Only thing I can contribute is that maybe the Zex isint using quality components. One thing I read is that some low buck N2O systems use valves from soda machines (Co2) to make them cheaper and they dont hold up as well. Try asking about this in one of the tech sections. Theres more guys with experience with it there.

 

Where's Revhead??

I think he has a reply for you..

 

Whoa, whoa, whoa!! I installed a ZEX system on an Integra and it was extreme quality stuff. His problem lies in the concept behind the ZEX. Up until the middle of this year (2003), ZEX only made dry systems. They were designed for EFI cars exclusively. The system tricks the car's box into ramping up the duty cycles of the fuel injectors to get the fuel necessary for a safe burn of the nitrous being injected by the ZEX. That was why you never saw 400HP ZEX systems. No factory EFI car with its factory fuel injectors could hope to inject enough fuel to safely use the amount of nitrous for those kinds of big hits. You need a wet nitrous system where fuel is added by a separate solenoid along with the nitrous solenoid. I believe ZEX has just entered this market with all the solenoids still contained in one box. I don't know that for sure, however, I just know someone has attempted that approach.

It's still possible to run a ZEX old school system, but you'd have to run your Webber's fuel jets constantly on the rich side for the 50 hit. It's the same idea as the tophat ring used by NOS for the Holley carbs. Nitrous only, but small hits only, as well.

 

mar3, I said MAYBE dude, as in speculating. Glad you have some solid info. Thanks

 

watch for flying apex seals, lol

 

I'll keep that in mind when I use the 100 HP jets on the '83's stock 154,000 mile engine next Spring at Kennedale...

 

wouldnt it be eazer to just get a webber with no2 ports?

 

no2 ports?

where can i get that?


and do they make it for the 48IDA?

 

ZEX won't work due to the computer not adding additional fuel to the mixture. Second gen computers make air/fuel adjustments, FB computers are closed loop meaning the factory set the spec's and the computer just follows the program given.

 

Don't tempt me.

 

go on.. say it..

u think yur so good..

jk

lol

 

N2O, pet peeve of mine when people say it "no2".
