M3 oil pan on m10 block?

[Ian]

A friend of mine has an m10 block and he would like to use an M3 oil pump and oil pan.  Has anyone done this?  I know the M3 pan will bolt to the m10, but will it clear the 2002 subframe?

Not without modification. @M3M3M3 knows.

What I found with an e30/m10 sump, which dimensionally looks very similar: Requires a bit of chopping on the seams of the subframe, which you would want to reinforce. The left hand side is then a cigarettes paper away from the subframe. You could  shave this off the side of the sump and I doubt it would compromise it's sealing ability. With an NK (engine a bit further forward) you couldn't run an ARB, I suspect you'd have the same problem with the 02 engine position. May be an Ireland ARB would fit underneath??

 

All in all a non starter for me.

If it would fit, everyone who does an S14 swap would use it.......

 

so no. M3 oil pan is several inches too long on left side.  this is why the Massive oil pan design basically moves the entire lower oil pan to the right about 3 inches.  and the upper pan has to be chopped also on the left side.

 

below pics of stock pan, and the Massive pan showing the offset.

 

 

here is the massive pan in relation to the subframe.

He had the pan and was wondering if he could use it.
