i have a stock set up in my 84 gn right now and was wondering what size injectors i could go to with out to much trouble. I have a new stock turbo that i got from jay frick and kenne belle headers but thats about it on the car. I have a chip but dont want to put it in the car till i get the fuel right. I was also thinking about the walboro 340 kit. any input would help thanks in advance harry
