-LS Block
-LS Rods
-CTR Pistons
-B16 head
-Crower Valvetrain
-ITR Cams
-NGK Plug Wires
-Skunk2 Intake Manifold
-AEM Fuel Rail
-Adjustable FPR
-Walbro 255lph Fuel Pump
-stock gsr injectors

 

come on nitrous gurus!!

 

Are you wanting to run dry or wet kit??

 

I wouldnt spray **** on it untill its tuned for the nitrous....thats pretty high compression. I would stay on the safe side.

 

i have a dry kit, thinking about running a 50 or 75 shot

I definately would not run a dry kit on a high compression motor...from what I've read you wanna stick with a wet kit on that kind of setup. But I am not a expert on this.

 

whos the nitrous experts around here ill pm them...

 

i dont think youre over 11:1 with that setup, but yeah, get it tuned.

spray is wack, incase you didnt know.

 

bump again for a Nitrous GURU

 

with that kind of compression I wouldnt run over a 50 shot plus your still running oem pistons. Either way your going to have to have some way to retard ignition and add fuel.
You could increase fuel pressure and retard at the disturbertor but then ur asking for it. You also need some colder plugs to spray. Yeah nitrous is pretty wack, I just went from a turbo to a 50 shot and hate it. I like spraying but that stuff cost 40 bucks to fill up a 10lb tank and you have a 1200 psi bottle sitting in your car, proabably not the safest thing especially if your not running your safety valve out of the car.

 

I had a built gsr motor with ctr pistons and a 55 dry shot. I had my engine tuned on motor. I never had any problems at all but, you will need to retard timing. Also don't use platinum spark plugs with nitrous. Put some Ngk BKR7E spark plugs in your engine. Those plugs are colder stage than stock and can take the heat better than factory. Definetely get your engine tuned before using nitrous cause you sure don't want to be running lean. If you're running lean on motor and then try to use nitrous your probably not going to have a happy ending.

 

I have sprayed on 12:5 compression before a 100-shot but I had a separate fuel system for it and it was on 112 race gas and tuned for the shot. I had digital 6 msd box for on the shot it would retard the timing and off the shot the timing would be different. It was activated by a toogle switch you hook up to the msd box. Remember tunning is key and I had a direct port shot and I would spray on a wet shot instead of dry. Be careful this is not a shot you want to play with especially with compression that high. You must have a good turner who knows what he is doing.
