Time for a turbo.

[bundy26]

I have a 2010 AC 2.5 S and after 8500 miles finally decided to upgrade my car engine and install a turbo, I really prefer to keep the rest of the components stock ( injectors, compression , etc..). I have a small budget of $2600, I would appreciate any input and if you guys could direct me to some AC turbo build threads that would be great and also what is your opinion on eBay turbo kits. Thanks.

first off.... I AM NOT HATING or TALKING s***...

now that that's out of the way. i still don't understand why people buy the 2.5 then turn around and want to turbo it? for the money you put into turboing it, you might as well have gotten the 3.5, cuz right off the bat you have more power. getting a 4 cylinder instead of the v6 because u wanted to save money, then turn around and spend way more money by trying to turbo it, and then getting results for around what a v6 would have stock maybe even a little more. you could have just gotten the v6 to begin with. then add the turbo and have way more power then the 2.5 would have. and if u want more power, why not trade the 2.5 in and get the 3.5 then start upgrading. it would probably be cheaper anyways.

now again, i am NOT talking s***, or putting anyone down. i know there are members who have added turbo to a 2.5 that are on the forums. i'm just speaking my mind and putting in my 2 cents. this is just something i could never figure out. maybe it's just me, and my way of thinking, or maybe not. i love my altima coupe family, and i wouldn't talk s*** about anyone. i just speak my mind.

ps... if u do a search i think sum turbo threads might pop up. i think i remember sum back in the day before the site got switched around.

When i bought my coupe i didnt know much about cars. i also didnt think the hp difference was worth the money to get a 3.5. ha
I also didnt have the money. Alot has changed in since i purchased my coupe. I cant afford a super car *cough ricky c cough*, but im doing ok now.

As for the Op's question! 1. you get what you pay for. 2600 is a terrible budget. id walk away now. Qr25de's kit was less expensive than mine but he ended up upgrading alot of the parts and the big thing is he didnt pay for labor. My labor alone was almost twice your budget. Also why wouldnt u wanna change your injectors? GAS and AIR baby.

i feel ya.
kinda like washing your car and then having it rain the next day?
yea, bad analogy, but watevs

[dldjros69]

This thread isnt about why 2.5 drivers didnt buy a 3.5. i really hate those threads. Its not as bad any more before it use to be alot worse. i think their 3.5's were extensions of their _______ or lack their of. This thread is about cheap turbo kits. a bad idea imho.

But if u must here is anpther reason i bought a 2.5. i had a dodge neon with 134 hp. i thought 175hp was a rocket ship

[devilmagic]

$2600.. need to atleast double that budget

[srwong]

i think their 3.5's were extensions of their _______ or lack their of.

i'm a chick, so no extension of anything here lol... i just wanted more power. don't believe in 4 cylinders... but as dldjros69 said, u get what u pay for. if u go cheap, u better accept the fact that it might just break or suck fat ones lol

[QR25DE]

Stock injectors wont cut it, you have a lot of reading to do and a big increase in budget to do.

The stock injectors are good for like nothing. You need 470cc+ for 7psi, then increase from there.

What are you going to do for fuel management? Even if you use stock injectors you still need to richen it up when you are in boost. Besides the fact of the injectors not being able to do the job you need something to control them so an Apexi SAFC 2 or Neo or go full out UpRev.

SAFC you're looking anywhere from 200-400 used/new. Uprev, well you're looking at the price of the program/license + tuning/dyno time and finding someone that can tune it or learn the program yourself.

You will need a custom down pipe, IC piping and you will need to figure out the plumbing for vac and such.

$2600 is doable for just parts alone. That doesn't include fuel management, exhaust system, extra things and tuning. That also factors in a s*** ebay turbo, not a brand name one.

Good luck. lol.

Only reason mine got done is because my friend knows a lot about it and it was a lot of trial and error getting everything to work. You're in for a not so easy ride. Even if you get a Spec V kit or whatever, it all needs to be modified.

Any questions? I don't want to discourage you, but what you wrote is just not possible on regular injectors lol. They don't flow enough at all. I had them running for awhile and it was super lean after 3000rpm even with putting the safc +35 across the board. There was no helping it, they were maxed.

Start reading, be warned, total DIY.. but it works, and it's still working today.. perfectly fine.. knock on wood... had to replace things here and there. If I was going to do it again, i wouldn't go the eBay route for these parts.. maybe the basics like piping and manifold etc. But most other "cheap parts" like the turbo and BOV were a fail. Turbo has been fine since I rebuilt it though. Lasted longer than I thought...

By that thinking some might say to the 3.5 guys, "Oh why didn't you go after a 370z" or "Why didn't you go buy a car with a v8?". Simply put, there's more factors that play into a decision than power alone. He has an advantage right off the bat with less weight, better MPG and cheaper mods.

And good god dldjros69, $5,000 for turbo install???!!?!?!??

[srwong]

not true, the 370z is a completely different car, and it's a 2 seater. lol
im not asking why didnt he buy the most power, i was simply saying idk why people get a lower powered car then try to throw a grip of money into putting a turbo into it when they could have just got the higher powered version of that car for the same amount that they woulda spent putting turbo in it.

Yes in technical terms you are correct, they are apples to oranges. I personally look at it as wanting a "type" of car. Such as myself wanting a sexy Altima coupe. I could not afford 30gs for a 3.5, only 23gs, so I went with the 2.5. The QR25DE isnt even a bad motor by any means, therefore future mods would be worth it to such an enthusiast who wants this body style but just a bit more oomph over time.

If you want to get technical, please correct me if my memory serves me wrong, the VQ is not that good for boosting(ex. early model 350z's that tried to be boosted that threw rods). Furthermore I would just like to say that everyone's life is variable. One could randomly land a job while owning such a car (2.5) and be able to do whatever they want to it. When they ask for suggestions, ppl then ask them back why would you do that and not just get X?..etc. Honestly, this discussion is an open loop because if "power" was at the front of everyone's priorities then their wallets would show it. When the wallet can show it is usually when we get such questions, so let them do what they want with THEIR money ya know?

I give crooked looks at people who buy the decked out a new chevy malibu when they can also afford a brand new Infiniti g25...its all personal preference!

For the people such as myself who can only afford what they get, then want to add more power...this is our gathering place. I would LOVE to boost my A/C to 270-300whp because I know its capable and I know it will smoke a 3.5 any day. Just because it could pull a 3.5 doesnt mean thats the reason why I am doing such modifications though. Everyone has their own perception of what they want their car to be.

/rant lol

[6SpeedinCoupe]

^ Not really sure what that means Miss...Just trying not to sound like an a**hole or an idiot all together lol

I've just always been on "this" side of the fence. Always being able to barely afford something you have always wanted, yet will always want more out of in the future (JUST like my good ol' trusty 1998 cr125 dirtbike i've never been able to let go of because of everything i've done to it..race ready).

[srwong]

lol i just like how u worded it. i was just curious as to why people do it. wasnt putting anyone down. thats why i repeated more than once i wasnt talking s*** lol

Well as you can see from my response I didnt base my response on you talking any kind of s**t. I feel comfortable saying that my post will most likely be the thoughts of the general population...but who knows. I, of course, could be wrong like I often am.

Thanks for the compliment though.

[dldjros69]

And good god dldjros69, $5,000 for turbo install???!!?!?!??

It ended up being a little under 9k. But it completly transformed my car from dog shiit to a monster. (sorry)

Scott im running 440 injectors at 9 psi. no issues here. i see u got monster injectors. Ha 9 psi - i never see that, let alone go into boost haha. my shiits gonna last forever.

[Ranga14]

Oh, wait, I remember all the stuff you had to go through now. Forgot about that, sucks.

And on the VQ... I've been told by multiple shops that it can handle up to 450whp stock.

[bundy26]

After reading all this I decided not to boost my car, thanks for shooting that idea down, just kidding too much work.
Thanks anyway.

[dldjros69]

Thats prolly a good idea!!!

[DReed86]

Danny 9K....... $hhhhhhhhiiiiiiiiiiiitttttttttttttttt.... this is why I cant afford to boost my car.... Def dont have 9k hiding in my cushions...

Maybe in a couple year I can re-visit the boosting idea.

Yeah, if you pay retail you won't like the ending cost.

its ok bro i wanted to do the same but as srwong said its just not worth it. like ok for a 4cyl like a mazda3 for ex would be worth it to turbo but the fact that the altima comes in 4cyl and v6, it just makes more sense and logical to get a v6 and then upgrade from there on. at the time the v6 wasn't in my budget but now with extra funds it makes me want to turbo but for ure budget of 2600 thats not much. a kit runs at least 5000 and for that the v6 makes more sense.

been there, thought about it, passed. when i get my bmw in the future, it will be a beast!

[DReed86]

when i get my bmw in the future, it will be a beast!

I have my hearts set on the Lexus Is-F

Nice looking car but damn, they are a dime a dozen! At least around where I live.

[DReed86]

the F series??? I hardly every see them around here and Ive never seen one in White cause of course thats going to be the color I get....

I did see one online that had custom white suede seats in TX looked so sick!!!

ohhhhhh i feel bad for him now hahhahahaa dude it sucks i know. If your on a budget just do some mods make it perform better ie intake exhaust springs "coilovers are better" pulley bd tuner you can do any of this

[AlexM.]

Dude if you really wanna do it, do it. Even if it doesn't make sense, you can be the one to judge that for yourself later. You can always try selling the stuff later

[bundy26]

Maybe next year, I'll try to get more money together.
After I get my taxes I'll have close to $7500,i understrand the whole v6 thing.
Didn't have the money to get a 6 then so I got the four instead, thanks anyway for all the bashing it was fun.

[dldjros69]

Yea man! Ya been here for 5 months for 130 posts. Im talkin 2 2.5 years ago. The ****s will remain nameless but there was a ton of them that actually thought they were cool or an OG just cuz they had a 3.5. Tools.

Yo bundy man sorry to rain on your day. i hope i didnt bash or flame ya. I kicked the idea around for awhile and then pulled the trigger. The cost changed like 5 times too
