I have a d16y8 that i have turbocharged with all the necessary upgrades, including the 450cc injectors. Problem is, the injector bodies are larger (by only a small amount) than the port they are supposed to seat down into. I know about the seal modifications that need to be made, but those will not affect my situation, the metal body will not go down inside the seat where it belongs. I am having strange fuel problems including running rich and low MPG. I think this is because the injectors are not sticking into the plenum far enough so they are not getting a proper dispersion cloud, or spraying right, or whatever you wanna call it...Could it be that i have the wrong injectors???

what do they look like, the regular blue top 450cc DSM injector? I've had no problems with the install on my z6 intake manifold before.

what o-rings are you using? i had to swap out a few different sizes before they would seat in my b18 properly. i think i ended up using b16 ones, the b18s were a little too thick.

i had this same problem, and didnt have time to F with it, i just put them in, and cranked the fuel rail on...Mine does smell like fuel at times. I have a 97 integ with a b18b1, i dont understand what were supposed to dremmel out. The black rubber oring things? I also used the DSM 450's. I'd like to know as well

take a dremel andthe o ring inside the intake manifold and dremel it out until the injector fits in flush...not to loose, not to tight.....Its the easiest thing in the world...easier then installing an intake
