I have a '90 Legacy 2.2 engine that I need bigger injectors for.  What are my options for cheap higher flow injectors from another Subie.  Looking for about 400 cc/min. 
  
Background:  The engine is being used in a Grassroots Motorsports $2009 Challenge Porsche 914.  I am using a 2.5 shortblock, delta cams, piggyback engine management, and running E85. 
  
Hope this helps.  I just need something that will work, and is cheap (less than $50). 
  
Thanks, 
  
Ryan
