somebody talk to me about a zex dry kit
OK I just got a zex dry shot (was told 75 shot) for free, I have never fucked with nitrous or wanted it so I've never read up on it. Should I spray my type r swap in my hatch for now since it was free? What else should I do to this bitch, plugs, retard timing, bigger fuel pump? It will be a bit before this thing gets built/boost so I thought this might be fun for now :1

Re: somebody talk to me about a zex dry kit
Retard ignition 3 degrees, as well.
Spray your first couple of times on a full bottle that you heated up (in a bathtub, hehe) until the safety valve pops to let you know the pressure is at the highest it'll ever be and the car will run the leanest it will ever run. After you spray, check your plugs to make sure the engine likes it. This way there is no chance of you thinking the setup is fine and then getting a higher bottle pressure that leans you into the danger zone. Seriously, though? Most of those kits are jetted for safety and you'll run super rich. Unless an idiot has fiddled the jets she'll work sweet out of the box on a 75 shot. ;) |

I was hoping you'd show up JD.

Re: somebody talk to me about a zex dry kit
Oops, sorry.
You get pressure applied to the FPR with a dry kit, so the fuel pump spikes in pressure and provides extra fuel. Less reliable, but it being a smaller shot you're probably fine. |
Re: somebody talk to me about a zex dry kit
fpr adjustable raise the pressure up
the zex 75 shot actually runs pretty lean at stock fuel pressure. Melted a couple spark plugs . Moved up to 60 psi on stock ecu and the car took it like a 19 year old coke ----- |
Re: somebody talk to me about a zex dry kit
we ran a ZEX dry 75 shot on my buddys d16z6 went threw 6 bottles before the ringlands went. this was back in the day before i knew any better, with plugs and a little less timming u should be fine :6

that and the adjustable fpr. The high fuel pressure before the nitrous is money never failed . Also ran wet kits that way has well. Just run it rich black smoke is your friend |

colder plugs with nitrous is mando stock heat range melt. 3 degrees retarded isnt much and will not make a car run that bad especially when your getting 65+whp to the ground |
Re: somebody talk to me about a zex dry kit
Thanks guys, Its too bad its not a wet kit but whatever I'll give her a go. O0

You can get one of the double-sized 29C512 or 27SF512's and burn two .bins to them, flip a switch to arm the nitrous and select between the programs. :) |

rawr, I have a link for you when I'm not on the phone. highroller, there's a reason ppl put up with my neurotic ass.

Re: somebody talk to me about a zex dry kit
If you want cold plugs, I always hear Bone say Mustang ones.

the dry kit is a nice unit has well. Trust me about the adjustable fpr on the zex dry kit never damaged a motor with that set up or do what jd is saying and have a bin set up with some extra fuel when your on the bottle |
Re: somebody talk to me about a zex dry kit
ill give you my .02 since i have used that almost exact setup
JDM B18C (GSR) with a 100 shot dry zex kit. retarded the timing 1 degree. BKR7E's (part no. 6097) gapped to about .028/.030. took that ---- like a champ 12.7@112 on MT 20x8's in a gutted crx. i had a walbro 255 though so im not sure how much the stock pump will take a 100 shot. i believe i used the 43 nitrous jet and 29 fuel jet. make sure you use thick wall vacuum line and strong zip ties for the fuel vacuum hook up becuase it actually uses nitrous to raise the fuel pressure, not actual manifold vacuum and i had the line pop off twice and actually split once. luckily when that happens the box shuts the nitrous down so you dont grenade the motor from lack of fuel. |

Re: somebody talk to me about a zex dry kit
stock injectors will not hold a 75 dry shot safely even with a 255 LPH HP Walbro.
R5671A-7 plugs, -8's when running 85-100 shot. 75 shot = timing at 14 BTDC, 85-100 shot = 12 BTDC, I was running 87 octane even. 75 shot melted a piston from a lean condition, ford 30 lb/hr red tops cured that. Look at the ground strap and carbon on the heats for heat range accessment when spraying, also the dry nozzle should be 18" from the TB, like at the RF frame rail. |

Re: somebody talk to me about a zex dry kit
it seems to be different for every manufacturer. i think corey was using NX jets.

Re: somebody talk to me about a zex dry kit
alright now you guys are getting me stressed, bone are we talking about a zex kit with the pressure on the regulator to raise the fuel pressure?
Chris what does a adjustable regulator do that a stocker doesnt? I'm guessing you crank up the fuel pressure all the time (not just spraying)? |

My buddy ran a 75 shot on his d15b vtec on a stock ecu for ever. The car with the stock fpr was melting plugs cranked base fuel to 60 psi and the bitch took it and ran forever over 2 years before switching to boost. When I blew my motor I ended up throwing that motor in my car for awhile to motor still ran strong after god knows how many bottles Fuel pressure is your friend. |

i'de love to pick up a cheap nitrous kit to run in the wagon for shits and giggles

the jet in it is a 35, is that 75 hp?

Re: somebody talk to me about a zex dry kit
How are you guys talking about fuel and nitrous jets if its a dry shot. ???
|
Re: somebody talk to me about a zex dry kit
It has a fuel jet to meter bottle pressure into the FPR line to jack fuel pressure.

Re: somebody talk to me about a zex dry kit
were is it located?

Re: somebody talk to me about a zex dry kit
From ZEX catalog (got a comp cams goody bag yesterday!)
EFI Dry 4cy 55 = 36F/32N 65 = 34F/35N 75 = 32F/38N 100 = 26F/46N Me...... 85 = 28F/40N 100 = 28F/43N Going below 28F jet does no good, once the FP regulator is clamped off, fuel pressure not going any higher. Yes, I used NX jets also......part of the info I provided 6 years ago. (damn it's been that long?) |
Re: somebody talk to me about a zex dry kit
okay since were talking about the zex kit i have a question. since the zex kit has the clunky control box, is there anywhere i would be able to hide it so that it's out of sight? with my old car i would have tried to mount it to the inside of the firewall since there wasn't any heater or vent ducting but the wagon has all that and i'm not sure if it would fit or how far it coudl be away from the vacuum source. any ideas?
