I found a good deal on SARD 800cc (63565) top feed/high impedence injectors. I want to use them on a future top-rail SR20 project, but the only info I can find says they fit RB20DET. ECU will be re-programmed. This is the same ones: [http://optionimports.com/sa80topfehii.html](http://optionimports.com/sa80topfehii.html) Will these fit an SR20 intake? Like is the injector base diameter the same? Thanks ---

well stock Rb20 injectors are the same as KAE 270cc injectors, so if you can get your hands on one of those to measure it with a micrometer or vernier, then measure your intake you’d know. sorry, i dont have access to my garage or i would measure them for you. ---
