ZEX kit question. Hi, I have the dry kit #82011 (which was origionally meant for 4&6 cyl) and I was wondering, is it possible to install larger jets to use on a '02 Z28? And where will the fuel vac line go? I didn't see a vac connection on the FPR. Anything I should know before attempting this?
you should be able to up the jet size, don't see why not. i have the zex dry kit on my car and i just got some rubber emissions caps and capped off the fittings labeled "intake" and "regulator" on the box because our cars don't have a vacuum controlled fuel pressure regulator. make sure you put those caps on and zip tie them on tight because i blew one off at the track the other day and it didn't spray for crap with it just sitting open.
Hallass is correct, I sold him that kit, and if those caps blow off, the kit will not work, I do not recommend anything above a 100 shot on a stock LS1 fuel pump, upgrade to a Walbro and do not go above 125, and get it tuned. Never cut corners when it comes to the juice, or you will pay with a engine replacement.
actually i need to correct the info on this. i could not keep the caps on the fitting and they keep blowing off, keeping the kit from spraying properly. i called zex just a few minutes ago and they said to loop them with a small hose, and clamp it on so that the kit reads that it is getting fuel pressure, and doesn't blast all that pressure trying to raise your fuel pressure, popping the caps off.
