Which brand of NOS?

[afastsbc]

I am going to purchase a wet kit for my G35 Sedan shortly. I own an american muscle car with NOS so I am familiar with its mechanics. My question is if anyone knows which kit is best for my import. I have found 2 brands, Zex and DynoTune. The Zex kit is about $200.00 more and both have what sounds like identical components. Also, regardless of which I choose, will my NGK Iridium plugs be ok? They will be installed at the same time. I plan on running a 50 shot on the street and a 75 or 100 at the track. Car is stock except for a cold air intake. Thanks for any advice...

Best for this in the FI sub-forum. But, since its here...

I know that most people run the ZEX, that has been they're favorite brand. I'm not too familiar with DynoTune.

A couple things to keep in mind....aftermarket intakes on the G have been known to run them lean without some exhaust work. Coupled with NOS It might be a good idea to get some exhaust up before you do use the nitrous. For the spark plugs, lots of people use the NGK iridium IX. The Laser Platinums are the stockers. If you're running pretty hardcore often, you might think about running 1 step colder plugs.

Hey...thanks for the help. Any ideas for a cat-back set up? I would prefer something on the quieter side but if the best is loud, then give it to me.
