Anybody use one of these kits? What would the best shot to use on a totally stock (and brand new) 5.3

 

wet or dry?

I have a zex Wet kit and a MSD cut off on mine? i am spraying a 200 shot with no problems on a stock bottom end and i have the timing retarded 4*. Msd cut off at 5900 for shifting makes it a nice way to spray out of the hole and not **** my tranny up to bad.

 

i am really wanting to spray my truck also. i need to get a kit soon

 

I've heard good things about the Zex kit - easy to install for a n2o first-timer as well

If it were me I wouldn't spray over a 125 shot on a stock motor, but just me

 

I would definatley recomend the zex kit !!!

I have a bottle heater and purge on mine you won't want to go back once u put it on!!!

I have been running a 100-200 shot for over 20+ bottles and no problems but that is mostly b/c it is a wet kit and the MSD shut off !!

 

Yeah most people have told me that i also upgraded the fule system and plugs.

 

how are you guys spraying 200 HP on a zex kit? I though the limit was 125??

i am running a nx wet kit. i am spraying a 150 shot on the stock bottom end. i do have a cam and springs. i think if it is run properly with the correct fuel and the kr is watched you will be ok. i think a zex kit can be rejetted to run a higher shot. i think the tranny will be the weakest point.

 

02's exactly right... your tranny could get messed up pretty easily. Mine original 4L60E kicked the bucket after about 5,000 miles of moderately hard driving post blower install. You could do the responsible thing and beef it up before you spray, or be like me and beat it to failure first. I would be a little wary of spraying above 125 with a stock drivetrain and internals.

What is the biggest Dry shot you could run on one of these stock engines.
