Up to this point you’ve seen me tear down, tear apart, strip, cut, beat, weld, and paint my Miata to prepare the car for its new Chevrolet Performance LS3/T56 Magnum six-speed drivetrain. Now that we are done test fitting and modifying things, reassembly can begin. The work is going to happen quickly from here on out, so hang on!

After reacquainting myself with parts that have been stashed away for months, I began reassembly with the brake system, chassis wiring harness, and interior carpet.  I then bolted a new Hurst Shifter on the T56 Magnum, installed the fuel system to feed our hungry LS3, and bolted on the frame rails and transmission crossmember for good.

This may be the most exciting part of the build, ‘cause everything we do from here on out gets us much closer to firing this monster up for the first time!

Reinstalling the wiring harness was made much easier by referencing photos I took months ago with the smartphone. Isn’t technology great?
