Well, when are you putting them on? If you plan on buying them and bolting them on now, you'll need stock since your ECU isn't programmed for anything bigger. If you just plan on buying them and have 'em sitting there until you go turbo, it really depends on what kind of boost you want to run. Low boost: (<10 lbs) 370cc. High boost: (>10 lbs) MSD 50# injectors. You can get both of these and the fuel rail required (if you run MSD stuff) through Terry Vincent of FTF Motorsports. He's a good guy; he'll hook you up.
