linky no worky

worst placement for a turbo ever.

Im sure you figure that because either someone else said it, or you just assume 50lbs of iron and steel cant hold up to "the elements". The inlet runs air down from a snorkel and dry sock so air wise its fine. Water wise...shouldnt have a problem...lots of turbo cars drive in rain all year long in Washington and none take a crap. The placement itself has about the same amount of crap flying around as a normal placement of a turbo and is as efficient as the worlds most efficient manifold-turbo kit for the Hona k-series. So why is it the "worst placement for a turbo ever?"

How much boost is obtained from this particular set up? I have no doubt that there are some HP gains with the turbo set up and that placing the turbo charger underneath the car rather than squeezing it in the engine bay may be an easier install. But I think the turbo would more efficient if it weren't so far from the trottle body and if hard tubing were used vs the the corrugated tubing that is posted in the pic. In my opinion there is too much distance the compressed air must travel from the turbo to the intake and by using flexible corrugated tubing the compressed air would cause the flexible tubing to expand thus decreasing the velocity.

Otherwise I think the turbo kit an awesome bang for the buck power mod and sounds cool.

You would have so much lag from it being so far from the intake that by the time it spooled up you would already be at your destination.

Don't even get me started on having it underneath the truck for all the rocks and crap you drive over to kill it.

And we though it could get no worse than having our alternator so low in the engine bay.

I somehow SERIOUSLY doubt that the original poster has any interest in offroading whatsoever.

Actually I am focusing it for offroad desert racing. Mainly simple desert dirt/rocks/dust. It really shouldnt have much of a problem in these conditions. Turbo's arent as fragile as many think.

As for the corregated tubing...your mistaken on which part is which. The corregated tubing is the air inlet from a remote filter to the turbo inlet. The hard piping that goes through the side is the intake piping (the pipe the intercooler would normally be mounted to), and the big pipe connected to the turbo is ofcourse the exhaust.

Placement from the throttle body doesnt have anything to do with turbo lag. Turbo sizing and air flow make the real difference. As long as there is exhaust pulsing through the exhaust the wheel will be spinning (its small enough of a turbo) so therefore lag is almost none existant. If the trubo is upgraded to a larger one, the lag can be increased, but that is commonly fixed by alcohol or methanol injection, which ofcourse helps spool.

The HP numbers for this kit are as follows:

Stock 3.4L V6 Tacoma: 140whp/178wtq

Boost: 4 psi
Rear Wheel Horsepower: 224whp
%'d increase: 60%

Rear Wheel Torque: 278wtq
%'d increase: 59%

Boost: 12 psi
Rear Wheel Horsepower: 343whp
%'d increase: 181%

Rear Wheel Torque: 391wtq
%'d increase: 155%

Ok, do a search, you will get the same advice from me as every other person that wants to turbo an X. Don't come here expecting us to "atta-boy" pat you on the back...it's NOT GOING TO HAPPEN.
Go out, spend the coin, and prove us wrong...If you look @ the 4x4 section you'll see a sticky about converting a 2wd to a 4wd, it was always said that it was too pricey, yada yada yada, well we were proved wrong, and it became a sticky.
So go out, spend the coing, prove us wrong, but until then

ETA: fucking noobs

Listen, I was asked questions and people made un-educated guesses and assumptions. Therefore I came back and let them know the facts of the kit and some information they ASKED about.

just a generic query into remote turbos as i really only have the basics down:

a turbo is basicaly a turbine compressor driven by another air source (exaust in the case of the remote turbo?)? wouldnt the air between the turbo & the intake already be there so when the demand is put on the turbine the preasure would rise substantialy fast?

sorry, my only experience with turbines is limited to jet turbines (F404-GE-402 type ) so i'm thinking large numbers. as for the rocks & stuff wouldnt it be protected somewhat by the armor underneith?

My current experience is with the F404-GE-F1D2 ( ) and I'm wondering about the heat. Turbines really like to work with expanding hot gases and I would think you would have some thermal losses by the time it got way back there.

Ive been on the site and looked around, supposedly they size the turbo specifically for placement at the muffler area and take into consideration heat losses (and therefore density change) when the gasses reach that point.

Thats true Kavett, I think on the site it said full pressure is reached in a fraction of a second so I wouldnt call that much lag at all.

Since it takes the place of the muffler, its way up there kinda above the rear axle, so I would assume its pretty safe, and you could probably fab up a little skid plate for it easily.

Doesnt seem like an impossible job at all, and if someone had the time and $$$ they could have a one of a kind X.

The small amount of lag caused by the distance the compressed air has to travel is pretty negligable. One good thing about the remote placement of turbos is the fact that the air is cooled down a lot more than if the turbo were mounted close to the engine.

I did some research on the this concept and found the tubo kit website: ststurbo . It looks as if they have done some R&D on their turbo kits and have them for other vehicle makes. Unfortunately there isn't a kit for an Xterra but I did notice that a universal kit was available but the fuel mapping and other tuning will have to be done on your own.

So I have a question. I've owned a car with a turbo in it before, and I've driven several since then. I've experienced lag in every turbo'd car I've ever driven, and none of them have had an STS-style system and they all experienced lag to some degree. Explain to me, with the turbo being so far down stream, how they can claim that there is no noticeable lag? Just wondering.

I didn't see where he asked you for your advice. Seems you gave that away pretty much freely. Here, I'll do the same. If you don't want to add something meaningful or constructive to a topic, then don't post. Move along. Pretty simple really.

Check this out. This is something even better than the STS. I personally dont see a problem with the STS system, but look at this kit this guy is putting in production for the Tacoma's! Its amazing fab work. I'm going to see if he plans on building one for the xterra.

Likely not.

He made it for the Taco because people will buy it.

You have a lot to learn about this board padawan.

ChefTyler, if every Turbo application car you've driven has Lag maybe you shouldn't be driving them? People like you make this forum lame.

Bama,

How many cars with turbos don't lag besides a 911? When driving our chipped Jetta 1.8T you really feel the lag and then the force when the turbo finally kicks in.

unless you get into bonafide "sports car" performance (and price) all turbos are gonna experience some degree of lag

Well socalpunx, my co-workers Nissan SE VSPEc has no lag what-so-ever. It all depends on your set up and if you have the buck for the bang. Hell, even the SRT-4 for example; you ever felt lag in those? I have not.

There's not much turbo lag in my Mazdaspeed6. Probably less than a 1/2-second. Its TMIC and other intake piping are all very close to the throttle body, so it doesn't take long to pressurize the system.

With the length of pipe used on the STS, there must be some amount of turbo lag. That's a lot of air volume between the turbo and the throttle body to bring up to pressure. But then again, maybe the turbo is big enough to react quickly.

I wonder what the turbo efficiency map looks like.

I think the only part that really scares me about the whole "remote turbo" thing is the fact that you have to run an oil line all the way back there and a return back to the engine. That is a lot of oil line to worry about, and flying debris could cut it and kill your engine pretty fast.

Actually, I think I was pretty much spot on. This post (topic and subsequent responses) pretty much confirms it. The feeling I get, and a lot of other Xterra owners get, is that this board is over-run with a bunch of 4x4-centric hicks who like nothing better than to post about why this or that application or device sucks because it would get broken or hung up off road, or because it serves no real purpose on the trail, or simply that this has been posted about before and likewise dismissed before so do a search, all the while forgetting that this is neither a Xterra 4x4 board, or that not everyone buys second rate IFS SUVs (less so with the 2nd gen ) just to make a hobby (and significant personal investment) into making up for Nissan's obvious 'design oversights' - which are many, if you only see your rig as a Jeep rival.

And finally - while I've not wasted an entire 5+ years on this board, it doesn't take long to figure out what made of. I came here about a year ago looking for information on fog lights (of all things) and I personally could care less about the 4x4 capabilities of my truck. I do however care about getting to and from the trail head, with a trailer in tow, and a kayak or bike attached. I can't get that kind of utility out of a Honda Civic, and that's in a nutshell why I own a Nissan Xterra. It's also why I didn't buy a Jeep Rubicon or any other vehicle specifically designed around it's 4x4 capabilities. So to posters (and readers) like me, give us a break. Let us read redundant posts in peace. You don't see me getting on one of the 8 million Shrockworks bumper install posts and screaming "do a search, this topic has been posted 8 million times already" do you?

Edit: spelling for smart 4x4-centric hicks that caught it.

Get over yourself. Honestly.

If you have read through any decent amount of posts on this board you would know that the people that post here regularly are PRIMARILY INTERESTED IN OFF-ROADING, if YOU can't understand THAT find another board, period.

That is all, thank you.

I think its funny that people who have "read" a lot of posts or have "driven" a lot of turbo cars think they know a lot about them.

My girlfriend "drives" a lot of cars too, but she doesn't know the first thing about combustion, or sparks, or compression...not to mention the fluid dynamics of exhaust and air flow...

Also, just because someone may appear "new" in the forum world like XOC, doesn't mean they don't know about vehicles. For all you know, they could be an automotive engineer and know a whole lot more about how things work then any of you do. There is now need to get upset about any of this really?

Cornice Jumper go jump off a skyscraper, but first go back to English class and learn to spell, You are a XOC virgin and do not understand the type of bashing that goes on here. I see you did not receive your honorary XOC "How to bash on threads" book. You will learn this forum quickly for defending someone, REALLY quick!!! But have fun!

I hate to say it, but they are right. Most people on here are dicks to anyone who doesn't want to go all out offroad.

It is Xterra Owners Club.. not Xterra Offroaders Club.

Don't get me wrong, I've put more cash in to offroading mods on my truck than it is worth, but I still think most people are asses on here :rolleyes:

I think I alluded to that with my comment about the 8 million Shrockworks bumper posts there are, but hey I didn't honestly expect ya to catch that.

Ever wonder if the reason the only people posting on this board are primarily interested in 4x4 is because of the assholes among them who go out of their way to ostracize and dismiss those who's interests are other than 4x4ing? I wonder what Nissan would think of some of you folks who purport to 'represent' the Xterra community?

Hey let's talk about turbos again. I suppose lag is relative to how you drive the vehicle. I've got a Saab 900 Turbo and for example if I'm in 3rd at 35MPH and floor-it I've got nothing. If I'm in 2nd at 35MPH and floor-it it rips. I think any turbo is going to have some lag, you just learn how to avoid getting into that situation by keeping the RPMs in the right range.

amen broham

All turbos lag. In the Bugatti 16.4 has a small amount of lag. Having the turbo that far from the engine will create a shit load of lag. I have driven a MAzdaspped 6. Guess what it has lag. I have driven a WRX guess what it has lag. My friends SPEC V had lag. Hell my stock spec V had lag. All fucking motors have lag when they shift.

Stay "Tuned",,,,turbos to ALR with less than 4 pages of "lag"

I'm kinda joining late on this one, but you are not correct here. Bigger turbo takes longer and causes MORE lag, than a smaller turbo. It takes longer to spin up, but provides more pressure. Smaller turbo is faster to spin up but less pressure. That's why there are cars out there that run a bi-turbo. Bi-turbo is NOT twin turbo. Twin is 2 turbos the same size, and bi-turbo is a setup of 2 turbos, where one is small to reduce lag by spinning quickly, the other large to provide more boost at higher RPM.

are they put in series or in paralell?

Hmmm...looks like there is at least one '00 Xterra running around with a supercharger on it...see this thread on Xterrafirma....pics of the engine included...
supercharged 1st gen Xterra...

I did a poll on XOC...it seems of the people who responded, about 20% said they had NEVER offroaded.

So - given that the non-offroaders probably are not checking the boards as often as the hard core guys...I might guess that the majority of XOC-ers are off roading at least a bit, but that the board has thousands of registered NON-Offroaders.

I also agree that XOC is Xterra Owners, not Xterra Offroaders, but, lets face it, all you see in these responses is the reply of the respondents...the silent majority is invisible here.

So if 12 posts attack you for washing your truck or [Shudder] slamming it, etc...there are over 12 THOUSAND members who did not.

I think it helps to remember that.

Its a free country, and there is freedom of speech...but you only hear the speaches of those that speak.



And yes, the smaller turbos need less volume to spool up, so they fill faster (Respond with less lag)...but ultimately, can't generate as much total boost.

You can plumb them to fill together, but, that typically robs the little one of flow, so the are typically set up to fill the 'lil guy, and THEN the big guy.

well i personally would like to see more support for people that are not serious offroaders. I have taken my X to the limits of a 2wd lsd equipped vehicle and its lots of fun, but i really give a rats ass about offroading. I like the utility of my X, and it tows my boat great. And there are obviously others like me on the board. Anyway, i dont want to piss people off.... if you have $10k of mods on your X and rock climb with it, then much props to ya, would love to go for a ride! But call me crazy, im interested in seeing a turbo X just as much as im interested in seeing a solid axle converted offroad beast.

Wow, this thread went kind-of nuts. I do agree that alot of the posters on XOC are hicks...and seamingly unintelligent and uneducated hicks. While most (i know there are some, you dont have to post to make it known) of you guys know nothing of what you even own; in terms of how it works and how it works with other mechanical parts on your rig. You simply know it does something good and you will talk about it like you know the very logistics of even what the engineers of the said product where thinking while designing the product....was that too fast for you? To many nouns, adjectives, and verbs?

If you know anything other than what you have heard, please post up.

Anything dealing with turbocharger's is an "Educated ONLY" thread. It is not a thread to be trolled by the ignorant, the 'seat-dynoer's', or the 'im-a-lag-doctor-because-i-heard-about-lag-and-turbos-in-the-same-conversation' guys.

Go back to school Dr. Turbo guy.. :rolleyes:

With comments like that, you have now been labeled a troll. Good job. Move to Louisiana cause Texas dosent want you.

I got the Carne Esada, It is Awesome!

I guarantee that once the people that talk the trash, drive an x equiped with one of these turbo systems installed, they will cease to talk the trash. set up right they work.

I know they work, i drove a Tundra on 33's with one and it was awesome. However, i think I would rather make my own turbo kit for a fronty/xterra...since no one makes one yet and Toyota has a nice turbo/offroad following for the Taco/4Runner.

The turbo is sized just right that there really isnt any lag...basically if you want to really know what lag is its the ability to feel the transition from stock hp to full boost. If your running a 1000 HP on a engine that was originally a 200hp I4 car, then yeah since there is a large turbo being spun, you will feel the transition of 800hp difference. However, if your using a well sized turbo on a 3.3L V6 with originally 190hp...maybe pushing 8psi, you will likely be around 320-330hp. So you will feel less of the transition of the 130hp difference. Plus since the spool will be faster due to the smaller sized compressor wheel you will feel less lag. Then there is the tunning aspect, if it tuned correctly you can experience a very very small amount of lag in the form of building power...not a sudden jump to peak HP.

Well kid actions speak louder than words and all that you have done is speak of your superiority of everyone around you, if you want to have any chance at credability within this or any other community follow through on what you started, if you think a turbo is such a good idea go ahead and do it. But untill that day has come because you only sound like a whiney little prick.

Oh and by the way there are some people here that have actually graduated, unlike yourself, its all about the follow through.

Being graduated doesnt have anything to do with 'who's smarter'. The ability to interpret what you have learned and put those interpretations to work for yourself is what matters. I am not trying to sound better than anyone else, its just a vice of mine.

Otherwise, why dont you STFU unless you have something positive to contribute to the conversation instead of following the lead of your fellow wheelers trying to shut the conversation down or turn it into somesort of arguement.

Personally, i think a well sized and well engineered turbo system will do wonders for the Xterra, anyone thinking otherwise is either too proud to say the 3.3L could use some more help than a little 4psi supercharger gives or are too ignorant to realize what a turbocharger really has to offer other than lag.

Look around, the Xterra isnt quite the most powerful or most capable SUV on the market. While i personally agree that the X is one of the more capable SUV's it still has its strengths and weaknesses. One of the biggest weaknesses is 200fttq at the CRANK...which translates into maybe 180tq to the wheels...in a 3.3L V6 platform, thats nothing. With a turbo system there is the ability to fine tune your powercurve to allow for lots of torque very low in the RPM range...as low at 1,800RPM. It all depends on how you design the kit. A large turbo will do nearly nill to make power down low...yet a small one can make power down low where it is needed, and leave the truck at stock driveability. As someone else stated, "a small turbo that would not make lag would be too inefficient at higher rpm's." This is true to an extent, but how many of you spend your days driving around at redline outside the turbo's effiecient range? Probably none...hopefully.

Therefore, if you use a small turbo to make plenty of grunt down low you will be fine with driving around daily without much of a notice in change of driveability. The power will be made low, right off of idle. Most of you, if your like me, you shift around 3,500-3,750rpm...which is really all you need unless your gunning it all over the place...in which case, you shouldnt be driving an Xterra. So you have plenty of power where its needed.

I am beginning to wonder if anyone is actually reading this or are you just scanning through it and sticking with your own biased and uninformed opinion that turbo's are bad??

Turbos are good, ok.
Have you seen these yet? T-CASE GEAR REDUCTION
Anyone wanting GRUNT will use these .. Oh, my bad. You don't have a transfer case..

T-case gears are good for crawling and low speed wheeling. NOT anything having to do with the desert or sand driving. Not to mention the risk of mechanical failure at highway speeds in 4wd.

if your gonna talk like you know so much, at least get the fucking specs right you ass clown

the X has 170 hp not 190 as you stated

whats a turbo???

Now that you guys are bitching over the internet with each other. Why don't you all just sit down get a chill pill and

Have you realized that this bitching is useless yet? Your egos are fricken gynormous but your average penis size is about an inch and a half... time for a pml eh?
Your trucks are no better than anybody elses if someone wants a lift go for it! A turbo go for it! People will do whatever the fuck they want with their trucks

Unless you are someone who works with powerful cars on a daily basis being NA turbos or supercharged then you have no say

Fuckin clowns

Mark, one needs only to review your recent posts and see what type of info you've gathered here to realize you don't know shit from shine-ola about your truck or most things in relation to it. Just take it easy tigerpants..

I know but i dont come in here ranting and raving about how a turbo would or wouldnt perform because im smart enough to realize I DONT KNOW SHIT ABOUT ANY OF IT

Unlike others in this board I don't try to think I know shit, thats why im trying to chill some of these fellow dumbasses out

Actually I do know shit from shine, I shine my boots all the time...

My previous car was a supercharged grand prix cam and all soo I do know a little

I thought you'd get a kick out of that

I gotta get to redline just to merge into highway traffic here in Chicago (33" tires), people here are nuts!

Highway spees in 4wd? Don't use 4wd then, and if you need to use the 4wd, then you shouldn't be going highway speeds to begin with!

It's funny pullin your leg, man. Don't take most of the folks seriously on here, that's just good ol' XOC.

I know, haha, i like the fact that most people dont know what they are talking about but still try to prove a point, it makes me feel good to know i am smarter than people twice my age. hahaha, i know im a pompus asshole, but hey that what XOC is full of right, so i fit right in.

Nah, im just kidding, its all in good fun. XOC is just like any other forum. the replies i like the most are the ones right after i make a technically challenging post, then they come back with some namecalling and a specific number i may have misplaced...they tend not to see the big picture. ;-)

i do see the big picture: those minute details that you fucked up are really important

ask the guys who built the mars lander

Um, seeing that those were measurments dealing with something that was remote controlled from 50 million miles away...not the 20 hp difference that i stated which could be lost due to altitude or even tire size...it doesnt matter. You're an idiot, now stop talking.

You guys should meet at the monkey bars tomorrow, 3:00.

I love it you can always see who knows what by how many trucks they have...what I only have two uhhhh .

Staying on topic:

Turbo's are great if you want max performance for:

A. WOT
B. Street Use
C. MAX #'s

I believe that if there was any research that was worthy of investigating, it would be an efficient roots/screw charger that was intercooled. I could care less about peak #'s I want to see how the overall hp/tq band has improved.

You can't beat max boost at 2000rpm. I also know that trying to deal with lag and boost associated with a turbo while creaping over rocks is a real work out for both feet.

If someone wants to build a 2wd street racer X, then turbo the bish. Do it, show us, and make a sticky. If you want something to scoot without even 1 second of lag- go roots. I don't believe that anyone is going to develope a variable ratio turbo that the common-folk want to invest in.

Kenne Bell on top of the VQ40 would be a nice suppliment to the power it already makes.

I would rather build a sleeper VQ with a quiet blow off valve that will pull like a Caterpillar (sp corrected )from the hole than have a whistling dixie machine and 2fast2furious blow off noises.

Well said

Some truckys for that one..

I just read this whole post. The jeep forum almost had the same thing, verbatim.

It is sad when you get a good bunch of people with a common interest together and it turns out to be a testosterone filled cyber-brain-wrestle.

1. There was alot of incorrect, misleading information stated in this post.
2. Accept the fact that most off-road enthusiasts don't make forced induction, compression ratios, and anti-lag solutions a big part of their 4xEducation.
3. More people need to read and be humble. A closed mouth gathers no foot. If you are not a subject matter expert, just wait for someone that is. Don't just post forum clogging guesses because you drove a turbo car before.
