I would like to put nitrous on my car. I am looking at a 45 dry shot and i have a b18b. I was wondering what should i have done to the car before i install it and how hard is it to install? thx

 

45 dry truthfulyl isnt worth the time , by the time it gets to the wheels, it wil be noticeable, but fuggit dude go with 70-80 shot, get Zex they work great with dry kits.
basic rule of thumb is get colder plugs, some say 2 steps, but i have ran 1 step with no probs. , timing retard like 1 degree per 50 hp , but i have squeezed 80 wet on stock timing many times.
other than that , i mena you can run it on a stock car, i ve sen it done many times.
theres just other little things to get if you want to run bigger shots and be safe.
biggest thing to watch for is detonation and leaness probs.

 

I've installed a dry kit in 6 hours with a buddy. Keep in mind that this was in a show car and everything had to look pretty. It's a really easy install.
