TBI injector flow ratio

[hirax]

How much is flow ratio (pph) of 2,2ltr TBI stock fuel injector?

what are you trying to do that would require that you know this? Haha, I can't tell you what the flow rate is, but I can tell you if it would be a bad idea or not

For theoretical calculating and compare
I did TBI to MPI and I wanted know, how TBI fuel pump can supply 4x19pph injectors.
Now, after experiments, I know that it cant manage them
MPI injectors needs more pressure at the same flow.

you hit the nail on the head!

Did the TBI to PFI conversion ever get completed? Any more details? I'm interested in doing it. I thought if any of you had any tips on what to do or not do it might be helpful.

I completed this conversion.
Directions from here: http://www.cardomain.com/ride/256160/4
Because I did same time complete engine overhaul, I am not sure it was conversion or overhaul, but now engine run better.
Acceleration - good, but I hoped more
Fuel economy - better, but again I hoped more
My main modifications:
T2 intake and 2,5ltr TB. Tried to use 3.0ltr TB was problems with linkages. Too many make over.
Injectors are Ford 5.0ltr 19pph. At first I tried use Accel 15pph injectors, but they was too small pph, causing stalling on braking and standing on crossings. With 19pph injectors it run little bit rich (O2 sensor: 0.8-0.9) when accelerate, but by constant speed it is ok (about 0.7)
Air cleaner from Chrysler 3.0ltr
Fuel pump Walbro 2.2ltr turbo

That's a cool site! You did some really good work! I wouldn't try it because I love my turbo too much though : D If you're bored, something you may want to try would be switching to a turbo wiring harness and then using D-cal with a turbo computer to really dial everything in. I think you'd get some more power and fuel economy by directly changing the fuel curves that way. Can you get turbo computers in Estonia? Where is Estonia anyways?

Thank you!!

That is so helpful, I have the 89 computer from turbovan & harness. Other parts I have to obtain. Is there other injectors that is suitable for 2.2?

The rest of stuff I need to get is distributor, inline pump (not interested in putting another tank in since Tulip got NEW carb 2.2 gas tank to pass safety).
Yes, Tulip DOES use 2 lines, source and return like other injected cars.
