These are the stuff Bell Engineering did.
1. Motor and transmission. Labor Labor for 17 hours for work done thru Oct. 15, 2008. Uncrated and disassembled motor, drive train, modified engine bay for motor to fit, working on mounting transmission, steering rack and subframe.
2. Modification of subframe. Pulled existing motor out of engine bay and started prep work on the frame rails, removed all mechanical and electrical parts from the engine bay to prep for cleaning and paint.
3. Fabricating initial flat steel flanges for the exhaust manifolds. Tim cut and welded the pieces to cover the frame rails inside the engine bay. Cut the flat bar and tubes to build the rear differential brace which will mount the 350Z diff to the car. Used the factory mount positions and built an I beam to connect the two bushing holders. Finished the other side of the engine bay, tack welded the diff brace together.
4. Hanging the rear differential brace on the car using the factory top bushings. Upper bushings will have to be modified or replaced to allow bolt to stick through the new diff brace. 350 diff is in place under the new brace and measured for additional bracing. The entire rear suspension is going to be pulled off the car to fit the diff as we have to bolt through the rear crossmember and the gas tank is above it. Removed the entire rear suspension subframe assembly from the car. Removed the fuel filter system under the body of the car, a few miscellaneous parts from the underbody and tore down some of the subframe so the diff can be mounted.
5. Disassembling and repairing rear differential; fabricated and welded braces, and painted engine bay.
6. Fabricate jig for turblar K-Member; continued building race for rear differential.
7. Work performed on rear differential reinforcements and mount; changing the mounts on the K member jig to fit the lower pipe around the tabs. Performed welding on the intake manifold. Measurements were taken for cross beams of K-Member and frontal loop.
8. Work performed on threading the vertical rods to hold the diff in place & assembled the diff bracket. Installed the rear diff carrier back on the car. Installed the brake lines, fuel, electric in the rear of the car. Prepped the diff and researched LSD options for rear. Started building the front tubular K member starting with the forward mounting positions and A-Arm mounts.
9. Worked on crossmember and motor mounts, motor mount blocks. Aligned the transmission to differential
