Call nitrous express 1-888-463-2781 and buy the jet assortment and jet card. Its cheap, buy Relay NX part# 15515 its a 40 amp relay with wiring harness. 30 psi FPSS will be fine. If you dont have a 255 in tank pump I would get one before you go over a 100 shot and get a set of plugs one range cooler than stock. You need a bottle heater and Nitrous pressure guage. Part number 15939 for bottle heater and guage. Pull 2 degrees of timing for every 50 shot to be safe. 1st 100 dont have to pull timing but for a 125 pull 2 and for a 150 pull 2 but some pull 4 at a 150! Ask your tuner on your set up/ compression etc.

my sheet says a .030 fuel jet and a .046 nitrous jet should equal a 100 shot.
BUT, that is ZEX though but it should get you close. to be absolutely sure, call NX tho. they will be able to help

as for a nitrous pressure gauge, i got a gel filled one from NX and it is right on the bottle nut fitting where the feed line threads on to the bottle. as for a fuel pressure gauge, i think somebody makes a fuel rail block that has 2 places for fittings, 1 allows you to feed you N2o kit and the other is for a fuel pressure gauge. i know ZEX has that block but im sure others have one too.

a relay is a relay, not going to matter as for brand as long as you get one that is able to handle the ampres. jetting is just a reference chart, but you should be able to find it on nx's website. as for fpss, its the same way as relay. get one that is made for fuel injected cars and use it. the gauges are up to you on brand and placement.
