Alright, I'm a complete Noob to Nitrous.
Now that that's done with let's get to what I need help with. Anyways, My girlfriend just ordered me the HSW kit for 334. That's my xmas gift. Now, I know what I have to buy is a purge for it, a recommended bottle heater, window switch.
Now I believe those are what I need, if anything else let me know.
Now, fuel questions. I have a G5x2 cammed LS1, with stock heads. I have stock injectors, so what is a good size injector to buy.
Also, will the stock fuel pump handle this?
Any other advice let me know, I'm not trying to make my motor go BOOM

Well what is this kit rated for hp wise? Your current fuel setup should be good if you only spray 75-100 shot. If I were you I would get some TR6 spark plugs to go with the kit though.
To address your other questions, any of the vendors will have great bottle heaters with real competative prices and sometimes they have specials. So look for them.
Remember that whatever purge system you decide to get (all are good systems), they don't include the tubing which exits the car. And if they do the tubing is so short that it doesn't really help. You can do some searching to help you out once you get a purge kit. Not a big deal, we all had to deal with it.
I have only dealt with nitro dave as a local vendor and he was very very helpful. He made sure I got what I needed and helped me in everyway he could. I hear that most of the vendors here are that way, but Dave is who I dealt with and I can only speak from my experience. Good luck!

Thanks for the response. Now that you mention it I do remember recommended to run a different spark plug with the nitrous. Good advice on the purge information. Much apreciated. I was looking at spraying 125, I guess I'll wait for a vendor to pop in and help me out further
I put autolite 103's in after buying the same kit, they were gapped good right out of the box, all of them were at .36. Do you think that you would need the timing tuner? Matt@HSW was very helpful and did not hesitate to answer any questions and he did so in a timely manner.

Thanks for the info guys. I think I probably will upgrade the fuel pump. Why do it, unless it's done right. So I'm looking at an upgraded fuel pump, 42# injectors, bottle heater, purge, window switch, and anything else you would recommend
Sounds like you got a GREAT girlfriend!
Is the system wet or dry? If it is wet injectors should not be needed.
While 98SS1LWEE may get back to you in a week, just because he can does not mean you can (especially with your mods).
I recommend jetting small (start 50 then /75/100/125/150) testing on a dyno or with a Wideband on the street and working your way up methodically, keeping the AFR under 12.0.
Had I put 100-125 jets in my vette (totally stock) I may have been in some trouble as with a mere 75 shot on Dry, my AFR was in the 13's. We did a 50 shot on mine which was nice and sweet @ 11.5 then a 75 shot. The 75 was very lean. Yet Todd can spray a 125 with no problem (we have similiar setups with different nozzle positions). Bigger injectors solved my problem, but had I bought into the "everyone can spray a 100-125 no problem", I mighta been in a bind, I am very glad I listened to the advice I got from those when I did my install on testing.
Since your getting your base kit from Matt, give him first shot at the other items...then if you don't like what Matt has look at the other vendors such as DynoTune, Nitrous Outlet, or Nitrous Direct.

I have a wet shot on order, I still need injectors either way as mine at the duty cycle were 95% and dumped fuel at 5500 rpms, so I guess if I'm going to upgrade why not just go 42lb's right. As for the pump, is it a definite that I would need it. I would like to be as safe as possible with spray as I'm scared to do it, but love the rewards of it.

Maybe someone who is more educated in this are can chime in?????

edit: I just read that you have a wet kit coming. With that being said, I think the feul pump isn't as necessary! However a good idea none the less. JMO though!

On the fuel pump, some cut a access hole in the floor to get to pump, then put the piece back and carpet over and no ones the wiser.

Yes, the "trap door method". You can find many writeups and pictures on how to replace your pump without dropping the tank. Just have to decide if you want to cut a hole in your car or not.
I'm in the same boat as you z28C4maro82z. My girlfriend is gonna buy me a Nitrous kit also for Christmas but I don't know what I need, lol. I wanna spray a 75 or 100 shot. I'm thinking I should do a wet setup because I won't need new injectors. But then it doesn't make sense why anyone would do a dry setup? Steve <----totally lost, lol.

People do dry setups normally as a dual stage. At least to my knowledge (which isn't too extensive) What I have seen done is run the dry stage first then the wet next.
We have good girlfriends I think
, they are certainly keepers.
We have good girlfriends I think
, they are certainly keepers. Sorry, didn't see this post until just now. All of our kits are rates at the rear wheels, so the jetting is RWHP numbers. Since you do have a cam I highly suggest a fuel pump upgrade, the Racetronix kits that we carry are nice as they are complete plug and play kits. Another option would be one of our stand alone fuel cells. That would allow you to run a higher octane fuel in it and would support more HP then a single in tank pump. Since you are running no need for the fuel injectors, as long as you are goon NA that is. Now if you were stock or just had some bolt ons you could spray a 150 shot on the stock fuel system with a wet kit or a 100 - 125 dry shot depending on what size injectors your vehicle came with.
Let me know if you guys have any questions with anything.
Thanks,
Matt
