you can't use a zex kit due to our old *** closed loop ecu. you'll have to run the NOS brand or an equivenlant.
However a "complete" nos kit will end up costing almost as much a blow-thru turbo system. When you add up all the extras you have to buy, plus the bottle refills are expensive.
I considered all this and just figured to go cosmo in 2 years. My bro is already finishing up his t2 project. and he'll still have more power then a sprayed first gen.
Just some things to concider...

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.

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.

Thanks

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.
