Ok. I just bought the zex dry kit and about to install it. I need some help with the wiring and the kook up of hoses. Some pics would help alot. I have XTC headers n downpipe on order and will get the Corsa touring in a few weeks. So, from what i've read and researched the stock 2.2 can handle 250 hp. so with the bolt ons i shud hav about 160-175ish hp(NOT TO THE WHEELS). and so i have a free area of just about 75. What basic stuff can be done to the engine just for safety. Like maybe an ARP sutd kit or something? I will have pics and vids of the install and when im done, so dont worry. Oh yea i'm also gettin a purge kit, maximizer kit, and the traction control window switch. I think the Zex dry kit will work fine, because of itz setup to work off the throttle and bottle pressure and hav a good fuel mix.

 

With a dry kit i wouldnt dare over a 50shot. Even with that dry shots still dont sit well with me. Get a WIDEBAND!!! You need to watch out so you dont lean that thing out.

 

Never do above a 50 shot with a dry kit

You will Lean out BAD and screw your engine BAD

 

I thought that the zex kit was made so that you can't run too lean? It comes with 3 flow jets(55, 65, and 75) Either way if thats the case then i'll just test with the 55 and work my way up to 65. Im not gonna try the 75, because im goin to hav the bolt ons. But any additional input would be nice.

 

KABOOM!!

good enough??

 

https://www.cobaltss.net/forums//forumdisplay.php?f=51 read read read, search, search, search!!!! please know that you should have bought a wet kit to begin with.. dry shot is VERY VERY BAD... and the cant design a kit that prevents leaning out to much if the system doesnt monitor the A/F (air/fuel ratio) and adjust accordingly you shouldnt even be spraying a dry kit & especially not over a 50shot, try just a 35shot. Please listen to us i dont want to see a "i blew up my 2.2 w/ a 75 dry shot" thread... just trust us, sell the kit, buy a wet kit & be safer.

 

your injectors more than likely won't be able to support enough fuel for such a large shot...if u wanna stick with the dry kit I'd be scared of a 50 shot.

 

i use to run with a dry kit but i changed over to a wet kit.. i know a bunch of ppl are afraid to run a wet kit cause they think the install is crazy hard but on our cars it's so simple the hardest part is finding a place to mount the switch... with a dry kit i would noit try to go above a 25 shot.. trust me

So if i were to sell the dry kit and purchase a wet kit, what power advantages do i have. Isn't wet just as potent, possibly even more than dry. I'm not gona buy the conversion kit, way too expensive, I will be more lucky in sellin the unused dry kit and puttin a lil extra for the wet. Thanks evry1.

 

noooo, wet kits are MUCH more safer than a dry kit

Theres no comparison

 

What if he were to use a set of ss s/c injectors? Those can provide more fuel than the stock 2.2 injectors.

 

The engine would have no way of knowing when the nitrous was being used

Plus the 2.2's cant be tuned anyway

 

so after reading this thread, ive concluded that a dry shot is bad...stay with wet. is that the same for every car, or just ours?

 

Dry shot = universally bad!

 

Okay i get the point, dry is bad, but will i be able to use the 75 shot of n2o nw, with the wet kit? Because i have a dyno a few miles from my house, so i was going to test and tune so that i don't get too close to 250, after i get my bolt-ons.

 

yes you will be able to run a 75 shot with the wet kit since you're pulling additional fuel from another source vs just the injectors which probably wont be able to provide enough fuel for the 75.

i would do as u say and sell the dry kit and buy the wet kit...u should be able to get a wet kit around $500-$550

 

it's not that hard to turn it into a wet kit.. just check out ebay for the contol box. you wont need the whole kit then just sell yours.. or do what i did and i bought each peice seperatly but from a site called dynotunenitrous.com..

Dry shot + FI + me being dumb= Boom, running on 3 plugs and getting towed over 60 miles and looking dumb in front of a girl I was trying to get with.

 

wet kit or no kit... period

 

Exactly. I am running a wet 75 shot with no problems.

 

So anyone with a 2.2 running a 75shot with mods? Caz dtz like pushing it to the limit of the engine isn't it? Caz i currently have an Ijen intake and im about to bolt on my headers and downpipe and, in a few weeks, my exhaust. Which all together is way more than stock, which they ran the n2o test on to show that 75shot is the most you can put on a stock engine.

 

Ok. has anyone who has been suggesting that dry kits are bad actually read up on the zex kit? it does do sum regulation by the bottle pressure so that it doesnt run to rich or lean. I've read that some1 on here ran a dry kit fine. So what is the actual, technical, bad part about the dry kit on our cars. I'm just curious.

 

you rely on your injectors to support the amount of fuel you need for the nitrous shot.

we have returnless systems so you cannot up the fuel pressure to comp for the small injectors...which I wouldn't really do anyway.

that is the technical part, not enough fuel = boom.

 

thanks man, appreciate the reply. that i understand. dry=boom, i dont understand.

 

ok here's what they are saying a dry kit only adds nitrous a wet kit adds both fuel and nitrous a dry kit can cause you engine to run lean AKA not enough fuel nitrous adds oxygen to your engine so by adding nitrous with out extra fuel it makes you air\fuel ratio lean a lean engine will blow you need to add fuel to compensate for the nitrous you stock computer wont do it so you have to do it some other way IE use a wet kit
