that's it. I taste the turbo 2.5

[Nlghtmare]

I am going to have some money to do either one of these and some buddies who are amazing car dudes working on my car.

So as earlier if people saw, someone posted a thread on a universal turbo system. http://www.ststurbo.com/universal_turbo_systems That is the link. It doesn't look or sound too bad. In fact, it seems like it would suffice and do the job sufficiently. If I went with that company, I would go balls to the wall and purchase the "universal twin turbo kit." They do have dyno results posted so it makes the investment a little more appealing.

I would like a suggestion on the sentra turbo(s) that people have constantly mentioned on NICO to fit into the 2.5.

Then there is the custom shop turbo or buying a bunch of random parts and having my buddies do the work, which they are willing to do.

I'm no professional myself and it's apparent, but I know what I know. And what I do know is that this is possible, what I don't know is why no one has tried it.

Side note: There are two brothers in my town that own a 2.5 and a 3.5, both of which are making their cars... well...Try to keep up.

As people have said before that universal kit is garbage. As with 90% of ebay kits...

Next, i dont know what experience level your friends have but in most cases turbos are not a diy project. Im sure they could hook up the turbo and piping but to get all the parts to function together properly is an other thing.

Id suggest going to the custom shop and talking with them and seeing what they can do for you. That is your safest and cost effective bet.

TWIN TURBO on a 2.5 inline 4 hmm ive never heard of that.

Why has nobody attempted this, because it cost some where between 4 to 6k. And thats for about 50 whp.

Well there was me being positive/attempting to be helpful.

Now

bring on Dr. Feelgood the BS Mod

Put up or shut up

uh. ok. haha.thanks for the input.my friends work in shops so I trust them 100% with my car that's why I'm not worried. They're not a bunch of sixteen year old high school students .

But you totally misunderstood me. That isn't a universal turbo kit off E-Bay. Click the link man.

My bad.

Good luck and keep us posted. i look forward to seeing the progress. Im not quite where you are at in the decision process. I dont know if i want to turbo the car and make it fast enough that im not pissy or get a new whip in the next year or so...

[Nlghtmare]

It's cool man. I totally understand where you're coming from. I was thinking the same thing but then made a solid decision I would be keeping this car for some time so I would be wanting to do some serious work to it. Thanks.

[PHENOMenalVinyl]

idk if doing the twin would be a good idea.....ude need the internals upgraded if you throw on alot of boost from whatr i understand. Also i would rather go the way of using the turbos in the sentra like u stated since that seems like a better bet.

[Nlghtmare]

Yea. Come to think of it, the twin turbo idea sounds rather unsafe.I think I'm leaning towards the sentra idea.Any more suggestions or comments?I'd like to see what people think before I go ahead and do this.Oh, and I am doing this.

[Viperjunkie]

Yeah i actually emailed them about making a kit specifically for the coupe. They only replied back with, "try one of our universal kits!!" so i tried but i too was thinking about doing this. IDK, i may just go with SFR's kit.

[Nlghtmare]

SFR kit is 3.5 only. Haha. You're lucky.

[mcheddadi]

do the sentra one, just adapt the piping, go check myspecV (the forum). they have lots of people doing turbo builds as we speak and that should help you out a lot. plus they have custom fuel maps for your motor and they know the best people to go to to have the QR tunned properly since they've been at it for years.

go check them out and report back here. the future of all the2.5ers rests on your shoulder. make them proud!

[Dexion]

Twin turbo's on an Inline block always seemed silly to me, A V block is a better idea for that application.

ahh you're the best.you've been being so positive since before I was even a NICO member! haha.thanks a lot.I'm going to head over there right now and I'll have something to show off this summer!

Twin turbos are cooler though. LawL

Well. I'm going to keep everyone posted.I learned a lot.Here is some information from another forum designed for sentra se-r users.Here is a little information.

[mcheddadi]

forged internals could be good if you plan on boosting it more than 100hp (I hope you do because otherwise it would still be slower than a 3.5SE )

I found some stuff about that:

lol is that safe for a CVT though?100 hp would be sick.

wait you have a cvt????

now i dont get it but ur def not gonna be able to do twin on cvt itll ide easily.....ur gonna have to do a ton of wrk to it

[mcheddadi]

do a manual transmission swap.

check this thread out. The guy is the first ever b16 sentra (2007+) specV to go turbo on his 2.5L qr25de and he is pushing 325WHP on 11psi of boost. Cost him 4335$ with install. and he didn't even upgrade the internals of his motor and he is running stock compression.

vinny ten told me he just did a sentra and its pushin over 500hp s***s crazy.......wen i told him i may turbo he was like please call me when you do bc i would LOVE to do it lol but i got the mt thats y

[Nlghtmare]

Haha. I don't want to have to do a manual transmission swap.CVT for the win.Please no arguments about that now.I've learned so much about what I can do to the 2.5 since I started this thread.You'll see!You'll all see!

I don't know what I'll be pushing but I will definitely impress you all and hopefully get others to follow and do the same!

on and mc. your last post in this thread can only further prove this is possible on the 2.5 altima coupe right?

[mcheddadi]

hell yeah its possible, should cost bettween 4K and 6K~ and you'll be pushing insane amount of with through your 2.5L so, what are you waiting for !

the day a 2.5S pwns all 3.5SE is near lol

[ItsEcko06]

LMK also! i have the 2.5s cvt. i just know that you will need transmission coolers for sure. i know where i can get a good priced turbo for the altima too! i think a small one for 200, not sure what brand but if turbochargers.com has it, its gotta be good.

[DarkScorpion]

But I'm pretty sure you're going to have to do a CVT swap from a 3.5. I read somewhere on here that the 2.5 CVT is a lot weaker internally than the 3.5, and that the 3.5 CVT should be used if you plan on boosting.

[dldjros69]

So what kinda engine degradation is going to be had running 11 psi? I thought 5 psi was the highest?

Would 11 psi still be a daily driver?

[AkAd3MiKs]

normally the safest boost to run on a daily driver with stock internals is 5-6 psi. Ive seen people run 10+ psi but they have a really good fuel management system and thats only for a short time. So what made you go with a turbocharger and not a supercharger? Ideally when you have an automatic its best to go with a supercharger. But if you really wanna go turbo, by all means do it. One more thing, i was looking at that sts universal kit and it dont look to trusting. First off, it looks like one of those ebay kits and second why are the turbocharger so far from the manifold? Correct me if im wrong, its been awhile since I was into all these things, but wouldnt that create a lot of lagg on the turbo? Also to help you out, I heard that the 2.5 altimas has the same engine as the sentras? So you might be able to use the turbo manifold from a sentra. from there on you can peice all the parts together yourself depending on your goals.

Nah, those STS kits are pretty legit. Their the only company (as far as I know) that makes rear mounted turbo kits (since I believe they hold the patent on the design). Turbo lag is the only major drawback of the system, but it's a great trade off for simplicity as far as running lines, getting everything to fit, keeping the turbo itself cool (since it's not under the hood) etc. STS is not some random universal company, they've been around for a while and have been featured in many magazines and even on Spike TV's Powerblock. Check it out - http://www.corvetteblog.com/ar....html

Edit: actually, that video is dead, but the blog is still good! But basically, STS is a pretty well known company, especially in the muscle car world.

Edit number 2: At this point, a supercharger would be much more complicated to strap onto the QR. A supercharger would require much more fabrication since you need a mounting bracket, and judging by how much room there is under the hood, a supercharger isn't as practical as a turbo. At least with the turbo, there are already a few manifold designs out for the QR and a wealth of information from the boosted Sentra guys.

[AkAd3MiKs]

i still dont know about the design of the system. If you put that turbocharger that low, theres more chances of it getting damaged. I mean if you notice most of the cars that has these systems are drag cars only not no street daily drivers. Most likely youre gonna drop your car or you may already have done so. You have to take into consideration the speed bumps and what not. Also, you agreed about the turbo lagg, so with that I dont think its a good idea. If you look at the dump tube, if a rock chip gets in there then your wastegate might get messed up. I have a 2.5 cvt also man and in the near future I will go with a supercharger. I think I also read somewhere here that there is a supercharger that was made to fit in tight spaces. But if you really want to go turbo, then try to see if those manifolds would clear. If it does, then I would go that route and you would be at a good start.

[DarkScorpion]

Nah man, not even close to all being drag cars. Most of their systems are engineered to be daily drivers, even the twin turbo systems. Granted, the twin turbo systems might require forged internals, but that doesn't mean at all that it's not a streetable car. Also, with the location, the odds of a rock doing significant damage to any of the components is slim to nil. Take a look at the installation photos - most of the turbos themselves are located behind/above rear axles so speed bumps and curbs are very unlikely to do any damage. Also, notice how in the photos many of the cars with installed systems are daily drivers, definitely not a drag only system.

You're more likely to hit your muffler or bumper on a curb while backing up before you hit the turbo or any of the piping. Same with driving forward - if your car is lowered, you're more likely to scrape other things besides the turbo since the turbos are actually mounted relatively high in their systems. They put quite a bit of R&D into their designs, as they also realize the consequences of a rear-mounted turbo.

Check this thread out over on Maxima.org: http://forums.maxima.org/super....html

This was the first (and likely only) ever rear-mounted turbo'd maxima. Check out where the turbo is - it's actually above his rear sway bar. He's more likely to have that get messed up by a speedbump than the turbo. There's also a whole lotta discussion on turbo lag, how he ran the piping, how he's going to protect the air filter and turbo from water/rocks/the elements etc, and how he oriented everything

[michaelthepsycho]

Yup, I agree. STS is well-known and at least somewhat trustworthy. I've been on various Corvette forums and they have lots of STS kits running about. I've even seen a G35 running a STS kit. Google around, you'll notice that they're okay. The advantage is that they don't need coolers and don't take up engine bay space. The downside would be lower exhaust speed and lag, which they make up for using smaller twins.

[Nlghtmare]

Is thread thread suggesting that a 2.5er should use an STS kit and not the sentra kit now?Is a transmission swap still needed?

[DarkScorpion]

I say you try setting up a turbo using a turbo manifold for the sentra QR's. See which ones will fit under the hood and what needs to get custom fitted/fabricated. The STS kit is a rear-mount turbo kit - just as much planning and fabrication will need to be made. Search around to see if you can find discussions about the 2.5 CVT vs 3.5 CVT. I'm only going by what I remember reading.
