I am working to swap an ecotec into a Mercedes 190e. I have it so it almost fits. So close.
I switched to this type of oil pan and trimmed the fins back.
I still need 1-2" for it to fit, over the subframe and steering arms. so I am thinking of cutting into the front subframe, I have trimmed the "lip" where the two stamped pieces come together. But still is too big.
what is the best way to do this? Just cut it down to where I need it, and then box it back in at the lower hight with the same thickness of steel?

Can you get a view showing the crossmember looking at it from the transmission tunnel? Then mark up where you want to cut?
Without having that, I think your plan sounds reasonable as of now.
Instead of just boxing it back in, when i did the miata i cut a few pieces of 1x1 square tube. Plug welded through the existing crossmember at a ludicrous number of places, stitch welded them together, etc. Pretty much tried to make a honeycomb or steel inside the sectioned crossmember.
Tack weld some sort or bracing/reinforcement so that when you cut out part of the crossmember, it doesn't spring into some weird new location. It's surprising the stresses that are in a component. Remove when done.
If you can cut it out smooth, you may be able to flip it over and weld it back in.

Pics? Can't reeally picture it
Good advice from all. Thanks.
I will try to get some better pictures later this week.
before I cut the top back I will try to weld some angle iron on the bottom.

I like this idea. Do you recall what thickness of metal you used?
As far as pictures, i haven't found any yet. Still looking, but not hopeful at this point. It was 1x1, about 1/8 wall if i remember correctly. Sorry, its been a few years.
