[5.0 smoke em]

im running a 91 lx stock 302 with full exhaust. i was wondering what all i would need to be done to make sure i could put 100-150 shot of the giggle gas. me and my friends normally run a small road that is probably 1/8 mile and i was a little quicker time.

First, take your car to the track. Thats the only place you'd be able to dial in ANY amount of Nitrous the right way, other than a chassis dyno.

What do you need to do? Best thing you SHOULD do, is research as much as you can about every available kit or system available for your car. It would be a good idea to educate yourself about Nitrous in general, so you dont make the common mistakes. The stock engine will take up to a 150 in most cases. I would limit yourself to a 75-100 to keep things safe, especially seeings as you probably wont go to the track like you should.

you could fit a 200 shot safely if its tuned right. without a proper tune no nitrous is safe. usually guys that are losing there nitrous vcard start off with 100-125. you wouldnt need to really do anything to make sure you could put it on, just make sure the tune on it is right.

You cant run 200 without stepping up to a bigger fuel pump and changing the FPR and injectors. A wet shot at 175-200 is POSSIBLE.. but i wouldnt chance a wet shot again, ive lost alot of intakes and hoods running a wet shot at that power level.

The best way to start with Nitrous, is to start SMALL, and work your way up. Patience goes along way with squeeze.

oh gosh yea duh, i thought changing the fuel system was a given on any shot of nitrous... i would never run nitrous without beefing the fuel system.

Huh? Ive run all the way up to a 150 dry shot, with a BONE stock 5.0 and fuel system. My A/F ratios were slighty discomforting, but its definately doable. With 100hp, you can run all day long, so long as you pull your timing (or run supporting fuel) and keep your revs down. Lots of people run Nitrous with stock fuel systems. Im saying you cant do that with 200hp, no matter how its tuned.

[superman5.0]

yea im sure its safe to do with a stock fuel system but if i were to put nitrous on a car i would do the system first. my kit with 150 jets is in the garage for about 6 months just waiting and my fuel system is all set up to run maybe a 250 shot safely, if only the block could take it....

[Goblin]

Well i dont blame you. Im most certianly not saying you cant or shouldnt upgrade your fuel system. Im just pointing out you dont really need to with such a small amount of Nitrous.

[5.0 smoke em]

well when i do put the spray on i want it to be as safe as possible because i dont need any damage. so im thinking 75-100 dry with fuel system upgrades? what all do yall suggest to be done to tha full system?

[e3sean]

255 fuel pump 24lb injectors

[airforcesvt1]

personally id just get a wet nitrous kit that adds ur fuel to the mix.. then if anything u woul dneed a better pump! but for 100hp more.. i bet my belt buckle u would be safe on the stock pump..

however make sure you put the proper jets in and get on a wideband to see where your a/f ratio is at while onthe gas, then change jets accordingly..

tats the only advice i can give you on a shot like that..

there is more info i can give but that pretty much sums it up!!

i have a wet shot on a fairly stock 302, 75hp its a sniper nitrous kit(wet) made by "NOS" i run it all the time and its great

Put a 255lph intake pump in for piece of mind. Leave everything else alone. Spray away. A stock 5 liter will handle 150 hp without flinching. I think the limit on most dry systems is 150hp. I've never seen a dry kit rated for more than 150hp anyway. If you get a wet kit make sure it is a plate kit that goes between the upper and lower sections of the intake. All of the other EFI wet kits are accidents waiting for a place to happen.

The adjustable fuel pressure regulator helps but 24lb injectors are not necessary.

Dry is the way to go with EFI and a street car. I would suggest a system from NX. If you speak with the guys at NX, they can provide all the accessories you'll need to keep things safe.

Dont waste your time with WET single nozzle systems, or mini plates that sandwich between the throttle body and intake. Ive had some unfortunate accidents with both types, and it wasnt due to in-experience of lack of proper tuning. Its just the flaws in the design, and a poor concept of Nitrous/Fuel delivery. The only safe WET systems for EFI are the ones that sandwich between the upper and lower intake, just as Darrell said ^^
