which injectors to get???

[89accordlxi]

I looking to order some injectors from nopi but am unsure which ones to get. what does "exc. Cal." mean? If I live in the mid west, do I get the ones with or without "exc. Cal."????
Thanks for any help.
Peace...

Get RC injectors.
I don't know how many CC's you have but an upgrade can do some good in the long run after all your I/H/E are installed.

where can you get them

ok, here is the formula to calculate what kind injectors you will need to get (i borrowed from JCwhitney webpage).

To choose correct flow rate, multiply car's maximum horsepower (be realistic) by 0.45 (nonturbo engine) or 0.55 (turbo), then divide by number of injectors. If the number you get after computing falls between the flow rates listed, always select the injector with next higher rate. Example: If you own a Honda 1.6L 225 hp 4-cylinder, multiply 225 by 0.45 and divide by 4. The result is 25.31, indicating you should order injector with 30-lb./hour flow rate. Note: The brake-specific fuel consumption figures of 0.45 and 0.55 are approximate; dyno testing will give you the exact figure along with your exact maximum horsepower.

exc. Cal means excluding California models. Those are the ones you want.

thats not entirely accurate, but it will work well enough i suppose.

if our A20 made 200 hp at 6000k, but a build VTEC makes it at 9000, you can be sure the 9k is gonna need bigger injectors.
also especially to keep from maxing the duty rate.
then there is displacement... :p
