you can cut out that cross support bar that you left untouched. it's not going to be needed and will just be in your way. it's nothing more than an additional transmission brace that would simply hold up the transmission to aid in motor removal. it's not a necessary piece. especially if you need more room for the coolant pieces and/or transmission adaptor section.
also while you're in there you might want to think about doing your frame notches. i mean you're right there.
and i would totally ditch the idea of using the rear stock motor mount brackets. imo they'd be hard pressed to support the weight and torque of the vr.
It def does look like a tight squeeze once the engine is in w/ that cross bar as fas as all my cooling hoses at the thermostat housing. The least I have to cut and weld I feel is better for me. Not saying that it wont work for anyone else b/c you have done wonders A1! As far as frame notches, I would def need help w/ those lol
also keep in mind you can go out side the box on this...i mean you can play around with moving your motor/trans. and personally i'd be leaning towards moving it all further back to gain some additional space. people that have done counterflow 1.8 swaps found them to be very tight against the fuel tank firewall. and granted you are modifying your firewall, but additional room to play around with wouldn't hurt.
go check out some of the vanagon builds for how they did their motor mount setups for some ideas. here's one i know off and am following:
the vanagon guys utilize just the stock rear mounting points but make their own custom cross bar/subframe setup. their stock front transmission mount isn't really more stout or more rigid than a bay trans front mount and they are having no problem holding up to the added abuse of the vr6. this again is also proving my point that you don't need that center cross brace. vanagons never had them.
heck here, check out my friend's cross brace he added into his two frame horns:
you can see he cut open some box tubing and welded it to the frame rails for additional strength. you could do something similar to this in the rear and simply make custom mounting brackets to bolt to the motor.
there's tons of different ways to go about this, but i just don't see that stock rear engine cross bar and mounts dealing to well with the vr6. you're gonna be throwing something that's easily 2 to 3 times heavier back there, not to mention a torque monster compared to the crappy type IV motor.
http://www.brrman.com/bus/ I def liked the design. Running a/c is def going to put me into the arena of running a cradle. Oh welding gods give me the strength. I am done w/ the wiring in how I will be running the motor just have to tape it up once its in the bay to make it look decent. Gonna have to start looking into the 2" square angle and borrowing someones welder lol The only reason I was using the moustache bar is b/c I have seen others run it on the 1.8's and it looked sturdy and clean. Def gonna have to rethink this support all over again. Thanks sauce!
UPDATE: Honey do list has been kicking my butt! Been working in my mind on the bus. Started to mock up a cradle w/ wood. Its looking promising... Baby on Friday so I will be M.I.A. for a few! You stay classy.
UPDATE: A1, I ordered the plate its a 4wk turnaround!
Looking to start stripping and painting the engine area. Paint the block, get the donor car cut and sent to scrap so I can pull the bus in the garage!
UPDATE Thanks to the help of Ivan, donor is cut up and ready for removal! The family went up to the Cod this morning so.... I have a good window for working on the bus!!! Cleaning up the bay some more then coating it! KBS ftw Hopefully I dont run into any issues. Raf stopped by last night and buffed out my door and gotta say it is night and day!!!! Pics to come!
