines r way stronger than my engine internally and headers from a sentra do fit on my car just dat the downpipe goes a bit to the side datz it. i want to get an intake manifold but idk if it will work the same way

[aebstract]

Oh, well s***.. I didn't know I was running harder than altimas o.O That's cool to know. If you do, let me know if it fits.

[el_blacky06]

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.

[el_blacky06]

ohh yea i knew all the above except about the intake design i thought it waz the same from the 2002-2006 spec v. well i guess imma have to go custom on the intake manifold and i just received my apexi safc controller = ] is anyone eselling a turbo manifold from a 2002-2006 specv?

[nametakennow]

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.

[el_blacky06]

ohh i knew about the top portion but i didnt knw about the second portion. well as long as the turbo manifold fits datz all im concerned about at the moment. thanc alot! now does anyone have an aftermarket turbo manifold for sale? from a spec v 2002-2006?

[nametakennow]

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.

[el_blacky06]

yea one of my friends had told me the same thing about the intake manifold dat theres no need for me to switch it. but i still need a turbo manifold

[nametakennow]

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

[el_blacky06]

kool thanx alot for ur help so far i got the intercooler, apexi safc, turbonetics t3t4 turbo, but i still need the injectos and the exhaust manifold

[nametakennow]

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.

u should bring this up in the altima section......theres one guy qr25 or w/e his sn is who is building a turbo as we speak plus u have blake and others who have had the turbo that could prob help out.

post up in the drivetrain or a/c section

[el_blacky06]

my friend from socal evo hooked it up with a blow off valve for 40 bucks its a greddy brand and phenom78 ill bring it up to the altima forum as soon as im ready to install the turbo kit so that way they wont be waiting for updates from day to day like scott is
