90 NA 2+2
Wondering what brand and size of injectors I should buy as a replacement for the stock ones?
Can I go to 500+cc without drive-ability issues? What size are the stock injectors?
Thanks Mark

You need OEM injectors (270cc), there is no point in upsizing on a NA unless you plan on adding boost and tuning. Many recommend getting the retrofit kit and phase 2 (new style, 93+) injectors since they are pintleless and more reliable. Beyond that getting anything but the OEM injectors will be useless. Also changing injector size requires a tune, you can't just pop them in and go.
