This kit only includes the fuel rail and the mounting hardware making it ideal for custom applications. This fuel rail is compatible with most Mazda 1.8L DOHC BP engines:
1994-1997 Mazda Miata
1999-2005 Mazda MX-5
1994-1996 Eunos Roadster The rail is CNC machined from extruded 6063 aluminum, black anodized, and laser etched for a high quality surface finish. All 3 ports are machined with 8AN ORB (3/4-16 female) threads. Like the OEM fuel rails, the injector bores are 11mm ID so factory injectors are permitted. This kit is compatible with all fuel types including popular alcohol mixtures such as E85. The OEM plastic spacers are reused and Phenolic washers are included to thermally insulate the fuel rail from the aluminum intake manifold.

Pros: Beautiful fuel rail, bolls on perfectly. Has holes for NA and NB heads, includes stainless steel hardware for installation but you will need the fuel kit or make your own.Cons: Uses -8 ORB fittings so you will need adapters since the Miata uses -6 hardware. You can find the kit for different years. I went with my own setup.

The idiot I am, I bought this for my 90’. It came perfect, well milled, no burs or anything. Even the threads were nice. Unfortunately the injector spacing is different on the older ones. No issue though, I’m keeping it and will be upgrading the intake instead.4 stars instead of 5 because I didn’t test it yet.
