This swap will share quite a bit with Daryl M's LFX build, although he is several steps ahead of me as well as having much more free time to work on it than I....

Just getting into this by testing vertical clearances last night into the cradle after removal of the coolant base oil cooler and to see if the stock front mount bracket needs to be 86'd...

Did some initial vertical sizing up of the LF3/F40 combo last night...

What a great swap! I will be watching with great interest. What version of F40 are you using?

Looks like a fun swap!

Does the oil pan have an oil pan?
I also noticed we have the same tastes in harbor freight floor jacks!

Yeah..the pan has a pan...real PITA since I can't set the motor down on concrete to level it with the cradle without crushing it....

Does the center axle shaft bearing carrier line up with the F40? What is the carrier from?

The carrier bearing bracket is from the same Saab 9-3 turbo v6 or LP1 which is more or less the same block as ours.. For the LFX it should bolt up perfectly to the block, as was my ASSumption for the LF3, however on the LF3 the leftmost bolt hole in the bracket lands right on the turbo oil drain tube flange. I had to cut off the third mount hole to get it mated for axle alignment etc...

The stock lf3/xts bracket does not work nor does any other carrier bracket from an automatic AFAIK.

Debating on building a lower support bracket for the Saab bracket or cutting up the xts bracket and building a plate steel adapter to the block. Leaning toward the Saab bracket as everything lines up great now just need additional support.

Fyi, I tried a gmc Acadia motor mount carrier combo mount and although it bolts up the alignment once again is for an automatic.

Also, using the beefy cobalt turbo axles to handle the power this should produce....just have to swap out the axle stubs first

I used the blocks from the giant Jenga game I made for the grandkids out of 2x4s . worked great to block the motor/tranny in place. I also made a custom dolly for the cradle out of scrap steel to role the thing under the car.

I am sure you have some old Fiero sway bar links sitting around somewhere. Cut about 6 or 8 of them flush with the secondary pan and get longer oil pan bolts. Make some stands that protrude slightly below the pan. Weld some 1 x 1/8" bar between them to help stabilize them if needed.
