Default hey, i gotta question bout nitrous..

hey guys i'm kinda new here, haven't posted many threads or anything. i have a turbo xs turbo back exhaust, a dual stage boost controller, and an apc stage 1 clutch kit.. i dont have too much money to spend on the car between the wife an spendin money an everything. i want some more power, an i need to do some audio work in the futre. i was thinking about getting a nitrous kit, but i don't know if i should get a wet or dry one, and if i'll need anything else to buy to be on the safe side.. any suggstions will be greatly appreciated. thank you.

well you dont have much money to spend but u want nitrous? no offense in the end youll be spending more money on a new motor look for a different route. Now if you want to do it the right way get engine management FIRST do the basic fuel upgrades and have a PROFESSIONAL install it then I guess get a map tuned for it. I dont think there is much else to be on the safe side. Personally I would get an exhaust first. If its possible get rid of the cats

you could probably get like a cobb AP or something for about the same price as nitrous and its a lot safer and almost the same power to be gained (w/ up and downpipes)

personally I'm not a great fan of NOS, I think the money is better spent elsewhere. If you want to shoot off huge amounts of NOS in your car you'll usually end up running lean, plus all that cold air being fired into the cylinders ain't great for the engines. But anyways, if you want modifications to make the car run properly...

I highly highly recommend you get some form of engine management. The turboback is a great modification for horsepower, but without EM you might get some screwy OL/CL issues. Boost controllers are also notorious for killing engines without a good professional tune. My suggestion would be to find a local tuner who has a good reputation with engine tuning, and knows how to work with ECUTEK, get it professionally tuned.

i'm not exactly sure as to what ecutek is... is that pretty much the same as turbo xs' engine management?? cuz that runs for about $900, then to get it tuned runs about another $300-$400. i only increased the boost on my controller 3 psi,and i emailed someone from cobb tuning and they said their access port isn't compatible with the boost controller, and if i get rid of the boost controller an buy the ap, then i'm still going to have around the same power as now... can't spend $1300, its not in the funds

Uncle Scotty said it best. That's pretty much the sound you're going to hear if you keep boosting above stock psi without EM.

yes well, you can get a utec as well, or an ECUTEK, it all depends on your needs and what you plan to do with the car.

ECUTEK is basically a license, it allows professional tuners to use ECUTEK to tune your car. Costs around $500, allow $300-$400 for tuning. Of course it's a professional tune, so if they know what they're doing, they'll adjust the ECU so that it will run as efficiently as it can, as well as drawing out the most power from your modifications. Unfortunately you cannot tune ECUTEK yourself if you wanted to.

TurboXS Utec is something you install into your ECU. You can use a laptop to tune it yourself, or get a professional to tune it for you. There's also this nifty device you can purchase that will switch between the 'low boost' and 'high boost' mode that makes it popular. Set it to low boost on the daily drive to save gas, flick that switch to 'high boost' at the racetracks and you're ready to go.

Both have their pros and cons, it's up to you to decide which is better. UTEC has the most flexibility because it allows the owner or the professional tuner to do the work, and you can switch between ECU settings. Of course this is the most expensive option as well, costing a total of $1200-$1300 for the cost of UTEC and tuning. Of course if you know how to tune the car yourself, UTEC would be your choice. ECUTEK is cheaper, and still allows a professional to tune your car, in case you're the 'hands off' kind of guy. Of course if you constantly go engine modifications, you'll need to pay constant money to get it constantly tuned.

My personal preference is ECUTEK.

You seriously need engine management, it's now a necessary thing since you increased the boost. You should set the boost at its stock settings and keep it there until you do get the funds for EM. Tuners everywhere have horror stories about how boost controllers have killed engines, and then the owners of the car blame the car for being 'poorly made'. The increase in boost increases the amount of air flowing into your car, which is great, unfortunately the fuel injectors are still shooting the same amount of fuel they normally would. This results in your engine running lean, which is death to any engine, ESPECIALLY a turbocharged one. Even running 1 psi over the stock limits without EM will eventually lead to a killed motor.

Well, I hope by now that you plan on getting EM, I would hate to see you prematurely break the car because of that nasty boost controller. With EM a tuner can adjust the ECU to work with the boost controller, so that way it will work for you.

Then you better pull that stuff off your car. When it goes, you will be spending it, or walking a lot.

Not worth it unless you have tons of money lying around to fix your car. If you "aint" paul walker dawg, i suggest you get long term power modifications like engine management, well thought out stage upgrades, etc. etc.

Accessport is my next choice in upgrade, it's affordable and very flexible. UTEC is basically a programmable unichip and it's almost universal that normal folk can't program it right. When Worldone had a proffesional tuner come to the NW he noted that ~90% of the amateur tunes were complete junk.

The off-the-shelf maps aren't considered as safe as a professional tune, and you probably won't net as much power from the engine as you could. AP ProTuner is an excellent choice....however the cost of AP+ProTuner is $1,000, you might as WELL get the UTEC if you're spending that much.

And yes I agree, the vast majority of amateurs don't know how to properly tune, WHICH is why I'm going to let my local (and highly respected and trustworthy) tuner do the work. Plus the guy who's going to tune it works for a large aftermarket company that works very closely with Subaru...so yay.

that's pretty funny. no doubt true.

when i take a peek at professional tunes, ~50% of them are complete junk, so i agree.
