hi all, recently had an overbored D16z6 intake manifold shipped from the US. had a close look and compared it to my standard Y6 head and found a few differences.


on the front face of the manifold (the large collector cylinder) my std manifold has 2 small and 1 large pipe fitting, where as the overbore one has 1 large, 1 small.

can i use a t-piece on the 2 same sized small ones? surely they both read teh same vacuum?

y6 manifold

on the side of the belt side branch there is a connection, with 2 bolt holes with a hole in the middle, and an electrical plug that goes on, i suspect this is the ecus vacuum sender?

however on the z6 this is not their!

any ideas? or has anybody done it before?

thanks steve
