FUEL INJECTOR UPGRADE?

[Jeff Babcock]

Hi,
All of this information about leaky injectors has me thinking about
replacing mine soon. (149K on motor, probably the same on the injectors,
although
they seem to work fine). Is there a sightly higher flow injector
upgrade? The car is a 1986 5K CS TQ sedan. I think the stock injector
number is
0  437  502  032  or also written on there   035  133  551C      The
threads are fine thread. Just trying to find out what other choices and
if the flow rate
is 10%, 15%, 20%......etc. over stock. With all the CIS applications
over the years I would think there would be some choices.
Thanks in advance for help,
Jeff B.
