I had to move the firewall back because the engine is a front sump 1UZ and in order to clear the steering rack on the Maserati, I had to push the engine back 5 inches. So, with that much cutting and rusty floors, I decided to just rebuild the trans tunnel, the floors & the firewall. It took a few days and with no professional tools, I just made it happen. I've built several budget cars in the past and have done several V6 MR2 swaps, so I get along well in the garage, with what I have- it should be fine...
The motor mounts are a mix of the stock Maserati rubber mount plates and the 1UZ's factory mounts.
Very cool! The front sumped 1UZ's always seem to be a PITA to fit; would it have helped your case if you'd had a rear sump?
