just like the qustion says will a d15b7 pan fit a y8?

 

i'm going to have to say no with y8 pickup.

 

NOPE. Y8 is AL and won't fit because of the change of the bolt locations. Not to mention the oil pickup.

 

There's a pan depth variance 88-95 depending on whether or not the engine has a fat main girdle. I believe the ZC pan doesn't fit the Z6 or A6, but some(?) of the D15's do.

As for 96+... I dunno, brotha.

 

88-95 pans from zc/a6/b2/z6 whatever are all interchangable, the depth of the windage tray might be a little bit different, but I have swapped so many D-series oil pans you wouldnt beleive, and they all fit. The 96+ OBDII pans (some are even aluminum) will not fit because the oil pump bolt pattern on the bottom side is different.

 

when interchanging the 88-95 oil pans, make sure to use the correct pickup.......

Hate to see a motor starve becauae the pickup was against the bottom of the pan.

 

Hrm.

Without changing pickup, the ZC pan was too shallow on Z6 and hit the pickup. Another Z6 pan fit.

Not my cars, so I guess I should stfu. The only two D-series I've ever owned... one has the OEM oil pan, the other is sitting wrapped in plastic waiting for me to lay it in the car. Not exactly a master

 

if that is the case then what about the oil pump for y8 and z6 same or different?

 

different

 

Never use a obd2 d-series oil pump for longer than 15k miles, they are bullshit.
