i got 440cc precision injectors for my b16a3 (94 del sol) and when i went to install them first they are too big to fit in the injector ports. Do i need to find new thinner black rings or what do i do to get them to fit. Then I realized that the connector clip wont fit unless i cut away a small guide in the inside middle of the clip. Did i get the wrong injectors or it this the **** we deal with for not buying rc?
