Throttle Body JDM Style Conversion

Saturday, May 31st, 2008

JDM Supra Throttle Body UpgradeAn excellent upgrade for manual transmission cars is removal of the throttle linkage assembly completely (look at the pics) and replacing it with JDM-style assembly which gets rid of the useless levers and springs. JDM cars being right hand drive never had this linkage, and trust me, the throttle response of the engine without it is so much better, you’d think it’s a different car altogether. JDM Supra Throttle Body UpgradeThe throttle pedal movement is a lot smoother and crispier, it gives you much faster response due to different ratios – it’s like a throttle pulley upgrade for Nissans. It’s one of the best feeling upgrades for the mkIII. It doesn’t give you more power, however power delivery is so much faster, that the car feels much stronger and more responsive.

Supra Pistons vs JE PistonsHere is a photo depicting visual differences between Toyota Supra factory original pistons & connecting rods (on the far right) vs. JE pistons & Eagle rods (on the left). The piston skirt length and design is apparently different, and so is the piston ring thickness and location.

Supra Power Folding Mirrors

Sunday, May 25th, 2008

A set of Supra Japanese Domestic Market (JDM) power folding mirrors was also installed. A control module was mounted in the passenger side door, inside a space already allocated at the factory (much like the space for the power door lock unit on the driver side). Additional wiring was added. Original power mirror switch was also replaced with a JDM unit equipped with a “retract” button. For a complete wiring diagram click here.

Gauge Cluster Backlight Mod

Tuesday, May 20th, 2008

Supra factory backlight tends to be a little yellow-ish. It is especially apparent when using Greddy Gauges. To minimize this effect we used a Green LED upgrade kit. It provides nice and green gauge light perfectly matching Greddy gauges (in this case Boost and Coolant Temperature). For those interested in changing the backlight to blue to match modern CD/mp3 players or gauges, a Blue Kit is also available.

Coil-Over-Plug Ignition Conversion

Thursday, May 15th, 2008

Supra Ignition UpgradeIgnition Coil Conversion. It allows a conversion of stock ignition system from the original factory coil pack and spark plug wires system to Coil Over Plug system without the use of high voltage spark plug wires. The system utilizes original 7MGTE igniter in combination with HKS Twin Power DLI ignition amplifier. Spark plugs are standard.
Supra Ignition Upgrade ITEMS INSTALLED: Polished Aluminum Centre Plate, ground wire and new wiring harness connecting the new coils to the stock igniter wiring harness. The system utilizes six MkIV Toyota Supra Twin Turbo ignition coils. Also, the HKS Twin Power DLI module is used in the kit to provide optimum spark energy which DLI does by controlling the coil dwell time.
