INTAKE MANIFOLD COMPATIBILITY
This fuel rail kit is designed for the Nissan S13 SR20DET (RWD configuration) intake manifold. Radium Engineering has NOT tested on any FWD SR20 intake manifolds.

NJECTOR COMPATIBILITY
The Radium fuel rail converts from side feed fuel injectors to top feed, allowing the use of high flow aftermarket fuel injectors. Fuel injectors are not included and not sold by Radium Engineering. Reference the diagram below to ensure compatible fuel injectors are obtained. For this fuel rail, a 34mm tall universal injector with 14mm upper and lower O-rings must be used. Most popular injector suppliers offer a fuel injector in this configuration. Refer the injector supplier to this page if needed.
NOTE: Short 34mm injectors are used in this kit because hood clearance may become an issue if taller injectors are used.
