What can WE do

[AlexM.]

I dont necessarily have to have headers for the BD Tuner would I? All i have is an intake and full exhaust.

Nah, you don't need anything for the BDT. Actually if either of you is interested, Ranga14 might be selling his. I know he was selling it a while back but I don't think anyone bought it

[XenonSE-R]

For a 2.5 - a catless header is your best bolt on power adder. This is basically the equivalent to the Y-pipe in the 3.5 as far as "bang for the buck" bolt on performance. The Bully Dog Tuner can then be used to tune your ECU to optimize the performance gain found in any bolt ons you add. You will likely sacrifice some fuel economy in return using the Tuner, however. On the other hand, the BDT gives you the option to return to stock in the event you want to sip less gas.

How is 91 octane bad?? My car seems to run more quite. I do know that sometimes cars "don't like it" when you go from running higher octane for a while, and then switching back to lower octane.

knock sensors

timing

detonation due to octane level

s*** like that.

also the part about how theres no real gain and wasting the extra couple bucks on something you dont even need..... the "quietness, smoothness, added performance" most of it is in your head...

Bottom line, end of story, especially in Nissan engines, it is better to run higher octane gas. It will NOT hurt your engine - it is better for it. There is a reason Nissan recommends it. I ran 93 octane in my Sentra Spec V (the same 2.5 used in the Altima Coupe 2.5) and I didn't run into any of the problems that were common in that car (precat deterioration due to post-detonation issues inside the precat area, leading to pieces of ceramic being sucked back into the engine and causing the engine to fail).

High octane gas will not give you a horsepower gain. It will give you an efficiency and a LONGEVITY gain for your engine. Keep it running smoother, longer, with less wear and tear on internal components. Not saying you HAVE to run premium fuel (unless you have a requirement in your vehicle, and the older 3.5s DO require premium), but it is never a bad idea to run it. You will eventually make up the extra cost in the long run saving on potential engine repairs further down the road - your vehicle will operate more efficiently and therefore last longer as long as all your maintenance practices are proper and in place consistently.

You may see more rewarding gains in suspension rather than power.

The 2.5 has a 61/39 weight distribution, so it's not quite as terrible as most FWD.

They also weigh only 3.1 thousand lbs.

Therefore it can be a very fun and nimble car with a few suspension bits, and maybe some weight savings. Rear sway bar, front strut bar, and springs/coilovers will make the car handle very well, like a completely different machine.

That might a be a more effective and rewarding route than trying to squeeze 30 extra HP out of a slow engine. Even if you manage 200hp at the wheels, it won't be fast enough compared to other cars designed for straight line speed.

Right here. If you're gonna go through all this trouble just to beat hondas and other $5000 or lower cars, its not worth it. Those cars, as much as I hate em, actually can hold their own since 1) there engines are designed completely different than ours 2) alot more performance mods that ours and 3) like someone said, our cars (2.5) are not designed for racing.

With that said, these cars may be able to hold up well to a civic with basic mods like intake/exhaust. Then again, I never raced a honda with this car because i didn't buy it for speed. I could've gotten a G35 if I wanted to, but I preferred this car due to having previous experience with a Nissan and its reliability and I wanted something new and not used and the looks were close to a G35.

[Mr. Dexter]

Well we do always have looks on those nasty Hondas the only other car I'd buy right now (if money permits it) would be the Hyundai Genesis 3.8 R-spec. Throw a twin turbo on it and it becomes a f**king monster! Can't wait till I'm a bit older and have the capability of making a decent amount of money.

[XenonSE-R]

It will come man. Trust me - I had a 97 cavalier sedan for my first car. You're off to a good start. lol

[SanoSuKe]

lol bro you're good, 16 and driving an A/C. When I was 16 I was driving a stick shift PT Cruiser

[Innovazn]

First car 91 Accord (age 17), Second 92 Corolla (age 18), third 02 Stick Civic Coupe (age 18), fourth 06 Magnum SXT(age 18), fifth 02 Pathfinder (my precious)(age 20), sixth 12 3.5 A/C (new baby)(age 23)

[mikethemike]

3000gt SL for me when i was 17

[AlexN09]

Saturn l300 v6 sedan from 16 to 20. Blew the pants off my coupe lol now I've had this for a year and it still makes me cry when I press on the gas. Slowest car I've ever driven honestly

Nothing was worse than my slow 3000gt aka Sherman Tank. I do wish this altima had the same engine with less restrictions as my 2004 Altima. The only thing I liked better about that car than this is that its acceleration was quick and you gotta realize, or Nissan should realize for that matter, acceleration is actually very important to have on a car. If you're about to get t-boned by a car, for instance, you're gonna want to get out of the way quick! Screw trying to save gas! But I suppose thats where BD Tuner comes in, unfortunately.

[J Russ]

First, 2007 Honda Fit (16), now I got my baby...got her when I was 17

[Mr. Dexter]

Plan on buying a 2010-11 Genesis when I can. Dont get me wrong, I love our cars but the 2.5 is just too wimpy for me. And the 3.8 of the Genesis is just calling my name.
And J Russ very clean looking A/C

[YoungCoupe]

16 here too, rocking my 2011 AC

[MuranoDriver]

It's cool that you're 16 and don't sound like an idiot. BDT is probably your best bang for the buck.

Thank you Alex. I figure I'll get the BDT first and then get more performance parts so I can have a baseline to work with and know how different parts affect it. The next step would probably be an exhaust and then from there I'd probably do the ZEX safe shot since its +35hp which is way more than headers, intake or anything else will bring to the party.

The parts in bold will give you the HP gains at all times. The NOS is only for 10 seconds... maybe?

I wanna play!

1st car- 1994 Honda Accord (Have pictures ) dented front bumper, hood,grill. Bald tires, bad breaks, interior looked like Freddy went through it. Oil constantly leaking, coolant leaked as well. Falling apart to sum it up.

2008 Altima coupe 3.5se- Best freakin car I've ever had hands F*ckin down!!!!!!!!

Well out of all the cars you owned half of them where junk, so of course THIS ones gonna be the better car

...uh...I wouldn't say that necessarily, if you consider a Lexus RX and a 2011 Camry, all loaded, as junk then damn are your standards high bud

This is better because I like the POWER

[AlexN09]

Haha well you didn't exactly say you owned those!!

[mikethemike]

I wouldn't consider it since you failed to mention those other cars. Not like I knew you owned those cars bud.

to the OP....keep in mind that HP ratings for the 2.5 (175hp) is crank horsepower, not what gets to the wheels (~150-160hp). So keep in mind that adding exhaust , intake, headers...etc can only free up a maximum of 175hp and that's if you negate the drivetrain loss. Obviously nitrous would increase the power, but it's very short term.

Suspension upgrades are much more rewarding in this case.

[DJ_B_Easy]

Im almost twice as old as some of you...

[DAAN.]

umm ... good brakes to stop prior to the accident happening ?

[mikethemike]

Nope. read again. Unless you mean the OTHER car needs good breaks, I'm talking about if you in the AC is about to get hit from a dead stop.

Your reply to my comment sounded like you knew about my cars even though I have no idea who you are...

[stevewaclo]

My neighbor installed dilithium crystals from the Star Fleet web site and can now hit Warp speed in half a block :-).

He's currently exploring options for new brakes...

[BadaBing7189]

lol my first car was a 95 bonneville sseix the supercharged one (she was a beast) got her when i was 16 then when it craped out i bought my ac when it first came out =)

ALSO id recomend the Stillen Light Weight Pulley its worth it believe me

[Irvxing]

i got intake headers exhaust and BDT... The only really noticeable mod out of those was the headers TBH. The BDT claims to remove the limiter... but it doesnt. I messed with all the settings and adjusted the timing safely and i feel it pulls best at stock or normal octane tune... i think havnt really pulled my car lately. then after headers was exhaust. for obvious reasons (combined with headers)at higher RPMS it PULLED. Before removing aftermarket exhaust i spanked the new Tcs. after the Tc spanked me lol.

So you're now currently running stock exhaust with headers and intake?

[UltimaCoop2.5]

Dude dont worry,I exactly know what you mean because im 17 and have a 2010 A/C 2.5s CVT. Just do the BDT AFTER you put on other parts like Exhaust,Intake,Headers, and Pulley.
