Injector on the left is a 550cc high flowed jobbie, purchased ages ago with the intention of going into my coupe. Injector on the right is a stock EJ20G 380cc unit.
I had previously sat the injector in the rail and it seemed OK, however I'd not tried to fit them because I knew the rest of the fuel system wouldn't keep up. I've just gone to fit them and the little caps wouldn't push down over them, and at this point I put them side by side. Quite a few differences.
Can anyone tell me how I can fit these in? Perhaps by fitting later model / aftermarket fuel rails? More to the point, can someone tell me what they'd be from? The guy said something about being the full 550cc from a JDM STi, but I thought the yellow tops were 440cc?
