First of all, I know next to nothing about this, a friend is doing almost all of the work. I gathered all the parts and we jumped into this project today. I have been reading this as though I had a d16a6 where really I only have the d15b7 1.5l and am swaping a d16z6 head. Now I'm hearing things about the z6 distributor having to be modified and all this other stuff. I'm worried as my friend and I don't know anything about the above, and I don't know how many other problems I'll have since it's the d15b7. Does the distributor really have to be modified? What else do I need to know that will be different than the d16a6 swap? My head came with the intake manifold, fuel rail and injectors, FPR, etc etc, and I bought all the new z6 gaskets and timing belt. I know what you're going to say, I should have read up on it more. The thing is I did read up on it and my friend and I were confident. However, that was with a d16a6... *hits self on head*. Maybe I'm just freaking out because my car is in pieces right now.. I don't know. Thanks!!!
