Hey im new at this site but it seemed pretty cool so i wana see if u guys can help me out...

i have a 2005 chevy silverado stepside 2 wheel drive
mods: flowmaster 40 series, k&n drop in, 4.11`s, posi locker and well now its time for a zex nitrous kit....

just wondering if there was anyone that has installed it that could help me with pictures, wish color the WOT wire is, where get the fuel rail etc...

thanx

 

I have a zex kit in my truck..... There is a fuel check valve that is under the cover on top of your motor on the fuel rail the valve has to be removed from the line with a tool and then that is were you will connect the fuel line. Look at the top of the picture on the fuel rail see the black cap nut that is where the fuel line goes. The green wire on your throttlebody is the tps wire that you will hook the wot wire too. How big of a shot do you plan on doing? Might want to beef up the tranny.....

 

wow! perfect thanx a lot man! and im planning on using 125 shot wish is 98hp rwhp right?

sorry i forgot to mention that my tranny has a little bit work done too, it has a cooler, a temp gauge, they changed a valve in the pump, corvette servo and i bought the 4L60E - HD2 TRANSGO High Performance Shift Kit wish i will install b4 the nitrous kit.....

i have a stall converter at 2500 rpm

ok and i bought the zex plugs, are they good? do u use em?

thanx a lot!

 

I use ngk tr6 gapped to .035..... Do you plan on pulling some timming from the computer with that nitrous shot? 125hp shot should be close to 125rwhp it all depends on the application.

 

u think the zex plugs will still do the job? cuz thats what they told me when i called them....

and about timing im not sure, u think i should? or am i safe not doing it? i usually will use 75 shot but i wana make it ready so i can use 125 shot safe

 

I pretty sure you will need a tune for anything over 100hp shot on the stock tune. Just make sure the zex plugs are gapped to .035.

 

ok i will make that sure... and about the tune, the reason i was gona wait is because i have the cam already but not installed i wanted to wait till i had the money to install it and take it to a dyno but then maybe i`ll change that... what kinda tune would u recommend me, the cheapest just for the timing cuz at the end of this year i wana go to a dyno anyways so i dont want to spend to much...

what are u using?

thanx

 

Mine is custom dyno tuned.... The paperwork that comes with the zex kit tell you how much timing is needed to be removed per shot size.

 

oh ok... well ive heard good stuff of the diablo sport, that u can program it urself, are they easy to use, u know anything about them?

 

anyone else that could help me here out???? any cheap tune or do i have to order something like nelson tunning??

thanx
