Well lately i've been doin a bit of research on various ZEX products.. I have a few questions for everyone if ya'll dont mind answering them..I've been thinking about buying a kit for my 5mge.. It's not a final decesion, i just want some info. if i do decide to go nitrous.

1. First of all, how many other forum members have experienced with any nitrous products? Please let me in on your personal experiences at the strip or on the street.

2. What kind of mods should i have done in order to get the full potential of squeezing nitrous? (So far just Basic Intake with AG piping, rebuilt head) Im planning to get a new exuast system 2.5 piping, and maybe an ignition upgrade.

3. What setup would your prefer for the 5mge.. I was thinking of doing a Dry shot set-up because i was interested in this air amplifier.
*It shoots directly through intake pipe, which forces more air into the manifold.
*this link will explain it a bit more. http://www.zex.com/information/products/nitrousairamplifier/

4. Will the AFM from the intake affect the Air Amplifier i was interested in. If so, is there a way to bypass the problem?

5. Any feedback, other comments on this set-up?!

*Please feel free to state your opinions, i wont be offended, i could give a shit... :twisted: Just as long as i get the honest truth.. LOL..

Thanx for the help.. 8)

Makes sense, but I know nothing about nitrous.
All I can say...

GOT NAAAAWWWWSSSS?????

j/k :silly:

Hey,
I got a 85 with 155k on the motor, i have a stock cut open air box and a 3in side pipe exhaust i made.
my supra went 15.6's on the motor all day long

I added zex 75 shot and i went first pass 14.50's and with some practice 14.30s

WARNING the dry kit work awesome as long as the vacum line stays on the fuel pressure regulator. mine is superglued and hose clamped
i wound not rec the air amplifier mine it tapped into the air pipe right above the exhaust cam housing

I think the Zex kit is a great idea for the dry shot (go wet with boost). Simple, and gets the job done. Their info leaves one feeling confident about the performance/install of the system. If you are going to end up drag racing, I suggest using a progressive nitrous controller. Jacobs makes a great unit for $330 or so, and works with our distributor type ignition. Cya!

My main intentions for the kit is for some drag use at SIR (seattle international raceway). But I've heard rumors that SIR wont allow cars to run with Zex nitrous kits.. Something about safety, not sure about it.. But i know they do allow NOS... But ohh well, if i cant run at the track i guess i'd be takin it on the street..

Judging from what I've read from the ad that you've provided the link for, one key item is missing. There's no mention of any need for a fuel enrichment system to go along with the "Enforcer" nitrous oxide gas injection. That is definitely not a good thing!! Someone could easily install one of these systems without realizing that they need a fuel enrichment system to go along with it. Very misleading and dangerous IMO. The tech inspection crews may frown on the ZEX system for this reason. Still, the system is an interesting concept from a technical point of view though.

There is a fuel "amp" kit that allows you to bolt it on..
*Here's the link.

Other than that, I dont see any other flaws about going nitrous..

allmotor85supra: How did you do your set up?! Did you do any fuel upgrades, get bigger injectors?!

I saw this on there web site.

Will your kit work on my car if it does not have a vacuum operated fuel pressure regulator?

No, our nitrous kit is not compatible in your application due to the absence of a vacuum ported fuel pressure regulator. The required fuel enrichment comes by way of this style of fuel pressure regulator.

Ok i can c u do not understand how the dry system works. The nitrous is pumped via a line and a nozzle into the intake pipe at anywhere from 900 to 1100 psi. The dry kit uses a bypass vavle in the fuel pressure regulator vacuum line wich allows the nitrous pressure to actually completely push close ur factory fuel pressure regulator. This cause your fuel pressure to jump for 36psi to high 80's. This extra fuel pressure cause all 6 injector to dump alot of fuel. That is were u get ur needed fuel for the nitrous.

The fuel amp booster is just a purple coated walbro 255L hint hint i use a mustang 255L all u gotta do is modify the pick up. I believe Rabid Chimp has the MK2 pump kit?

Well, color me blind, but increasing the fuel pressure from 30 to 80 PSI sounds quite dangerous to me!

HA HA how do u think 5mgte turbo setups get there fuel??? They use a rising rate fuel pressure regulator (RRFPR). As the motor creates boost it is routed to the (RRFPR) via a vacuum line connected to the intake manifold. As boost is applied to the (RRFPR) it raises fuel pressure in a set amount. IE a vortech FMU with 10 to 1 ratio is raising fuel pressure 10psi per every 1 psi of boosted pressure. So if a stock CT26 setup is running 8psi of boost it is the (RRFPR) is adding 80 psi of fuel pressure. In all honestly its like putting a set of vise grip on your fuel return line. Most (RRFPR) turbo vehicle at full throttle see anywhere from 80 to 100 plus. That is why a high performance fuel pump is recommended so it can handle the PSI needs and the volume needs. The dry kit works on the same principle. :idea:

Oh well! I tried! "Hats off to you". No pun intended. 8) Just be sure to keep a fire extinguisher handy!
