nitrous on an 03 g35
how many people have it? I have a 2 stage kit for my camaro z28, but it's too much of a setup for a g35 smallest nozzles I have for even one stage of it 150 shot. I am thinking about building a kit for my g35 using mostly stuff I have and getting some custom nozzles, a bigger fuel pump, and some new colder spark plugs.
How big of a shot are some of you running? I read that 420 rwhp was fairly safe on an FI g35. I was thinking that a 100 shot would be safe because of that. maybe a 125 shot.
parts I already have:
oversized fuel solenoid from harris speed works
oversized nitrous solenoid from harris speed works
harris speed works microedge
blow down
generic purge kit
40ft of braided nitrous hoses ( was cheaper bought this way. and I was planning on doing more than just 1 bottle in the camaro...)
seperate fuel system designed for f-body with fuel cell and seperate fuel pump ( might modify to work, but probably not)
bottle warmer for up to 12lb bottle.
wideband o2 sensor for lean condition cutoff
big question I have is how to get the tps sensor to work with the drive by wire on these cars.
any other info from someone who already did this though would be appreciated.

I'm actually surprised there aren't more people into nitrous on the g35 though. there are plenty of nitrous'd 350z's out there pulling cobra's on 100 shots. I am going to be opening a similar thread on my350z looking for someone with experience on the vq35de with nitrous. My experience personally is limited to a trd camry(50 shot), a friend's celica (custom 80 shot on home made kit), tiburon with 100 shot(blew up spraying off the line at the drag strip spraying from 2300rpm, left him with only a block he could use), and my camaro which was sprayed with a 125 shot and never had a problem related to nitrous, but blew a head gasket because of bad gas. ( paid for premium and the octane was no where near 93. only got 10 miles down the road before it started pinging and then by the time I got off the road the head gasket was leaking water). I just don't have experience with a vq35de on nitrous. I am wanting to do it though. I already have the majority of what I need for it. Just need to figure out a few things first.

I know it will decrease the life of the motor just like running a supercharger or turbo would. for me though, I like the feel of the instant power from nitrous.

I know what you mean. It's addicting. But this VQ35 is not a cast iron block 350 with a 9.5:1 compression ratio. These things are tuned within an inch of there lives as it is, they have a 10.5:1 comp ratio and I think the new ones are over 11. I wanted to do the same with mine, but using it as a daily driver, common sense won out over the head rush.

BTW is this car a 6 spd or the 5AT??
ive been thinking about spraying a 100 shot for quite a while now. im at 60k miles and i think if you get it tuned on spray for at least one setup ( assuming you get osiris and choice of a few different maps) and i assume you would be fine to spray. i mean just be sensible and spray when you are running someone or at the track. don't just spray on the way to dinner to impress your girl

isnt high compression better for your nitrous as well as all motor setups?!?

what does psi have to do with nitrous? jw and im almost positive high compression is better for this setup. would love somebody to confirm whether it is high or low compression that is better
you're stock psi on most turbo kits as well as wastegaste springs are usually around 7-10 psi. so how the f&*K would waste all that money to ride around on only 5 pounds. maybe its about how you tune the car and how long you actually expect it to last... stock rods aren't good past 450 so when talking reliably i wouldn't push a car with 350 and stock rods and not expect a bad outcome. now if i had rods able to hold 600 and pistons just cause we were doing rods then i would feel pretty comfortable.
. but once again this is about nitrous and not turbo so totally different subject but non the less simple pistons and rods, upgraded head gasket and possibly block gaurd, plus a tune and i would spray the hell outta my vq, and actually plan to here soon

turbos and superchargers ram in air and mixed with fuel at the right amount
and with the spark timed correctly... create more cylinder pressure therefore
more torque.
NOS does it a little differently but the outcome is the same... cylinder pressure.
X amount of torque is the result of cylinder pressure
I think what the guys are trying to say is... the stock setup (heads) wont
stand a lot of cylinder pressure, not boost pressure.
perhaps switching to a better gasket and or "O" ringed cylinders and studs
instead of head bolts (not familiar with the stock setup as it may already
be studs) would help with the head problems
keep in mind that 5 psig of properly inter cooled, fueled, and sparked boost
with a compressor that is sitting in a high efficiency zone will output more
power than the average 7 to 10 psig of hot air and crappy tune... I've seen
this way too often.
