i am thinking about Nitrous on my 84 Z28... it has 350 mostly stock... 150 horse shot is just about right i am thinking.. what upgrades should i make??? by the way... i am running a holley 650 carb.... should i move to a bigger carb???? thanks guys...

 

someone has to have an answer!!! please help... all i have been able to find is stuff for tpi cars... there are those of us who still have carb's... please someone... i'm looking to buy in acouple of months...

 

I'm no nitrous expert but I am sure someone who is would say watch your fuel pressure. Make sure it in good working order and dont let your car run lean or you'll blow it up. Might want a fuel pressure regulator and/or safety switch that will watch your fuel pressure for you. I'm sure if you look you can find stuff by searching this site, just gotta read alot.

 

you wont need a bigger carb if you run a wet system. if you choose a dry system you might need to jet it a bit on the rich side to prevent from melting a piston. good luck

 

carb is a tricky area....at least for me i have no idea as fuel injection on the tpi is so much easier to deal with.

i can tell you this though which i'm sure is universal. 150 is pushing the limits of a stock block......you'll run but the question for how long is inevitable.

running more than a 75 shot i would definately recommend, which you should do anyway, your fuel system; this would include a
new stronger in tank pump, booster pump, basically all the things you will need to get high fuel flow.

fuel is the most important thing to keeping you safe, run rich and you only run the chance of fowling plugs.......run lean even one time and take the chance of blowing something up.

i would assume you'll probably need things like a fuel safety switch and such; but again i know nothing about carbs.

to get mine to work on fuel injection here's a basic list:

N2O kit itself
N2O pressure guages.
air/fuel ratio guage.
electric fuel pressure guage.
tunning using a wideband.
new intank fuel pump.
booster pump.
highflow fuel filter.
rpm window switch.
fuel safety shut off switch.
adjustable fuel pressure regulator.
all the switches, wiring, braided line, and other necessary hook-up equipment.

i know there are a few more things that i'm forgetting but you get the idea. it isn't just bolt on and go. you can seriously screw things up fast as well as hurt yourself if your an idiot driver. (no flame towards you of course)

 

150 shot is pushing the limits of those stock cast pistons.
ANY detonation and things will get ugly.
I seriously recommend you purchase a nitrous tuning book (there is a good one in summit) and 99% of your questions will be answered. you will understand exactly how nitrous works. what to do and what not to do.

for $20 you could save yourself a blown up engine, and you will have a better idea of where to start.

good luck :rockon:
