Re: 4D56 Injectors

Here is a couple pictures of the brass seats and the larger diameter thread that we made to fit these injectors into this head. I have it all back together now and it seems to work fine.

I just replaced the head on a 4D56 engine in a Delica and the injector ports in the new head are significantly larger than the injectors out of the old head. the old ones are about 20mm thread (on the outer cup) and the thread in the new head is about 25 mm. from the people I have talked to, there i...
