need help install zex on gsr
 

hey guy,where do you recommend install the zex amp. and what other mods. do i need to get before spraying it...thanks:thumbup:

Get one heat range colder NGK Copper plugs...BKR7E...gap them around .035".
Make sure your timing is at the stock mark of 16° for the 55 shot.
I mounted my box on the firewall, but you can mount it wherever you want, provided that the nitrous hose will reach the intake, and the vacuum hoses will reach the FPR and intake manifold.

i 've order zex plugs is that any good..and what if i go 65 or 75...i have i/h/e stock timing...:thumbup:

you can run a 55 shot bone stock with the exception of the colder plugs.

if you bump up to a 65/75 shot, you need to retard the timing and seriously consider an aftermarket fuel pump to safeguard against running lean. i've heard of people running up to a 75 shot on a stock fuel pump, but i personally wouldn't want to risk it.

another option on mounting the zex CPU is on the plastic battery cover. drill some holes in the side of the battery cover to match up to the mounting holes on the CPU box and then secure the box with a couple of zip ties and you're good to go. this setup is going on two years in my car without a problem.

let me know if you have any other questions.

You don't need a fuel pump going up to a 75 shot, but you will need to retard your timing. The stock fuel pump can handle the 75 no problem. As for the zex plugs, speaking from personal experience they are crap. I owned them, and switched back to my NGK's.

i'm running a 55 shot. I didnt retard my timing or get colder spark plugs, and so far so good. But I am going to retard my timing 2 degrees and get 2 step colder plugs since i wanna be on the safe side

but on the idea of mounting ur zex box, i'd say try to hide it as much as possible. I was pulled over and the cop was staring at it for a while. Although he didnt ask me what it was, i painted my box black so it would blend.

If i could put it anywhere, it would probably be under my intake manifold for the sleeper look, plus no cop hassle

thank 4 the help fellow..what gears does you guy hit it in, i was told never in 1st but in 2nd in on..and how much power &felt can you can feel when it kick in....can wait to install mine:thumbup:
