Turbos are great but i am going for the bang for the buck. I would like to know if NOS or any other nitrous companies make a system for the Impreza. Nothin major, just enough to surprise some stangs and occasional camaro. Thanx

up, anyone know? im interested too

Go PM Kevin Thomas... I think that's his name... yeah...

he has a turboed AND Nos'd OBS...

Venom? is borrowing someone's RS I believe.

i have on for sale......has some goodies with it.....drop me a email i will give you mroe infor on monday when i get back for my vacation..

thanks,
space

I can't find Kevin Thomas's PM. I'm concidering a shot of "juice". I just don't know who makes a good kit.

All the major companies...NOS, Nitrous Works, Express, Venom, Zex, make universal kits that will work with any engine. Many people, including me, are hesistant to juice their RS, as it is believed the best way to take advantage of the Boxer's qualities is thru a snail. Am I right? Anyone? If you wanted to use chemicals to enhance power then go to a pro nitrous mechanic. Someone who gurantees his quality workmanship. Let me know the results.

I don't really want to use a universal kit anyway. I want something designed for the RS, not something that could be use on any Mustang. Venom had a kit for Imprezas up to 95 (2.2L). I guess the only reason I am concidering NOS is it seems to be an inexpensive way of gaining hp.

Imprezinator in AZ had a kit on his car. I believe it was a 50 shot. He is removing it for a trubo. Give him an email and he can give you some tips. He was running in the 14's with it.

Yeah, I have the Nitrous Express "Sport Compact" kit ans it went in easy and works awesome. It came with jets for 50hp and 75hp but I stayed with the 50hp jets.

The nice thing about the NX kit is that it is a wet system (As opposed to dry). Don't buy a dry kit.

I found that with the 50hp jets, I didn't have to make any corrections with the S-AFC. There was no detonation (pinging).

I went from a best time of 16.0 off the bottle to a 14.70 juicing it! That's 1.3 second with only 50hp!

Any more questionos feel free to ask http://www.i-club.com/ubb-files/smile.gif

Venom is makeing one for the 2.5. was going to get it before i got the turbo. Its all computer conntroled. give them a call.

Again, I think the Venom is a Dry kit though. Dry=bad.

Eric

Low 13's to high 12's! Impossible bro. Hate to burst your bubble. To do that you would definetly need a new Clutch and a lot more horsepower than a 60hp shot. Without a bottle heater (600psi bottle pressure) I ran a best of 14.700 with a 50hp shot (wet system) and without Nitrous I ran a best of 16.01

Eric

I believe that the times Kevin listed are possible, the thing to remember is he also has a stage 1 turbo. Also installing a new clutch would be a little tricky for Kevin since he has an automatic. http://www.i-club.com/ubb-files/wink.gif

Cheez,

I have been using the NOS dry manifold setup for a while now. It is kit #5122, which is for my car in general. NOS has kits available for cars depending on their displacement so I take it a kit like mine for your car would be #5123 or something like that.

I have a 50, 60, and 70 shot jetting. I am currently using nthe 60 shot jetting without any problems to date. I would advise getting an air/fuel ratio gauge and/or an EGT gauge so you can monitor how your fuel mixture and how hot your engine is running. Also, I recommend getting a NOS pressure gauge and a bottle warmer to get the full performance from your kit. It comes with a host of safety features (That I can't name off the top of my head) and my engine compression has been within specs. I have been running the Nos allot over the last year and a half.

For more detailed questions, I suggest reading a NOS Faq: http://home.earthlink.net/~burntoast/nos.html

Or stop by their homepage: http://www.nosnitrous.com/

Talk to a NOS technician and they should be able to help you with most of your questions. It seems that using NOS on Subarus is a 'black art' on this board and not a lot of people have been using it. I don't blame them since using NOS has the potential to screw your engine up in a hurry. I have been using it happily for a while though.

Performance: Without NOS, I run around 15.7-16.2 in the 1/4 mile, depending on the weather and how cold it is out. With NOS, my best run was a 13.85 with times usually int he range of 13.9-14.1. I have no bottle warmer. Rallispec is installing my bottle warmer this upcoming Tuesday. Im hoping to crack into the low 13's, high 12's when the dragstrips open up again. Good luck with your purchase if you do get it. It'll get expensive once you keep using the NOS over and over again.

I couldn't tell you what makes a 'good' nitrous kit. I just know that mine works. It also helps if you have a shop that knows what they are doing install your kit. Rallispec installed my kit and it was their first NOS installation. Needless to say, I have allot of confidence in their work and it paid off. Since then, they have installed more kits from what I heard. Take Care!

Kevin does have a stage 1 plus he just recently put in an intercooler (i think) and he has an automatic not a stick. Check some past post of where he raced camaros and a civic.

Keep in mind Kevin has a turbo with all the trimmings, NOS, and a Level 10 modified auto tranny...(correct me if I am wrong) It's entirely possible. Good luck Kevin!

Oh, Turbo.. THan yes. I thought he was just running Nitrous. Sorry http://www.i-club.com/ubb-files/smile.gif

Eric

I e-mailed Venom about a month ago and they said they weren't making a computerized kit for the RS. Things could have changed though.

Imprezinator,

I just got my bottle warmer put in by RalliSpec yesterday. Holy shi*! You won't believe the difference it makes with a higher bottle pressure. I didn't expect much but it scared the *&#$ out of me. Actually, I think I damaged my tranny even further. You know that little tug you feel when you put your car into drive or reverse? Not anymore! Even driving out from a stop is a little hesitant. Oops!

Anyway, I didn't really get a chance to test it out yesterday since it started raining and snowing. There was this Prelude SH that attempted to pass me at full speed (Stickered and all) and I hit the button just as he got one car length ahead of me. All hell broke loose and the engine sounded a little to scary for me. I passed him so quick that he didn't bother to drive beside me after that. He simply stayed behind me the rest of the way. Lol! That was the second time I used it.

The first time I used it was what caught me off guard. I was driving to get my bottle filled and was just testing out how it felt from a roll. Usually I get a jolt from the turbo kicking in, hit the Nos and you would feel a long pull that seems to make the care accelerate a bit quicker. This wasn't the case after the bottle warmer. I had approximately 950-1000psi on the bottle gauge (vs 550-650psi that I usually have). I hit the button and the car took off so hard that I actuall ended up going over the double yellow line. No cars were in sight. I wouldn't have done this had cars been on that road. I never thought our cars could experience torque steer from a roll. I usually get this in first gear while using Nos. It was a little frightening and I don't like it when things seem to get out hand. Of course I'll do it again but on a track http://www.i-club.com/ubb-files/wink.gif

I changed my jetting back to .032 (vs .034 that I was using) and I'll be testing that sometime soon (Maybe this Thursday or Friday). The 50 shot (.032) never felt powerful at all but that's because I didn't have good bottle pressure of course. I dying to see what times I could pull at the track. Damn I want to hit 12's so bad before something breaks. Get that warmer man. It's feels like I just installed 30 more hp at least. L8Rs

Hope you get that tranny figured out. I can't wait for another impreza to pull into the 12's. Now, I am assuming you can define you car as "scary fast"? hehe

Wow! IT makes that much of a difference huh??? I'd get a bottle warmer but I don't think it will be worth the money since I have a turbo kit on order. I wish I would have known sooner! Thanks for the update http://www.i-club.com/ubb-files/smile.gif

Eric

The Venom kit puts more fuel to the motor by the computer it comes with. They say it makes the band wieth on the injectors longer. That would make it a wet sestem, right?

wrong.

A wet system taps into the fuel line and injects gas and nitrous alowing better atomization. Changing injector pulse is ok but it still has a higher margin for error than a wet system.

Look, I have the Nitrous Express wet system and have had no problems so why don't you just try something tried and true...

Eric

Thanks for the info. Dont think ill be adding it to my turbo rs. Even though kevin is doing it. makes me nervous.

13s with a 50 shot I believe it, I run 14.75 consistently witn no turbo & no nitrous

Niloc, What have you done to your car??? is that G-tech or real 1/4 mile runs??? Let me know the secret! I can only run 16.0's off the bottle.

Eric

Real 1/4 - West Hampton drag track
3' strait pipe no cat's
modified JC intake
custume cam & gear box
port & polished
PossumLink ECU
& a few other goodies, Got the unor. pulley put on to day so it back to the track next wed.

OK. That helps explain it. I thought it was without cam or intake/head porting. Wow. That's pretty good!

I'm thinking of having custom cams made. I have access to a person that makes camshafts for one of the best (NHRA) Top fuel teams. how cool would that be!

Eric

Imprezinator,

I didn't think it was worth it either. It's fairly cheap, easy to install (It looks like it anyway) and you probably can have it in 2-3 days. Who did you order the turbokit from? I hope it ain't JC. If you did, well, you'll be having a lot of fun a lot sooner. I'll be testing the smaller jetting tonight at an old airport against some other cars. I will be racing a old 'work truck' with a Doge V10 (ala Viper) engine in it. The truck runs 12.4's at Atco Raceway and it looks ridiculous. I know if I can hang with him than something must be working alright. http://www.i-club.com/ubb-files/smile.gif I may have to go back to the .034 jetting for this job. *gasp*

BTW: I noticed someone talking about Nos wet systems above and injector pulsewidths. I talked to a guy named Greg at Rallispec Monday while I was getting the warmer installed. I mentioned I had the 1997 2.5ltr Legacy GT ECU in my car and he said something about the 2.5ltr engines may have a different pulsewidth than a 2.2ltr engine, causing me to run a little richer than I normally would run. Is this true? Maybe that's why I haven't had problems with detonation and really lean runs. My SFC's highest setting is at 4% and that's at 5k-6k rpms. I wish I could test my stock ECU but unfortunately it was misplaced.

Fortunatly It isn't the JCSports group buy! I got in on a stage 2 kit from the LudeSpeed group buy. So far so good. Overtime put it together and has been very good about keeping us up to date. Good luck tonight!!!

Eric

I've considered a 50 shot just for friday and saturday nights http://www.i-club.com/ubb-files/biggrin.gif. I'm worried about nitrous belches though, since our engines do backfire occasionally. Have you had any trouble with this, Kevin? I figured if you did, we would have heard a LOT about it.(I saw you on the Car & Driver video clip. Congrats, you're famous http://www.i-club.com/ubb-files/biggrin.gif.) The kit will prolly go on after the ECU upgrade. That LINK kit looks more and more appealing.

Gary

Thanks burninrubber. And no, I haven't had any problems with Nos backfire.

I believe the backfiers we hear are through the exhaust. The only bad backfire would be through the TB and into the intake with N2O. With a 50 shot its not much of a concern, might make it to a filter and melt it. I have seen a 9 second camaro blow fire through a cowl induction hood and destroy the frount winshield though. It was like a 400 shot though.
