1ZZ Injectors on NA Setup
I'm kicking around the idea of upgrading to 1ZZ injectors, but I'm wondering if the hassle of disassembling the top of the engine to do to the swap outweighs any potential benefits I might see.
I have a basic NA setup, with a few bolt-ons: AFE intake, NST pulleys, 1ZZ TB with spacer, Megan header & axle-back with custom mid-pipe. I have no plans to do a turbo, s/c, or nitrous, so I'm looking for input as to whether I should bother with larger injectors at all. If I do decide to do the swap, do I need new coils and rail? Or just the injectors? Is there any way to do the swap without removing the valve cover and exposing the cams, etc? It just seems like I'm opening a door to potential problems by digging that far into the block. Any advice would be appreciated. |
