Nismo-san

I'm trying to figure out a proper price for an 1990 S5 n/a coupe prepped for auto cross (SCCA solo FP) mods are as follows.....

Stripped interior, racing seat, harness, passenger mounted battery and fire ext. R-teK ecu upgrade (ver1.0). autometer tach and light, oil temp and water temp gauge, nismo steering wheel, pedal covers, removed a/c and heating, toggles for lights, e-fan, and extra lights, battery kill switch, wink 5 panel mirror.

engine is stripped, no emissions, p/s, a/c, airpump, etc, port match intake maifolds, deleted 6port/ vdi not hooked up. 2.5 inch full exhaust,
hks muffler, no cats, grounding kit, additional E-fan, intake, ngk wires, pineapple block plates, mazdatrix aluminum thermostat cover, maqzdaspeed oil cap, OMP REMOVED, 2-stroke only. exedy clutch kit

smoked lights, satin black and flat black two tone paint, gt mirrors, one-off wide stanced wing, front dive planes, intake scoop on hood, aux. driving lights, tinted glass, chopped front bumper.

sport springs (purple unsure of manufacturer, but they handle great), racing beat dtss eliminators, centric cryo rotors, and premium carbon ceramic pads, off brand sport wheels, royal purple gear fluids.

i dont have any pictures available at moment but body looks like a track car body, not banged up, but purpose built, car is street driven and inspected..... (dont ask i know people...haha)

any insight would be appreciated, i know it aint worth alot but i would like some honest thoughts on a price. thanks
