The car was modified when we were running it at Bandimere raceway in
Denver it was turning 13.5 1/4 mile times and would have done about
12.5 at sea level. The fuel pump would certainly be a good mod for any
car that has been taken out of it's original configuration or has had
the engine modified. I don't think that a accurate gauge could be
mounted at the injectors because of the pulses but if you place a
pressure gauge in the fuel line it will drop at high rpm at least that
is how we found it. It seems that Subaru gives a pump that is just
enough for the engine and after installing the EJ22t in my '95 Impreza
I installed a 255 lph pump and it showed quite an improvement. And I
am pretty sure that the Legacy Turbo has a different pump than the n/a
version.
