Ok, I have a ZC motor in my 89 CRX and a 15.4 with a 2.4 60ft just sucks. So... I'm ordering slicks and a N2O kit. Just wanting to make sure I know everything I need to do. I will be starting out with 50 and moving to 75 shot.

Colder spark plugs. KGK # 3330
Retard timing 3-4deg
Increase fuel pressure.

I also have some Prelude 325 or 345cc injectors I may run to make sure there is enough fuel.

Also what size slicks should I run? I can get 20, 22, or 24.5".

 

wet or dry? i dont think your car will even idle with those injectors in it. way to much fuel.

 

Wet. Ok then, just thinking it would be a safeguard against running lean on nitrous.

 

lean is rarely the prob, timing is everything. to much retard can be bad just as not enough.

So do you think 4deg is too much for a 75 wet shot?

Also are the NGK 3330 plugs good ones to run?

 

I would read enerything that comes with the kit and do what it tells you.

 

Use a wet kit so no additional fuel is necessary at the injectors. I would run 16 degrees base timing w/ a 50 shot, and would not retard timing more than 2 degrees w/ a 75 shot. Run NGK 7's gapped around 30, and make sure everything else on your motor is up to snuff. A high flow fuel pump is a very good idea if you don't have one already.
