nitrous
oh look on ebay at blue oval preformance i found an NX kit for 580 and it has free shipping and they knock 35 off the price for a fill. http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEWA%3AIT
I'd say go with the Zex wet kit... it will run 75, 100 or 125 shot and is simple enough to set up... they say 0 timing retard for a 75 shot, 2 degrees for 100 shot, 4 degrees for a 125 shot. There's a rule of thumb around somewhere for shot size to timing retard... better to get a chip that will store two tunes if you end up running over a 125 shot... one tune for street driving, and a second for when you use nitrous.
Cobra motors will be able to take a little more of a shot than a GT... not much though. Like it's been said, 75 is perfectly safe, 100 is pushing it, and 125 will be ok with little use and a good tune.
