i am currently rebuilding my sti 2

and have heard about some sort of oil pump which will is less prone to fail

has anyone got any info on where i could get one

 

Graham Goode Racing do a modified oil pump for the impreza. If you do a search for the STI short block on ebay and then enter their ebay shop you can get them cheaper (from memory approx £160)

hope this help, Paul.
