Miata Engine Fuel System Package

This is the fuel system package I use on all of my engine builds, put together so you don't have to piece one together and hope it works. It uses Radium Engineering rail components with Fuel Injector Clinic injectors, and it can be set up for your engine, chassis year and power goal.

The package includes a Radium fuel rail for the 1.6 or 1.8, a Radium direct mount fuel pressure regulator, a Radium plumbing kit that connects to the OEM fuel hoses, a Radium fuel pressure gauge, and FIC injectors with plug and play adapter harnesses. For injectors, 365cc suits E85 and naturally aspirated builds, 775cc suits turbo builds up to 250 horsepower and supercharged builds, and 1000cc suits turbo builds up to 400 horsepower. If you need something bigger, email me about a custom package. You can also order it without injectors.

NB owners will need to convert to a true return style fuel system for this kit to work. That's worth doing anyway, because with the OEM setup the fuel gets hot in the rail, which makes tuning a nightmare. Here's a walkthrough: NB Return Style Conversion How To. I'm planning to offer an NB conversion package, but it isn't available yet.
