XS Engineering turbo kit

[mrace240sx]

Hey all, I have scrapped some of my plans after reading alot of the turbo talk on this forum, I am now seriously thinking about buying this turbo kit from XS Engineering. Does anybody out there have this kit on their S14? My car is a '97 240sx coupe.
Ive been looking for more information on the net, reviews or whatever and cant seem to find much.
It bolts on to a stock 240sx and adds up to 70% horsepower... thats #### impressive from a turbo charger imo.

Here come the questions, hopefully somebody can help me out.
1. A magazine article I read says it runs at 6.5psi, that seems to be low enough not to damage a stock KA24DE correct? Will this product put excessive wear and tear on my engine?
2. The price Im looking at says $3999, has anyone out there seen it at a lower cost.
3. What other modifications will I need to make once I turbo my 240 to compliment the added boost? Will I need to purchase anything else besides what comes in the kit?

Any turbo information would be great guys, I need reviews or recommendations, and prices too.
I plan on calling XS engineering sometime this week to discuss their turbo kit so hopefully that will shed some light on my turbo-ignorant self <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> but I also wanted to post here because it seems alot of you are running turbo KA's.

Thanks,

Hey, I have an XS kit that I am having installed this Friday, but I do have all the info you need. I did lots of research before buying this kit, talked to owners of different kits, and I took all things into consideration before purchasing it.

1. 6.5 is the max psi that you can run on this kit. Anything above and you are in serious danger of detonation. If you go to the XS website and click on featured articles, there is a really good article on a turbo S14 with this turbo kit. It says that even a 4 psi the car is completely transformed. I went with a Greddy profec B boost controller so I can set the low boost at 4.5 for daily driving, and the high at about 6.5 for when I wanna race. It is reliable in this configuration, but you MUST get a turbo timer if you want it to last long.

2. Do NOT pay $3,999 for this kit. www.i-m-racing.com (intense motorsports) sells the kit for $3,395.

3. The kit comes with a Vortech FMU so you don't need anything as for fuel. The things you need besides the kit itself are the gauges, the boost controller (optional), and the turbo timer.

Also, for your knowledge (and so the other guys don't get upset). You can buy an Nsport kit which brings a couple more fuel components, and it will cost you a little less. This kit does offer more horsepower than the XS kit (240 rwhp), and has less bends for the i/c piping. I didn't get it because I think it's ugly and I drive a show car, but if you are all go, then I recommend this kit for more HP and less $$$. I don't recommend F-max because I talked to some owners who hate the kit. Also, their manifolds suck. I hope this helped you out.

Thanks for all the info Bomex, I was hoping for a few more replies but Ill take what I can get.

I am really torn about which way I should go with my car. $3300 is alot of money.
I originally intended to just do the intake, catback exhaust w/ headers. Do some frame stiffening, throw in a short-shifter, and then put a small nos fogger on it. I figure if I can get up to about 190hp and then hit the nos when I need it I would be alright.

I know alot of people on this forum are dead against nos but I havent seen anyone explain why.

The NOS Rant. &nbsp;By Jeff240sx.
Once upon a time, at a drag strip, I saw a Camero running a 350 with a 400 shot of NOS. &nbsp;He ran fast and hard. &nbsp;Then he smoked, and smoked and smoked. &nbsp;Then his hood dipped inwards as he crossed the trap. &nbsp;He ran hard, with NOS, and got a 14 second 1/4. &nbsp;Then he opened the extremely hot hood, and saw his valve covers were melted, and he cried. &nbsp;I saw him about a week later, and he said his piston melted to the cylinder wall. &nbsp;This snapped a rod, threw a valve and f**ked his engine.
Now, I know nitrous has been getting safer to use, but it is unreliable power. &nbsp;What happens when you hit the button? &nbsp;You activate a servo to open the bottle, and run N2O through the lines. &nbsp;This supercools the lines, as n2o is cold. &nbsp;Once through the lines, it mixes with air or fuel. &nbsp;Either way, the engine is not ready for it. &nbsp;The air/fuel ratio gets cut way back, and then the MAFS says &quot;What the ####. &nbsp;Cold. &nbsp;Oxygen. &nbsp;FUEL!!&quot; &nbsp;to the ECM. &nbsp;Then the ECM yells at the fuel pump to supply fuel. &nbsp;Then the ECM retards the ignition. &nbsp;The fuel flows through the lines, the engine is getting lean as ####, and all the fuel the little pump can make flows out the injectors.
What can go wrong? &nbsp;The switch doesn't work. &nbsp;The switch delays, and injects n2o when you don't want it. &nbsp;The cold lines, weakened, breaks, and EXTREMELY flammable n2o sprays everywhere. &nbsp;Engine leans itself to death. &nbsp;Engine retards ignition to detonation point, when sufficient fuel isn't ready. &nbsp;Heat from extreme combustion temps frys pistons, valves, plugs. &nbsp;Fuel system can't handle it.
Why I don't use it. &nbsp;Cost (explained later), insufficient returns for high risk, un-reliablility.
Turbo vs. Nos. &nbsp;A TURBO is a one time, costly INVESTMENT. &nbsp; Once you spend $2-3k, you have more reliable, less risky power. &nbsp;And at 100hp for $2k, it is $20-30 per horsepower. &nbsp;For 100,000 miles.
And NOS, it is a one time, $500-600 dollar ITEM. &nbsp;Followed by the NEEDED forged pistons. &nbsp;That's another $500. &nbsp;Then you pay another $10-15 per pound of n2o. &nbsp;After you pay your $100-150 for the bottle, you now have almost $1300 for the NOS setup. &nbsp;This will net you 50-75hp. &nbsp;This is $17.33 per horsepower, for about 10 one second shots, or nearly 1 mile of 75 hp. &nbsp;Then the costs is about $2 per hp with refills. &nbsp;After 10 or so launchs, there is another $150.
So when does NOS and turbo costs equal out? &nbsp;After about 6-8 fills. &nbsp;That is 60-80 launches. &nbsp;
So it's your choice. &nbsp;Are you gonna do more than 6 miles worth of launches? &nbsp;Are you gonna pay $3 less per hp than turbo upfront? &nbsp;Are you ok with unreliablitly and risks?

N20 isn't flammable

[Jeff240sx]

I've gotta argue this one. At the track, when you run n2o, you need certain flame-retarding materials around the bottle, and it needs to not be located in the cockpit. Also, you need a flame extinguishing method.
Also. OF COURSE N2O IS FLAMMABLE!!
Something that is not flammable is Helium. You don't run helium into your combustion chamber, now do you? N2O is air. Air is flammable. N2O is 38% (i might be off by 2%) oxygen by weight, as opposed to 22% in ambient air. No Oxygen, no flame. Oxygen, flame. More Oxygen, More flame!
-Jeff

EDIT: Nitrous itself is not flammable. &nbsp;If you really wanna be technical. &nbsp;BUT! &nbsp;When heated, n2o decomposes into OXYGEN and nitrogen. &nbsp;The heat will break the oxygen separatly, and the heat will also ignite the oxygen gas byproduct. &nbsp;BOOM! &nbsp;I have read up on nitrous. &nbsp;Saw it in action mess someone's day up, and most importantly, took 3 years of chemistry.

Guys. I know N2O isn't as bad as I made it to be. I understand that. It could be. I am showing the worst point of NOS to make A point. It is not worthwile IMHO, and someone wanted a reason. If you wanna do it, chances are these things won't happen as severly as I said. But if they do... I warned you.
-Jeff

Well, suppose you get a free NOS kit and set the purge to spray your intercooler with freezing cold N2O. Is that dangerous?

[West]

Yes very.

N2O can suck it.

Well, unfortunately &quot;The Fast and the Furious&quot; glorified the use of N2O. So now more than ever, riceboys all across the country are spraying away thinking they are Ja Rule or Vin Diesel.

[Jeff240sx]

n2o is dangerous, of course. But there are shops that specialize in tuning a motor to accept nitrous. There are special saftey precautions that they take to run as much n2o as possible, yet maintain reliablility. n2o is great if your motor is setup for it. I have seen cars run perfectly off NOS. I raced a Mustang owner who spent around 5k to accept a 300shot of NOS, with the ability to run 400. I was in my 'Vette. I had him by about 3 car lengths until his engine got high pitched, he zoomed by me, and all I could smell was NOS. He said only once did he shoot 400hp worth.
But as far as adding NOS to an otherwise stock engine, or even, god forbid, USING the n2o for it's only source of power, is quite dangerous and I am HIGHLY against it. Running a 50 shot of n2o on a stock engine is just like turbocharging a stock engine. It can be bad. You need a tuned NOS motor, and n2o acceptable cams. Running 100hp shot is like pumping 15psi through a stock KA. That IS bad.
