I use nitrous on my 98GT and check out my sweet times I ran on a 75 shot. (check the sig)

 

well it is funny u said that because when me and some friends were at test n tune on thursday night my friend cracked his on his 98 GT but he replaced it with a crown vic manifold i believe, not all plastic. He was basicly stock and was not runing nitrous

 

I've replaced bad units on both 98 and older and 99 and newer. i never really see a crack, more of a seperation at the joining of the two molds.

 

I would imagine that if they are prone to cracking then the thermal shock of a large spray of nitrous could increase the chance of it happening.

Plastic manifolds . . . .

 

the old ones crack because they werent thick enough..... they were recalled.. so it is a free fix



as far as everything else .... i wouldnt do the timing adjuster,.... instead get a jms chip and they can not only adjust the timing but the air fuel ratios as well ......


and as far as nitrous backfires,... if the bottle pressure is ok and you use a window switch you shouldnt have any problems!


just make sure to have someone who knows what theyre doing check everything if your not sure about it.....(better to ask a stupid question than to make a stupid mistake)

 

will the jms chip allow you to switch your fuel/timing settings for an N/A run vs a NOS run? Those were my thoughts for the timing at least with the timing adjuster.

 

Horror stories galore:o

I think Ive ran nitrous the most on this site on a mod motor(if not close anyways).
I had a 98 gt with every bolt-on known to man for it.
Headers,off road Hpipe,Dumps,355,then a 410gear,Timing adj,70mm TB,80mm Mass-air,Pullies,70-30 struts,no sway bars(anywhere),shifter,Manual fan switch,Screamin Demon Coil packs,LCA's,Eibach Drag Springs,and Juice.............
Then after a couple of years put 2001 P&Pd heads and intake:o
That was like adding Juice again
You will want too get the NOS Kit for your 2002 I cant remember the part number but this is what it comes with(If the kit your buying doesnt have all of this in it then dont get it):
1. Window switch with 3000&6000rpm pills in it.
2. Fuel safety switch
3. Bottle
4. All the wiring(ties in with your Throttle Sensor)
5. Bottle (of course)and Nitrous lines,Solinoids
6. Arming switch
Think that is it 1,2 are very important and should not be left out!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I left out the window switch on my old car at it bite me in the axx.
But still ran a 12.4@112 without a piece of my piston:o .
If you get a Wet kit then youll be installing an intake its not when it how many?
The Nozzle kit from NOS is the best of the best in my opinion but is pricey but you get what you pay for and it install so that all the Nitrous and fuel goe in your engine instead of anything through your intake.
Dont go over a 100 shot(125 isnt going to make you that much faster just make you closer to making a mistake)this will put you in the best performance/safty margin for your car then work on stuff like suspension,lose weight(your car not you)Good tires,if you have an auto get a stall convertor,Lt headers......Everything adds up at the track or should I say subtracts(within reason).
Nos Kits come pretty safe if you do what they tell you.Once you get your engine mods done then you want more go get it tuned!!
If you stay with a 100 shot dont worry about timing but just to be safe if your going to beat on it get a gal. or two of 100 octane race fuel for an extra safty eature if you do this your car should be fine for a long time.I ran a 125 shot on my GT for 3yrs safely then I got greedy and it cost me so your lesson of the day dont get greedy and youll be happy for a long time there is nothing better than hit the gas and feeling an extra 100 HP hit you where it counts

yeah... you can have one setting for all motor with advanced timing and leaner a/f's and another with retarded timing and rich a/f's


but dont mix the adjustments when using the bottle or BOOM!
