I remember reading somewhere that the 2.5 L is the same 4 cyl. engine that is in the Altima. I would therefore assume that all engine mods for the 2.5 Altima would also fit our engine. My question is......anybody know if cam gears and pullys are available for the Altima 2.5 that just isn't showing up for the Spec V? I've just starting researching this but maybe someone has already done this and either came up empty-handed or has some goodies. What's the word?

While the Altima and SE-R share the same motor, they do not share the same ECU (to my knowledge). This means that perfomance mods will fit both cars, but the computer will react diffrent to each mod. Also the drivetrain is diffrent so mods like CAI's and Exhausts will not be the same. Mods like Pullys should work on both cars, cams would be a diffrent story again because of the ECU and the way the computer adjusts the power in the SE-R vs. Altima. The exact details and diffrences are unkown becasue there are very few parts out there so far. Also people looking for performance out of the Altima bought the very powerful 245hp V6 trim.
I doubt that the Altima ECU is better, I don't know for sure that either one of them are "better" they just have diffrent applications. I'm not sure what the stock HP on the Altima is??? that would be a good place to start. I do know that becase of the Tranny diffrence the ECU is diffrent, and NOT interchangable.

timing is why you would need higher octaine gas. I can't see the altima having the same HP running 87 octaine... it would face even harsher retarding of the timing than the spec v already has with 93...

got it... at first i was like WTF is he going on about then i was like, well i respect his knowledge, so i asked 1/2 thinking it was a joke and 1/2 thinking you had info i did'nt have.

nissan claims it is due to the exhaust thats rather restrictive actually. but its more than likely a more agressive computer map, thus the reason for higher octane fuel. to counter things like detonation, and to run smoothly on a slightly dierent timing map and fuel curve. cause i looked at the exhaust on a spec V and my SE-R and its the same.
and stickers dont forget the stickers... EVERYONE knows that stickers make a car go faster, even is the parts those stickers are for are not in your car it still works.. so save money just plaster yer car with stickers it will go supa fast then
I think that possibly the ecu's for the 2.5 Altima and the Sentra Se-r 5-speed could be the same. Who knows, maybe the 5-speed in the Altima and Se-r are the same trans.
hey Red, I put pedal covers on my car, and you should see the performance increase!!! I havn't put any stickers on it yet, but I am still getting used to the added perf. from the pedals!
those pedals should shave at least 2 tenths off yer time just think when you get all the stickers on it
