The 803 that I think is used is 0-280-150-803, which is std fit PORSCHE 944 TURBO, 2.5l 4 pot.
Most injectors are 2.5 or 3 bar, but some are 3.7 bar notably PORSCHE and CHRYSLER, but this porsche is 2.7 bar, does not matter that they are getting less bar on a cossie, it's all calculated when chip is written.
All I am saying is be careful as there are many exact looking injectors but wholly different flow rates.
