Not trying to be rude, but if your a scooby specialist shouldn't you know the answer to your own question? But the answer to that question is yes.

I think he's looking for feedback from people who are running it, not wondering literally if anyone does it.



Anyway, Jimmy, if you'll help me pull my motor when it's time for the crawford block, I'll spray mine and we can see what happens

Jim. I ran a NOS brand import kit on my current 2.5 block. My bottom end is a stock USDM STI block that I got early in 04 which means is the weaker of the 2.5's.

I had typical 50 shot jetting installed since I had a 2.0 before this 2.5 motor. The 50 just did not have the kick it did on the 2.0. Jetting was 22 fuel and 37 nitrous from memory. After messing around with it I called NOS techline and learned a few obvious things. A 50 shot on a 2.0 which on my car produced 50-60whp will not produce that much power on the larger engine. More like 35whp according to what tech support said. I was given new jet sizes for the 50 shot. Which at this time I cannot remember. Those where pretty fun. Then I jetted up to 90shot. I ran it on the dyno with a GT30R based turbo. It produced 90-100whp before the clutch let out around 420whp. I also taxed out the Single walbro pump once the Nitrous came on.

Nitrous is great fun and its cheap. If you take the time to install the kit right and learn how to tune it you will be fine. I would not think about using NOS with out a Good EGT gauge, AFR meter and a Knock link. The knock link is a must. If you hit the button and it dances you know to let out. EGT helps you from melting the motor. lol... It also helps to tune the Fuel jet and lets you know when to let out. Its a duty cycle thing with nitrous. You cant just hold the button down for long periods of time. I left the 90 shot jetting in there on my current GT35R 700hp turbo. I plan on using to to spool up and cut off at 18 psi or so. If I can answer any questions about what kit to get or anything else Email me or call me up.

how much would a single wet fogger, like the one you described to me, cost? and where does a wet system input the nitrous?

hmm, so my understanding is..

running a 50 wet shot on a 2.5L isnt quite that effective, im sure it gives some boost of power.

green + nitrous+ race gas, i bet that gives a pretty mean combo.. but then again, no one has done it yet..

Nitrous Kits are much more reliable than Alcohol injection kits, when setup properly. I can't tell you how many alcohol pumps I've seen fail at the wrong time. Most of the alcohol pumps aren't designed to run alcohol so their bearings and seals go early.

Clark has the right idea, though I preffer the NX brand as the solenoids are built a bit better. Either kits can yield great results!

Nitrous is Cheap and can be controled in so many different fashions, you can customize it to any application. So many people are afraid to use it because they DO NOT KNOW HOW to use it. A Single fogger Wetkit ( or dry depending on EMS) is great to get those laggy turbos flowing, while a direct port provides for great equal distribution to take advantage of a full nitrous assisted motor.

And for those who think bottles are for babies;
Power is Power, doesn't matter where you get it from! There are no excuses for the results at the end of the track!
