I plan on doing the top feed conversion for spring break. Couple of questions...
1.Will I need a spacer, so the throtle inlet wont hit the new 2200 fuel rail below?
2.I heard Ford Red Tops are good, were do you buy them? I plan on boosting 12psi max, are there other type of injectors for the 2200?
3.What do you do to the ends of the 2.2OHV feed and return ports after the conversion, wont they leak fuel out, or after sitting the injectors, would seal be complete?
4.I plan on adding a 92-96 Corvette LT1 FPR for boost, do I need an adjustable FPR or FMU as well?
"...--[Fuel Rail]--[FPR]--[FMU]--[Return Line]--."..
5. Thanx for your help and inputs.
Yes you need to go to the machine shop and get them to weld or braze in a fitting in that hole for the FPR. I did not use a TB spacer i just modified my throttle bracket.
COMING SOON! VERY NICE!
Do the spacer save your self a headache. I will send you a pic of what i did just let me know your email my way is easy and you dont have to do all that

if he is going with the LT1 adj. FPR then he should NOT get a fitting welded, that would be counter productive.
If you do get the LT1 adj. FPR, then YES you will need some sort of method to increase fuel delivery in reference to boost! (FMU, or doing it electronically)
a boost referenced FPR like the LT1 you're talking about is only going to increase pressure 1:1. You need an FMU to increase it more then that, ie: 7:1, 10:1
OR
'hpt' / standalone
here is a link that helped me decide on what size injectors I wanted:

its a general guideline.
you want to look for bosch injectors, 'red tops' are just a ford thing for identifying sizing.
I found my bosch injectors on Ebay.
IMO its just easier to modify the throttle bracket. And your going to need a fitting put in that hole so you can attach a fuel line to it to run to a FPR, DUH.

Modifing the throttle cable bracket will cause the throttle plate to stick closed. Just because something is easier dosen't mean it's better.

WRONG
the LT1 bolts up to the original position.
what you do with the fuel afterwards is up to you, but theres no need to run a fitting right from the fuel rail
Im talking about if he wants to run an adjustable FPR like an aeromotive or such. Find me one of those that bolts up.

thats not what he was talking about though.
I'm sure aeromotive makes one for the LT1, but whatever, you can splice into the fuel line after the FPR and run that to the FMU.
the LT1 adj. FPR's fit on our rails.

!Viva Aeromotive!
Corvette
Camaro
I can never remember if the 2200 uses the Corvette or Camaro version...
fortune cookie say: better a delay than a disaster
Ok, I looked at Haynes repair book, it looks like this:
Aeromotive 13106 will fir the 2.2OHV 95-97 fule rail/ intake manifold unit (direct bolt on)
Aeromotive 13107 will fit the 2200 OHV fuel rail (direct bolt on)
So if you were to do the top fed conversion, the 13107 would work perfectly, no need for an FMU or additional FPR.
If you were to boost a 2.2 without a top conversion, then the 13106 would be perfect as well, but since your injectors are side fed, boost has to be to a minimum (5psi-8psi avg.)
you say theres 'no need' but is that because you are running HPTuners?
you are going to need a way to increase fuel delivery, and those adj. FPR's will NOT be enough.
