injectors

[1990e30coupe]

I know im posting a lot but the more info the better right? Anyways i was just wondering if anyone knows what i can rob injectors out of to run around 8-10psi? I was told a crown vic but not sure on what motor. Or if anyone can point me in the right direction where to look for some at a decent price that would be great, and if 30lbers would get the job done?

thanks!

A little out there but I know that rx7's use injectors out of a 2000 crown vic.......1600ccs

If you are going forced induction, the last thing you want is a dirty /bad injector causing you to lean out. You may as well buy injectors brand new. You can practically buy them in any flavor from these fuel injector places online. Thats just me though.

Ok sounds better to buy new which i wanna do deff... So will 30lbers do the job for 8- 10psi? Or should i do 34lbs and can they be tuned down enough for 8psi or will it be to much?

you want to be within about 80% duty cycle. Less is generally better, but unless you have a RRFPR you can sometimes run rich at idle.

What is the benefit of running an RRFPR vs. a regular FPR? (Noobie to the FI's, just started my build)

If your not running ms, vems, etc then 30lb units are your max and will easilymeet your goals. Flow matched refurbs can be found on ebay.

24lb injectors will just get the job done, 30lb injectors will handle as much as tuning will allow if you're planning on running stock motronic with piggyback, but 30lb won't start and idle like stock, 24lb will.

Fords are a good source of used injectors, primarily because there are a lot of performance enthusiasts circles in the ford category who have a tendency to be selling and swapping and upgrading tidbits constantly, I got my 30lb injectors free from a mustang guy who had bought them then decided to run 37lb injectors instead for whatever reason, and he literally gave them to me... all 8... even though I had offered to buy 6... however my experiences with most other mustang drivers have been drastically less douchey..
