OK im new to the forum so this might not be the right section, there is no build forum area . i just though i should do a build diary on this... im building a lamborghini murcielago LP640 replica. my base is a 85 fiero 2m4. well first i pulled all the body off, then the doors, then the interior, dash, air box, ect. then i pulled the entire wire harness out..... then pulled the whole suspension, brakes, cradles,ect. the only thing left was just the frame and tub. i then took it to my shop where we stretched the frame 10.5 inches. sheet metal on the gap, and did a very clean stretch job to it. i stretched the cradle once i made a jig for it on the following day. poly bushings on the whole front and rear. i did the beretta brake upgrade for the front, and just got new calipers for the rear. i painted the springs and calipers orange to match the body. now i had to choose gauges....... there are so many out there. the closest i could get was in a junk yard where there lied a t boned 06 grand prix GT. so in order for these gauges to work i needed the wire harness out of the car, so i pulled the entire harness out of the car gauges, air box, a/c controls, hud center, steering column, fuse box, bcm, pcm, gas pedal, brake pedal, door harnesses, window motor, all the switches, radio, everything. now the steering column all i had to do is fab a bracket to mount it up. and push the u joint out the top connector and swap the steering shaft with the fiero shaft, pressed it back in so now i have the fiero steering shaft with the GP yoke to bolt to the steering comlumn. i have the aluminum dash brace with the air box mounted out of the GP and im trimming it to fit tomorrow. now i know this sounds way to much but its not just the gauges. now i have a 06 grand prix just in a fiero. i get the new climate control and a/c controls. gauges, a working hud unit, on star, air bags, and i have absolutly zero conversion to put my 06 drive by wire series 3 supercharged 3800 in,,,, i just plug it all in. also i now will have all diagnostics on the car. all CELs will be legit. im in the middle of trying to get the comp g tapshift to go into my car.... so how many fiero based lambos do you see with tap shift (paddle shifters) and the fastest way to ruin a good replica is old gauges and a/c controls. but i will get pics up of everything once my wife gets her damn camera. but i figured i would share my ideas.... for everyone wanting to do a 3800 this is the best way although it is a whole lot of work but ill keep everyone updated....thanks
