Nitrous going on my 13sec 14b car.

[OneFastEclipse]

Ok, I am currently running low 13's on a ported 14b with a 190lph fp, 550cc injectors, and a SAFC II for tuning. I have a nitrous kit from my other car just sitting in the other room doing nothing. It is a wet kit and I am thinking about putting it on the GSX for a little more fun. My question is, how exactly should I tune for this? Should I tune the car perfect with the SAFC on just the turbo, then just use the fuel jets on the nitrous kit to tune the nitrous? I know how this works on a non turbo car but I am sure there are other factors when putting it on a turbo car. Do I need to re gap my plugs? I know they need to be about .30 on the stock turbo plugs, is this ok for nitrous use? I have a auto tranny, I thought about using the nitrous to get off the line alot faster. Good idea or bad idea? Lastly, how big of a shot is safe on a stock 4g63 bottom end? Thanks alot!

Most people just run it tuned about right on and then richen it up just a little since its a wet kit. I wouldn't go more than 20 lbs and a 75 shot, the nitrous will make you boost creep up about 2-4 psi from what you have it set at. I was running a 75 shot with 20 psi boost and it ran fine, upped it to a 100 shot and it was just too much power and the bottom end came apart, but it ran fine with a 75 shot.
