NO ! The plugs didnt cause you issue , the parts of the plugs that burned of because excessice high CYL temp didnt create hot spots and burn the piston , bad, poor or lack f tuning did

You can install 2 steps hotter plugs and it wouldnt cause you to burn a piston

You will NEVER find an iridium plug that is colder then the sp463 and why would you be using that crap with nitrous anyway

Plugs that are Irid or Plat and a few others in most cases are as hot or HOTTER then stock because they need the hotter temps to keep the trash burned off to run 100,000 miles

This is a little off topic, but what plugs do you recommend to run in the SVT with your tune?

[MajicBlurpleSVT]

most likely i was leaning out yes and thats what caused it but i know what i saw when i had the motor replaced and that was pieces of the plug melted into the piston and more holes forming from thoes pieces and that was B4 i started uping the fuel and retarding the timeing with the diff plugs and every thing has bin good for 5k doing it with the fuel+ and timeing -- with the itv27 denzo irid plugs and to get to the setup i run when useing the nos now i did use a friends wide band to set it up so i know im not running lean in all actuality im running way rich just dont have the money for my own wideband and he needed it for his car.

tom i know you know wayyyyy more than i do when it comes to things like this i was just letting him know he can do it for now untill he can get everything he needs

How do you know your timing is right ? How do you know your not bordering dangerous on your load , and many many other things . To say he can do it the way your getting by for now is just bad info and you shouldnt be telling people that it can be done that way

There is no doubt in my mind the parts from you plugs were stuck in your pistons for that to even happen your pistons had to be at the melting point for them to stick in the pistons

You need to loose those hotter plugs , get a wide band air fuel and some one to tune your car or you will be replacing another engine in time

So when I do the Nitrous I'll start with a 50 shot and work up to a 100 shot. I should be safe up to a 100 shot with a tune but dont recommend going higher with a stock motor?
I already have a wideband. I will be running a WET system with purge, bottle warmer, window switch, WOT switch, Fuel cut off switch, and a progressive controller. Also colder plugs?
What other type of components or gauges would you recommend.
Should I have a tune for each shot tell I get to 100?

you are also going to want to go one size larger on the fuel jet for the wet system. if it calls for a size 50 pill for fuel you use a size 51 pill. if it calls for a size 50 pill for nitrous you use a size 50 pill lol.
thats just a little extra something to help make sure you arent running lean during the tuning process

Thanks, picking up kit tomorrow

But it has a Throttle body plate?

[focusmaniaczx3]

huh? you mean a TB spacer that fits between the throttle body and the intake manifold? that is most likely so you can sticker her in there without having to drill a hole into your intake. ive been tinkering with the idea of making my own TB spacer for this purpose.

[KRYPTO]

yeah for the nitrous
