Okay before everyone comes in and flames me please read and try and understand what I am asking. I have an S14 SR20DET that a friend of mine got me from japan. The motor is from a shop and not a wrecking yard. It was pulled from a car and I was told in perfect running order( I pulled the valve cover off and valvetrain looks brand new). I was also told it had a HKS head gasket and HKS Rocker arm stoppers. They said it had an aftermarket turbo and manifold but that was not sold with the motor. I am not sure what size turbo was on it but there is a stainless steel oil line still on the motor. Okay so my question is what pink side feed injectors would be on my motor? I have searched everywhere but I can't find what size injectors they are. They are on a stock fuel rail with a nismo fuel pressure regulator. Any help would be awesome thanks.

Are you sure they aren't top feed? Yeah it has one rivet sticking out. But I have an APEX'I HG and Mazworx custom head studs going in it. I also have HKS cams and all kinds of goodies waiting for it. But if I don't have to buy new injectors because these flow well enough then it will save me money $$$. It didn't come with any wiring or computer but I sourced those elsewhere. I plan on using the stock ecu with an enthalpy tune if I can figure out what injectors I have.

go ahead and get an safc.. just version 1.. NOT TO TUNE WITH, but as a monitor.. you really want to monitor your duty cycle...


get a stock ecu and hook up the safc... trim the fuel 50% (thats as much as it will trim). see how the car idles/runs... if its decent, then the injectors are 555 >
