-- Hi guys (pros)  This (ordinary) guy would like to know ???

Now I have paid a lot of attention.  To what you guys are saying here.
And from time to time you all (almost) make a decision for the best
product.  Since I dont know where to find the end decision after the
matter is close (except in here).  Allow me to ask a question.
http://www.msdignition.com/fuel_7.htm is where you find the Msd fuel
pump at 103US$. There are also a pump calibrator or something like that
for  non-turbo and  turbo and  control box for turbo use only that one
could buy.  The question, do I need the three parts in a turbo
application also do I need the two parts in a non-turbo application or
simply put it the fuel pump alone is alright???

The MSD pump will work fine in conventional EFI system such as Tracy
Crook's system or other car type electronic fuel injection systems
such as the Mega Squirt. If turbo I recommend those type systems
as it is possible to control a waste gate and other devices common
to turbo installations. No calibration of the fuel pump will be
required as these types of EFI systems use a fuel return type of
pressure regulator
