The DeatschWerks P1-P2 adapter kit is an easy way to run the newer and more reliable phase 2 injectors in an older phase1 fuel rail. No longer do you have to source a new fuel rail, and machine your intake manifold. This adapter kit is commonly used for Nissan Z32 300zx (6-cyl), Infiniti Q45 (8-cyl), and some early model Subaru’s (4-cyl).
