i want to shoot a 50 shot to my car, i was at the drag strip last night with the car and had that itch to get my times down..so heres what i want to do..i want to shoot a 50-75 shot reliably..what can i buy to make everything alot more safe? should i get bigger injectors fuel pump? adjust timing? thanks for the input by the way i ran 4 times and the best run was 15.5 jdm d15b spare tire and jack in the back with all my gf's crap

 

umm, I'm no nitrous pro, not even an amateur, but I've read that alot of the guys here will run colder spark plugs. Might want to read into that.

 

yeah i knew that im looking for answers on like fuel control tuning stuff like that i just want to do everything right

 

i had a DOHC ZC in my old rex and i ran spray (70 shot) every weekend until i sold my car with only colder plugs lots of octain booster and retarded timing. i never had any problems

 

anybody have a suggestion on what plugs to get, i have a jdm d15b do i just go to the auto parts store and say i want 1 or 2 step colder plugs? thanks for the help

 

The most important aspect is not to overindulge. Choosing the correct kit for any given application is essential; a good rule of thumb to follow is never exceed 50% power increase to your current engine output....

so what are you plan on running a wet or dry kit. I recomend a wet kit. I ran a 200shot NX wet kit w/ shark nozzle on my 04 GTO and i ran a cold plug..

Conversely, a "Cold" spark plug has a shorter insulator nose and absorbs more combustion chamber heat. This heat travels a shorter distance, and allows the plug to operate at a lower internal temperature. A colder heat range can be necessary when an engine is modified for performance, subjected to heavy loads, or it is run at high RPMs for significant periods of time. The higher cylinder pressures developed by high compression, large camshafts, blowers and nitrous oxide, not to mention the RPM ranges we run our engines at while racing, make colder plugs mandatory to eliminate plug overheating and engine damage. The colder type plug removes heat more quickly, and will reduce the chance of pre-ignition/detonation and burn-out of the firing end. (Engine temperatures can affect the spark plug's operating temperature, but not the spark plug's heat range). Hope that helps. Good Luck

 

i want to run a wet kit, i have also seen direct port kits has anyone have had expirience with these?. anyone have any kit suggestions? i will be getting something within the next couple days so i can get to the track next week or the week after that

 

direct port is a waste of time for your application, seeing how i doubt your motor is built. Nitrous can be the enemy when u get to big of a ego. I would run a fogger sys. or a shark nozzle wet kit. Its easy to install. And if you want to be sneaky there is someplaces you could hide the bottle. I had a hidden system on the gto. i had the bottle tucked under the car in the rear fender... so sneaky ...

I woudl get this kit if i was you

i would use spark plugs 1 or 2 from stock...if ur going 70+shot...i would retard timing 2 degrees especially if ur running chiped ecu.the chips automatically advance ur timing by a few degrees.injectors is good but not a must....fuel press regulator would be nice.hope i helped a little

A quick question for you man? How fast was the gto. thats close to 600 ponies.
