I ordered these Denso 520cc injectors for my rb20. They are used but have been cleaned and tested. Stefan from Performance Injection stated they would fit a rb20det. There is no way they will fit into the fuel rail. Stock size that fits into rail is 9.80mm and the Densos are 10.45mm. Would someone indentify what car the Densos fit. The Denso is the one on the left.
