My plan is to leave the stock oil pan unmodified and to cut my subframe and modify it to fit around the 20B pan. really it's just cutting out one section and welding a new cross bar further back... i probably should do this before i re-install the front lower control arms... since i have to swap out subframes anyway...

Either way you do it your gonna have to fabricate. Best to mod the oil pan unless you really know what your doing with the subframe.

Since I moved my engine back 3" I made a custom subframe and oil pan

And if you decide to modify the steering rack mounting in any way make sure you dont have any bump steer with the final product.

i did modify a stock subframe. I simply cut out the rear "cross bar" and replaced it with a smaller bit of square stock. i'll snap some pics while the engine is out for the car to get the bay painted...

so, this past weekend I was able to get the engine test fit again with the modified subframe, depowered steering rack, stock 20B oil pan (with banzai racing oil ban brace), exhaust, trans, and intake setup.

now everything clears a stock hood... without the fancy air box... so i'm running open trumpets and need to figure out filters for them. At this time, the car is stilling with a full drive train except for drive shaft and powerplant frame.

one thing to note are that the header barely touches the subframe so when i pull the engine off and before the car is sent off to get the bay painted, I'll need to do a little massaging of this area. need to just notch it to clear more.

otherwise, i'm happy with the clearance the steering rack has below the engine... and if i wanted about another 1/5'' of clearance from the hood, I could get some 2.4'' tall engine mounts (instead of the 2.6'' I have now) And dropping the engine lower would definitely require me notching for the header on the subframe. I'm also having to look at other options if i want to run a front strut tower bar, the one that came with the car doesn't clear the trumpets.

as before, next steps:
  • engine bay painted
  • header coated
  • massage/notch subframe for header

You know you can't keep using the id lt1_fd3s once this is done, right? I mean
you will now be 3rtr_fd3s or something.

Or just poor!

Looks like progress, anyway you look at it. DGRR 2016 for it?
