Default 2005 Mazdaspeed Miata Injectors for sale.

Just got these in today from a fellow Miata Turbo user, decided to go a different route, so 60 dollars shipped... There is so much confusion regarding the flow rate of these injectors, but from what I most gather these are somewhat different from stock 2001-2005 injectors and they should flow around 315cc... But in other words they flow better than maroon top injectors and they atomize better than 1994-1997 injectors and flow a little more fuel as well. (The in-line fuel pressure is greater on the 99-05 returnless setup than the 1990-1997 return system.)

They have around 22,000 miles on them.

Yes, but they really do like higher fuel pressure.

These are indeed 265cc and are plug and play for any 90-05 Miata. He bought these from myself and the person I bought them from said they had 22k miles on them when pulled. The spray pattern is better than other stock Miata injectors, so if nothing else buy them for this reason.

Hahaha, I love the fuel injector confusion! But finally I have researched this and from what I have come up with is that the tan top injectors on a 90-97 Miata will flow around 265cc at the standard fuel pressure of 48.5 psi. Maroon top injectors on a 99-2000 flow the equivalent, however the returnless fuel pressure is more like 58-60 psi. So if they are installed on a 90-97, then they will flow more like 240cc. 2001-2005 Purple top injectors on a 90-97 will flow 265, yet on a 99-2005 with the higher fuel pressure they will flow closer to 300cc...

there so much arguing back and forth on flow rates its not even funny. I have even heard that msm injectors, though phsyically identical in color to the 2001-2005 injectors, actually do flow more according to BEGI. I would like some fuel injector god out there to prove us once and for all the true flow rates of blue top, tan top, maroon top, purple top, and msm injectors (if they are different from purple top)

Now its totally understandable I will be called an idiot and somebody will flame me, i'm ready for the horde

btw, no longer for sale, these bitches are going in my car...
