Hells yes. Im going with some ID725s when I get the dollars.

To get a newer injector? Yes. But for a rebuild? I meant RC for rebuild, I've heard better things about them than DW. That's a $80 vs. $100 debate, you're describing a $200 vs. $??? debate.

got the rc 270's out and packaged, droped the oem injectors back in and found out one is dead. oh well no miata for a couple days.

so i have been running around on around 4-5psi depending on ambient air temp, and of course i want more so ive been looking at mbc's yay or nah on this one

Link broken.

Just stay away from the in-cockpit ones, they don't work. Like this:

You're safe with pretty much anything else.

its this one https://www.miataforumz.com/attachme...ine=1331508577

That's the $5 one that everyone builds at Home Depot, I chose one that looked like it had an easier body to zip tie, and had a nice little knurled knob for slightly more precise changes. Can't find it currently, they're constantly changing I'm sure.

And I'm not saying you should just build it yourself, for $15 shipped it's worth the savings in hassle and time, at least for me. If it's over $15 shipped, make it yourself or look elsewhere.

its 20, and uses a allen wrench to adjust. says lifetime warranty to, so thats a plus
my personal opinion is if it cost 15 to make it yourself, and 20 for someone else to and then back it with a warranty its worth the extra 5 so i dont have to source parts and mess with it.

I prefer this mbc:

this is what FM used to sell for $40. you can make it for around $15. This is what I use(d).

where do you source the ball and spring from?
