So I increased my X1/9's potential output with increased compression and more camshaft. And the fuel has gotten alcoholic since I ran it last 7(!) years ago. Now the injectors are seeing full duty cycle by about 5500 rpm at WOT, and I am still lean. Megasquirt 1.2 that I installed and tuned to old compression and cam 13 years ago. Looking at the Bosch style used, it appears the same seals and hoses as 280Z Datsun. Datsun 460 cc per cylinder. Fiat 375 cc per cylinder. Does anyone on the board have 4 injectors from a Zcar they would part with? racerwag@gmail.com.
Similar style to those used on many Bosch EFI equipped cars of the eighties and nineties.
For example, here are some Injector ratings for Chrysler 2.2L Turbo engines:

Your 460cc injectors work out to about 43lbs/hr (depending of the base fuel pressure, Chrysler uses 55psi on their cars, yours might be different).
So this might help in your search to convert your cc/min number to lb/hr and adjust the base fuel pressure as well.
Good luck on the search
In reply to Stefan :
Indeed they are similar to many. I have 2 sets from Volvo 240s, which won't work because the Volvo uses a metal "rail" with the injectors clipped in. The Fiat and Datsun have separate hoses from the rail to the injectors, and the same pump & filter.
I have a couple of sets from Datsun 280zx's. But, there's no way they're 460cc injectors. Let me know if you want them anyway and I'll email you.

280Z stock injectors are 188cc units
280ZX Turbo stock injectors are 265cc units
Are ZX injectors the same as early 280Z? I stopped working on daily driver cars when they were still newish, and I do not remember. The 460cc number is the cylinder displacement, not the injector size. I have no idea of the actual specification for my Fiat injector, but the 375cc is my per cylinder displacement. Early normally aspirated 280Z injector is physically identical to my car, and I am now going lean about 5500RPM at WOT. I would like to get to 6500 without lean damage. Looking at the specs you posted, I think the Turbo injector will be too large, making my low speed hard to tune. It idles at 800 and works super now from 1500 rpm and this is my DD car, so low speed matters!
Somewhere I have a spreadsheet that would tell you what you want. I think you may be looking for brown tops from a Ford super coup. Those I think are 42lb ones.
In reply to dean1484 :
They might also work, I have never seen a Ford Super Coupe close enough to know if they have the hose top.
In reply to TurnerX19 :
Local pick and pull. There are 4 of them here in Sacramento
In reply to TurnerX19 :
They're not, they're standard Bosch EV1 style with a 14mm o-ring at each end.
Also if I remember you can look at the ones from a GTV3000. Turbo.
In reply to Matthew Kennedy :
Thanks Matthew, I have a 2 sets of that type from Volvos.
Thanks to forum member mikeatrpi I now have one and a half sets of larger injectors for my X1/9. Stoicheometric 6500 here we come!
What your is your x? Looks to be 80-82?
In reply to dansxr2 :
June of 1980 with an 81 title. Very early injected car. Strada final drive, tri-y header, serious weight loss program, mega squirt 1.2, MBW cam, 9.2/1 compression. Weighed 1982 with 1/2 tank of gas when scaled 8 years ago. Daily driver!
I loved mine. I had an 81, 79, and 2 '87's all at seperate times. I loved it! I would love another someday!
Also, if needed I have a set of 460cc RX-7 Redtop injectors with plugs. They worked great in my F2T powered MX-3, only reason i removed them. I only tookthem out to go with 630's and more boost. If interested, PM me.

Far up on this post you will see that mikeatrpi got me covered.
