I’m still fiddling with bits and pieces to make the Prado a better vehicle.  I have read a lot of forums for high performance Japanese vehicles, where people are fitting these kits.  Some claim a small increase in hp and torque, while most say the kit seems to make the car run just a little better and smoother.

The reasoning behind this is that it’s possible to get high resistance earth joints between body panels and chassis etc., especially as a vehicle gets older.

These high resistance joints cause voltage changes within the electrical system of the car, which can be detremental to all the electronics now used.

A good earth system will eliminate these high resistence areas.  And just remember that when you crank over your motor in the morning, the 200 odd amps the starter motor is drawing, has to find its way back to the negative terminal of the battery, and likewise the 100 watt amp for your stereo.

So I have added 5 earth cables to the Prado.  I used 4 gauge multi strand copper cable with gold plated eyelet terminals and soldered all joints.

• The first cable went from the negative terminal to the inlet manifold.
• The second went from near the throttle body to the firewall.
• The third went from the firewall to the right inside guard.
• The fourth went from the right inside guard to the front radiator support.
• The fifth cable went fron the front radiator support to the negative terminal of the battery.

The only thing I have noticed so far is an increase in idle speed of about 100rpm.  I’ll take it a better run tomorrow and see if there are any other interesting results.

See you out there!

Anyway, the first c

Tip:

Engine Bay Protection<br> Placing a tarp across the front of the 4x4 minimizes water entering the engine bay by creating a bow wave, provided forward momentum is maintained. The result is less water for the radiator fan to spray over the ignition system, less chance of water entering the air intake and less likely for the fan to propel its way up to and through the radiator. Diesel 4x4 's are usually better for water crossings as you do not have the ignition system to worry about. Water in the ignition system usually results in a stalled engine and not actual engine damage, though this is of little comfort when you find yourself stuck in the middle of a crossing. Depending on the water depth, its advisable to climb out of your window rather than open the door and flood your carpets. To minimize stalling from a wet ignition, it's a good idea to spray all the ignition system with water repellent beforehand.
