I'm getting a new engine but in the mean time...best NITRIOUS system?

I have been reviewing NOS and ZEX what's the best Nitrous kit to get and which is going to love my engine more.... which spells no excessive wear.

Thanks

Twisted!

Nice...

Any of these systems have compartment arming devices? Or do they all?

how much did the "shark toothed" nozel set you back? Or did you get the F&F logo one...

I'm thinking about getting a second bottle and keep her on garage. Zex bottles are like $210 a piece. ouch!

NX does not list prices....

Edelbrock states no prices either....and mention uping fuel pump and ignition systems on high HP installs. I'm looking at 75hp to 125hp.

Thanks
