I have been planning on doing a cam and stall with a tune in a month or so, and Im thinking about going ahead and putting a ZEX 125shot kit on. Zex claims to have a safe product. I dont go to the track often so Id go once or twice just to get my times and the rest of the time I dont really see me spraying much on the street. Is there anything thats a must change out on a car thats not gonna spray more than a few times here and there or can I just install it tune and and run it.

 

Spark plugs, NGK TR6s are pretty popular.

So should the Stock fuel injectors and fuel pump be good enough and are NGK tr55s good enough spark to handle the 125 spray every once in a while?

 

If you do a cam I would suggest doing a fuel pump, like the racetronix kit. If you go with a dry kit you may need to do fuel injectors too. I would not suggest spraying on the TR55 plugs.

any kit is safe as long as its setup correctly and i wouldnt spray on tr55's your not losing anything going to tr6's

 

How are the tr6s when not spraying are they just as good as the tr55s.

 

Your idel will be a little more rough and you may have to change them out a little sooner then the TR55s.

I's be prepared to put a transmission in also.

 

If he is running an automatic just set the window switch to shut the nitrous off a few hundred rpm before the transmission shifts so you won't be shifting with the extra torque.
