The PD150 definitely fits the 1Z. Says so in the description.
on my car the stock intake was built into the EGR, so to delete it, I had to get the PD150 which is separate and bolts onto the race pipe.
Deleting the EGR has some drawbacks, the main one being slower warm up times which equates to worse average fuel economy, more emissions, etc. I can attest to that. In the summer it's not noticeable but in the winter sometimes I kick myself for deleting it.
That said, I think the advantages outweigh the negatives, at least if you live in a warmer climate. Read the article I linked to and do your own research!
