So a wet 50-75 shot (any company), a walbro fuel pump, AEM FPR, wideband, colder plugs, and retard the timing and its good??

My friend is planning on getting an EX and then putting a NX wet system on it. Along with intake/header/exhaust.

 

i highly recommend zex for the begginer n2o tuner. its almost a plug and play affair. i cant say much on the wideband as i tune by plugs alone while using n2o. i have used the nx direct port kit and loved it......but the nx direct port kit doesnt come with jetting for less than a 100 shot, dont beleive what the websites say, when i got both my kits in they both did not come with 75hp jets. the nx single fogger wet kit though is a nice choice also. i do like dry kits also when running less than a 100 shot. they kick harder and faster imo, and when bottle pressure is low you can still use the nitrous as fuel gets compensated per bottle pressure. with a wet kit and low bottle pressure you end up running extremly rich. also with a dry kit you can empty the entire bottle and actually be able to use it.
