#359178 Hello im new here. And I hope im posting on right place. I got eg4 with d15b2 dpfi and im gonna convert it to mpfi. And one of my mate got d16z9 head and he would do me that cheap. So I know lots people do mini me with y8 or z6 head but never heard no one doing with z9 head. I look on internet and cant find much stuff about z9. The stuff I seen saying its the same as z6 just was used on coupes.. but everything the same.. im just wondering ennit. I do have everything of d16z6..i got interior and engine harness... injection, injectors, dizzy, p28 and 4.2.1 exhaust header with o2 sensor.. basically everything less the head.

So would this z9 head do the job?

Thank you and sorry my english :D :D

It is pretty much the same motor, except for a couple of minor specs, so I don't see any reason why it wouldn't work :thumb:
