I have an 01 A4 z28 with exhaust and lid...i Just bot a NOS wet kit..im wanting to run 100 shot on it...now since its wet i dont need to upgrade my injectors right??But i need to upgrade my plugs and get a good tune before i spray,right???

 

also what kind of plugs does everyone reccomend and what are the prices...from what everyone has told me i need copper plugs and NGK is a good brand so im leaning toward that..any specifics would help!!

 

NGK tr6's.
as long as the car is running well, and generally healthy you shouldn't need a tune.
injectors will be fine.
do you have a window switch??

 

I'll agree. And gap them around .035

 

No need to tune, especially with just exhaust and lid...

You're correct that injectors won't need changing because the kit is wet, but your fuel system is having to supply extra fuel regardless, so be sure that your pump is capable and, depending on mileage, you might want to replace your filter.

As far as plugs go, the NGK's are good, but remember- no matter how much everyone loves them, NGK didn't really have nitrous use in mind when they made these plugs. ZEX makes a Nitrous specific plug that you might want to look into. Although I've heard mixed reviews, I've used the plugs myself on both nitrous and turbo applications and have never had a problem. I'd recommend them.

I hope you do, because if you don't, only bad things will come of it... Don't skimp on this. I promise, you'll be glad you didn't in the long run. Unless, of course, you don't mind purchasing a new LS1...

 

I have always ran NGK Tr6's with my nitrous set ups and never had a problem.

 

Yeah, I've never really heard of anyone having a problem with them either...

However, the Zex's have a triple electrode tip that dispurses the spark more generously which is definitely a plus with high horsepower nitrous applications.

I'm a fan of the "Better to be safe than sorry" philosophy, but hey, if you want to save a few bucks, spring for the NGK's.

 

NGK TR6's are good, or some people run the Autolite 103's. As was already stated, gap them at .035". I also highly recommend a window switch. The stock fuel system is generally good up to 500-550rwhp, and with your current mods plus the nitrous you should still be ok with it. If you plan on doing more mods in the near future you might as well add either a fuel pump or a stand alone fuel system to your list.

 

im not sure if i have the window switch or no...im new to the nitrous game..what does the window switch do..i know i have a micro switch and full throttle switch

 

The window switch works in conjunction with the wide open throttle switch and only allows the system to operate within an rpm range that you can adjust (3000-6000rpm or what ever you want). It will either by digital or analog. The analog ones use little rpm chips that plug into a small box, while the digitial ones will look basically the same but without the plug-in space for the chips. The boxes are generally about 2-3in. square.

 

how much is a window switch??
i have the fuel safety switch...that just kills the nitrous if sumthing goes wrong...right??

 

Yes . And a window switch can be had for around 100 bucks check out some of the sponsers.

 

also how nasty is this thing gonna be on street tires...if im goin from a roll where should i spray at and if im goin from a roll should i just spray right off the bat???

 

If you do use a window switch that will be built into it. Or I hold it in second and arm it then when it goes to wot it sprays on its own on a wot switch.
