    XCLR8TN's BRG LS6 Build

    My car is a 1991 BRG that originally had all options but an auto tranny. I could go through the various steps of modification that got me to this point (I might later), but I'll keep this to just the V8 build. Car had a Greddy turbo on it before.

    Parts acquired thus far:

    -LS6 engine with 9,000 miles out of an 01 Corvette Z06, no A/C or PS
    -V8 Roadsters subframe mounting kit (includes tubular subframe, engine mounts, tranny crossmember, and frame rail braces)
    -T56 transmission out of a 1999 Trans Am (6 speed), with B&M short shifter and skip-shift eliminator
    -Monster Stage 3 clutch rated to 700 hp/tq (came with tranny)
    -Drive by Wire throttle pedal from a 97-04 Vette
    -Walbro 255
    -Vette Filter/Regulator
    -AN fittings and stainless lines
    -LS1 Pilot Bearing (LS6 won't work)
    -New Clutch Master Cylinder, bleed lines
    -CTS Diff (05, 54k, 3.42 gears and LSD) and diff vent
    -V8R Stage 1 Mounting kit
    -Refreshed Hubs/Wheel bearings courtesy of Planet Miata
    -Sport brakes with R4S pads
    -OEM engine harness converted to standalone by Speartech
    -TAC box to DBW pedal harness (Speartech also)
    -V8R screw-on oil filter oil pan
    -FM V8 Swap Front Sway Bar
    -Racing Beat Endlinks F/R
    -949Racing 6UL's; 15x9 +36 with 225/45/15 Toyo R1Rs


    Parts that I still need for the swap:


    Electrical
    -ECU reflash to delete VATS and 2 of the 4 o2 sensors it is looking for
    -Gauge solution
    -New Miata body wiring harness (mostly just for the lights)

    Exhaust
    -Headers, waiting on Sanderson's 1.625" primary headers
    -Exhaust system (probably custom 3" to a Y" to a single pipe back)

    Other
    -I decided I didn't want my ABS anymore (I had been running it relay-less anyways for about a year), so I yanked everything... which means I need a new non-ABS Master Cylinder (I have Sport brakes to go on) and new brake lines
    -Radiator (more than likely FM)


    Project goals:
    -Shaved (DONE), tucked, and stitch welded (DONE) bay
    -2200-2300lb curb weight (no A/C, PS, Cruise, ABS, heater)

    Random notes:
    -OEM Miata wiring harness with plugs for all options weighed 17lbs.
