THIS PAGE IS A SMALL PROJECT THAT I DID ONE WEEKEND WHILE BORED(in august 2005 with stock intercoolers).
IT ALL STARTED WITH THE IDEA OF GETTING MORE AIRFLOW THROUGH MY SIDE MOUNT INTERCOOLERS INSTEAD OF HAVING STAGNANT WARM AIR COLLECTING IN MY FRONT END. I STARTED BY CUTTING HOLES IN MY FRONT WHEEL WELLS JUST BEHIND THE INTERCOOLERS(ICs). I GUARDED THE HOLES WITH THE SAME MESH METERIAL THAT YOU SEE IN MY GRILL AREA. ON THE 300ZXs, THE RADIATOR OVERFLOW TANK IS BOLTED RIGHT UP AGAINST THE LEFT IC, LEAVING NO PLACE FOR AIR TO GO MAKING THE IC PRETTY MUCH WORTHLESS. SO I REMOVED THE OVERFLOW TANK LEAVING THE IC OPEN AND CLEAR FOR AIRFLOW.
NOW WHER THE HELL AM I GONNA PUT MY OVERFLOW? THE BATTERY TRAY WOULD BE A GOOD PLACE. SO I REMOVED THE BATTERY FROM THE STOCK LOCATION AND PUT A AFTERMARKET OVERFLOW TANK IN IT'S PLACE. BELOW IS A DRAWN DIAGRAM OF WHERE I PUT THE TANK AND THE OVERFLOW LINE.
THE PINK "X" IS THE OLD OVERFLOW FILLER WAS, THE BLUE LINE IS WHERE THE NEW OVERFLOW LINE IS, AND THE WHITE BOX WITH THE RED DOT IS THE NEW TANK INT'S RELOCATION. I WOULD HAVE USED A PHOTO FOR THIS, BUT IT DIDNT SHOW CLEARLY. SO I MADE THIS CRAPPY PICTURE FROM MICROSOFT PAINT. DONT LAUGH :).
I THEN RELOCATED THE BATTERY TO THE REAR OF THE Z IN A SPOT THAT WOULD LOOK DECENT AS WELL AS DISRIBUTING SOME WEIGHT TO THE REAR WHEELS FOR A BETTER LAUNCH AT THE STRIP. HERE ARE SOME PICS OF THAT PROCESS. THIS IS A PICTURE OF THE LOCATION OF THE BATTERY AND THE PLACEMENT OF THE POSITIVE AND GROUND CABLES.
THESE PICS SHOW THE ROUTING OF BOTH CABLES THROUGH THE FENDER WELL/FIREWALL
I OPTED FOR THE GROUND CABLE TO STREACH THE ENTIRE LENGTH OF THE CHASSIS FOR THE PURPOSE OF A COMPLETE CHASSIS GROUND. I GROUNDED THE CABLE AT EVERY FOOT OR SO AND DID THIS ON BOTH SIDES OF THE Z. I TESTED THE FRAME OF THE Z WITH AN OHMETER AT TONE POINT AT THE FRONT OF THE CAR AND ONE AT THE BACK BEFORE THE GROUNDING WAS DONE AND GOT A READIING OF 57.8. AFTER GROUNDING THE FRAME, I GOT A READING OF 0.50. MEANING THAT THE FRAME IS PERFECTLY AND COMPLETELY GROUND. HERE IS A DIAGRAM OF MY WIREING.
I NO LONGER HAVE A PROBLEM WITH THE LIGHTS DIMMING WHEN AC OR THE STEREO IS TURNED UP.
