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. Could it be that i have the wrong injectors

 

post a picture of them. Can you read the little plastic part... should say "450" on there with some other stuff.

 

Wow they must be huge injector bodies to not even go into the counterbored area of the intake

 

that's how it is with the y8 mani and 450s. Only half of the injector seal goes down.
It will still work fine.

 

tighten the bolts and fire it up, if it leaks its bad if it doesnt go haul ***
