As title really, ARP only list the D16z and D16y ones, suprised me that there different part numbers though so must be different somehow.

Which should i use on a D16a6? And would they be ok for mini-me later?

Thanks

 

well i've asked this question before and they all said use the z6 one that the companies have
although i havent tried it yet becuase i didn't throw on my turbo yet

 

Interesting ARP said the Z6 ones wouldnt work.
