i have a 12a with a nikki carb and i put a turbo 2 turbo on it now im trying to find out what jet to put in it if i run 6-7 pounds of boost.

 

First off, is your carb boost prepped? You can't just slap a turbo onto a Nikki and call it a day. Second your going to have to go through alot of testing before you get the right jet size. Your area's climate and elevation have alot to do with how the carb will run. Buy a bunch of different size jets and start from mildly rich and go progressively leaner until your happy with it. Also, use the search function. Turboing a 12A has been covered a few times, so you may just find the info you need to get you going.
