These injectors were in my Twin Turbo EG33 for about 6 months, less than 5000 miles. I was able to run E85 and 10psi of boost without issue. Flow test data included, both from factory and a second test I paid for. Megasquirt Tune available if desired. Requires pigtails ($17) for installation on EG33. These are normally sold for the 300zx or R32 skyline but work very well in the EG33. Pigtails Characterization Data $350
