OTHER POSSIBLE MODFICATIONS

FUEL PUMP

Fuelmiser Fuel Pumps.

The Performance Intank pump is a direct replacement for the origional pump, and only costs slightly more. Both pumps are internal tank pumps and have a turbine construction.

FRONT BRAKES

The twin piston calipers and larger rotors off the superstrut model will fit onto the macpherson strut models. The excess metal in the mounting backet for the twin piston caliper will need to be machined to fit the macpherson strut hub. Too center the caliper 2mm from the mounting surface will need to be removed. A super-strut rotor will need to be machined from 275mm dia. to 261mm dia. Ensure the center is 55mm as AE111's are 54mm. A custom brake hose will be needed.

I upgraded the race car's front brakes in May 2006. I used Mintex brake pads and new rotors. This made a vast improvement from the previous setup.

ENGINE COOLING

TRD offer higher rate radiator caps and lower temperature thermostats. Most after market parts suppliers can supply an equivelent item off the shelf. I took the standard radiator cap with is 0.9 and replaced it with 1.1 bar one. The thermostat can likewise be changed cheaply and will achieve the same outcome. Tridon also manufacture high-flow thermostats, and this coupled with a lower temperature setoff is the best solution.

INTAKE

The AE101 has a restrictive intake before the airbox which 'pops' up behind the left hand headlight. Removing the plastic piping the factory hole in the airbox fits a 3" flexible pipe perfectly . If a small section of the inner guard is removed from where the resonator goes through the inner guard, a one meter length of 3" pipe will perfectly fit from the airbox to factory hole in the bumper for the FXGT spotlights. The 3" will sit perfectly around this hole, without needing any brackets or ties. I use a K&N panel filter as the factory airbox acts as a cold air box, used in conjuntion with the piping being installed as described above. This enables you can keep the battery under the bonnet.

On the race car, the battery has been relocated and the area where is was and the airbox was has been shielded from the heat in the rest of the engine bay. This enables the use of a K&N pod filter. A 3" dia. intake hose is routed down next to the fan and is tied under the bumper. A small section of the bumper 'skirt' and the plastic underbody under the gearbox was removed also.

IGNITION LEADS

The factory ignition leads have a huge amount of resistance in them, sure this will supress any radio interference but it also robs the engine of power. Champion make leads for the 20 valve but they have not been machined correctly and will "stick" to the plugs, never mind they are better than factory and they have a good warranty. (In my experience, you will break at least one lead when you change the plugs with the Champion leads). I use a set of 7mm leads which I belive are TRD, they are heliecly wound and offer minimal resistance, they have small springs on the ends which go into the distributor cap. I did notice the difference!

IGNITION / SPARK PLUGS

I use NGK Iridium plugs, I find they offer more bang for buck than platnium, and last almost as long. Toyota recommends using platnium plugs always. The rotor has a ruff finish on the electrode, do not sand this off as it is ment to be there!. I looked into getting a MSD Sportscompact ignition, however it was not recommended unless major modfications had been done to the engine.

BATTERY

In crazy car I have a NS70L, light commercial/truck battery, even with the 3" air intake it still fits in the factory location in the front. I only needed to fabricate a new battey braket and lengthen the battery cables slightly. I replaced all the standard battery leads anyhow, and I now have 4 guage earths from the battery to the chassis and engine block. Next is to change the lead from the alternator to the fuse and the fuse to the battery to 4 gauage cable.

In the race car, I have moved the battery to the boot. It is contained in a battery box which is bolted around the chassis rail, and is secured inside the battery box with 2mm metal plates. 4 Gauage cable connects it to a distribution box in the engine bay.
