Hey Jason
The engine clears the shock towers with no problem. Actually it's a nice looking fit in the engine bay. The first swap started out with a stock non-turbo Buick V6, and I cut off the original motor mount pedestals and fabbed up something to go to the stock Buick mounts. When I went to the GN swap, I made up a new K member (Solved the oil pan clearance problem)
I also made a tranny cross-member and mount. Originally I ran a standard transmission (4 spd, then 5spd.) and then switched to the GN auto. Different versions were made.
Rear end is a chopped Ford 9" with Nissan 280 ZX disk brakes. Fabbed up some adjustable 4 link control arms and panhard bar. I used to run KYB AGX adjustable shocks off a Camaro, but switched to Gas-A-Just's. I also did some mods and run air bags in the coils as well.
Steering had to be changed to front steer rack and pinion. I started out with a std Toyota Tercell rack and then went to a Ford Mustang II power unit.
Front suspension was upgraded to struts/brakes from an 86 Toyota Supra, with adjustable coil-overs and camber plates. I just finished a front brake upgrade going with Infinity Q45 calipers and much bigger disks.
I have had the car for years, so a ton of things have been done to it over the years to get the GN drivetrain to work. Lots of had scratching and frustration. It isn't a swap for the meek. Electrical was a nightmare. (Should have just bought the Caspers harness, but no... I had to do it myself using an old burnt harness. Every single wire was traced, checked, replaced if bad, and then adapted to work with the stock Toyota's wiring.
Fueling was a pain as well. Had to run new lines psi and return from the tank to the engine bay. Ended up cutting open my gas tank and adapting it for a in-tank fuel pump, and bigger lines, as well as welded in some slosh baffles.
