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.

 

you have to dremal the rings a lil bit.

 

which brand injectors?

 

I am assuming he means dsm's!

 

dremel them out like u said but u have to have some kind of managemet to control the dsm's

 

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
