fuel injectors

whats the pound difference between t1 and t2 injectors? and why would my car spit and sputter after 7 psi?

Injector flow rates and applications; all the below injectors are low impedance, 2.4 ohms.

2.2 Turbo 1 injectors flow 27 pph
2.5 Turbo 1 injectors flow 33 pph
2.2 Turbo 2 injectors flow 33 pph
2.2 Turbo 3 injectors flow 33 pph
2.2 Turbo 4 injectors flow 33 pph
Super 60 Injectors flow 52 pph

got that information from DDG.com

go to Donovan's Dodge Garage

and select from the L side: "Turbo Database" ; read every single link, especially

"40. Injector p.n. application chart and flow rate page "

interesting topic. I just put 88 T2 injectors into my 2.5 minivan (they were cleaner looking) and I am running lean at WOT now. I got this info on minimopar site-

There are three different Turbo I part numbers because the style of the fuel injector and fuel rail changed in 1985 and again in 1988. They actually increased the fuel flow to the early Turbo II engines from 32 lbs/hr to 34.85 lbs/hr. This is equivalent to adding 10psi of fuel pressure! If you have to replace your early Turbo II injectors, you'll probably want an adjustable fuel pressure regulator to lean your mixture back out. While the computer can compensate for the richer mixture during normal throttle operations, the 1987 Turbo II logic module cannot compensate for the richer mixture during cold start and WOT.

So I am wondering if my injectors are 32lbs and this may be causing my weaker vacuum, rough idle, and leaning at WOT. The part # is 4418258 which looks good to me. Maybe the fuel filter is original? Can anyone say for sure if 4418258 and 4418213 injectors flow the same?

Why go stock when you can go big, LOL. I just scored a set of FFV injectors for a good price and they are going on my newly modified T2 setup on a 2.5l, so I will put them in. But I do have a set of early T2 injectors (from a GLHS) and those are what are getting replaced. Never realized they changed the flow on the injectors from the T2's over the years.

I thinkk there is some conflicting info on the 4418258 ; this site claims they are the 33#

DDG- Injector Flow and Application charts


(I dont think there was actually a "34.85#" injector, I am guessing the flow was measured at a different fuel psi and they are 33#)

I have 9 T2 injectors you can have for free. You pay shipping and they're yours. I also have FFV injectors for $50. shipped in U.S. Heres info. on injectors flow rates etc.Stan Weiss' - Electronic Fuel Injector (EFI) Flow Data Table

hey Butch ; I could use a 2 or 3 TIIs (the 33# style) since I think I have a bum injector, plus I wouldnt mind having a spare or 2

No problem, give me an address + I'll send them to you.
