I have searched all over this board and have read that ford injectors are supposed to be good. However, I don't want to get 24# injectors because all I have on my 91 TPI 350 are headers, exhaust, AFPR, gutted air box and TPIS air filters. I would like to get 22# injectors, because some of mine are starting to go, but there doesn't seem to be many choices. I found these two types which are reasonably priced and was wondering which would be the better choice.

TPI Bosch/Ford - 22lb
New-motor Take-outs

Bosch 0280150561 D9B-22lb

 

This is the other type

TPI Design III - 22lb
NEW - Upgrade
Bosch Design III - 22lb

0280155890, GM 12555894

 

unless you plan on more big mods in the future stick with stock size injectors. if you use bigger injectors you will need a custom chip burnt.

 

I know to stick with stock size injectors, I thought they were 22# for the 350 is that right. I am just wondering which of these two does anyone have experience with and which is "better". I was thinking about going with ford 24# and having a custom chip burnt by fastchip, but would rather wait until I do some more mods (cylinder heads, cam, intake, runners).

 

I bought the pink DB9's, they fit well, haven't fired them up yet but should have no problems.

 

Be careful with Ford and GM flow ratings. They rate them differently. Ford 22# injectors actually flow more than GM 22# injectors which might be why you've heard that Ford injectors are "better". Get GM 22# injectors for your setup. Smaller injectors and higher pressure equals better fuel atomization and more efficient burning. For all intensive purposes you have a stock motor and have no need for extra fuel.

 

After re-reading the post if you can afford any down time on your car just pull your injectors, send them to get flow matched, and re-install them with new O-rings. That should cover your problems.
