injector questions - sleepless in Seattle

[Stowe, Ted-SEA]

ok, got some injector questions.

I have an 1800 cc, (1798) motor, (77 mgb) 90 hp, saimsed intake ports, I
think the stromberg cd was 
something like 200 cfm but I might be wrong.

I am going to put 2 injectors in it. and an air mass sensor.

the donor efi car used 4 bosch injectors for 2300 cc
according to the data I could find on the web,
the motor (b230f), used a 0 280 150 762 bosch injector. these had fuel
rails,
and are listed as 214 cc per minute, or 21 lbs per hour.
and a chart at www.wolfems.com.au/injector_flow_rates.htm tells me that
these injectors were
good for 42.8 hp each.

 I can't remember the actual rail pressure in their natural environment, (86
240dl). standard bosch jet-jh




so if I scale it up a bit , and for argument's sake use the volume of the
injectors that I have.
(they were all batch fired btw).

I would then need to get 2 injectors that were low impedance, to make them
look like bosch injectors to the ecm, and they would have to have a flow
rate of 428 cc per minute or 42 lbs per hour.

question 1 : does this math sound correct ? I wonder about this because they
were batch fired. this means that they were fired when there was no benefit
to do so, the expended fuel must of gone somewhere. I can't work out the
math in my head to take into account the batch-fired effect.

ok well, I am going to use the msd epoxy injector mounts, I think that these
are made for GM mounting specs. or am I misreading their fuel injection
catalog incorrectly ? it seems that you can use their injectors to replace
gm injectors, if that's the case I'm assuming a gm injector will fit in
their mount. no one that I can tell, makes mounts like this for bosch
injectors, besides the bosch injectors used a fuel rail anyway, I really
liked the flexible fuel hose hardware from msd.
the angles of the injectors would preclude a normal fuel rail.

I can't find an msd injector that does 42 lbs per hour. they jump from 34 to
50 lb/hr.
where would I find a gm parts list that rates stock gm injectors by flow
volume/impedance ?
  
question 2:

or am I digging a hole for myself ? the ecm I have is going to think it's
talking to a specific environment, i.e. stock rail pressure, combined flow
volume etc.

as usual thanks for your expert advice.

Ted
