I have a 2007 RX8 and I an thinking about hooking up a ZEX kit. I spoke to someone at ZEX and was told that to tap the fuel you have to cut the stock fuel line that there in no fuel pressure valve on my fuel lines to tap into. I dont like the idea of cutting into the fuel line is this the only way if I want to do NOS.

Hey Chrism I just ordered my Zex last week, I'll be heading over to see Ray before the end of the month!
Zoom f'n ZOOOOOOMMMMMMMMM!

 

QUICK! edit your post! change the "NOS" to "nitrous"

NOS is a brand just like Zex. You may get flamed greatly if you leave it especially since you were talking about using the Zex kit.

other than that, definately read the sticky, you will be well on your way.

 

you DO NOT cut the line... you replace it..... oh the nightmare i went through cutting and tapping it. first read stickies than if you dont understand after reading (like me) id be happy to help. just not a question the is very simple or else i would copy it and post it on a thread. =X

 

CRH is the man with nitrous and both the sticky regarding the subject, and his lengthy thread chronicling his experiences are good reads. He reccomends replacing the stock fuel line with flexible fuel line hose and adding a "T" to it. He details the hose specs in the sticky.

I've heard nothing but good things about zex in the 8s and in other cars in general. It seems that the wet system is the way to go dispite the slight increase in install complication.

I'm looking forward to doing this myself once the dampers, springs, wheels, tires, gauges, flywheel, AP pulley and Cobb AP are all purchased and installed. Can't wait, but I guess I'll have too!

 

who ever is local to me is always welcome to see CRH's work in my car.....it truly is an artform!

 

When you add together the installation of a dry system to a management system that will know when the nitrous is open and adjust the fuel delivery, the wet system could be argued to be the easier.
