Set of 6 80lb injectors (Siemens). These may look skinny but they fit perfectly in the Turbo Buicks. Good for cars looking to go 9.80's to 11.0's in the 1/4 on race gas, or down to around 10.70's on E85 (maybe faster depending on combo). Requires no ECM hardware modifications (will require matching chip or programming). Not for 84/85 Buicks without an 86/87 ECM. Typically flow within +/-2% of each other. Very good street manners for an injector this big, almost as good as the 60's. Be aware that a 255LPH single intank fuel pump can only supply enough fuel for 60lb/hr injectors. To use the full flow of these, you would need around 340LPH or a double pumper setup.
