| Corolla 4A-GE 20 Valve |
|
The 20 VALVE 4AG was the latest and last version of the very popular engine series. This engine replaced the 4AGZ, and showed the world that at least in Japan and some world markets- the Toyota TwinCam legacy was alive. Of course, it was also a natural to install this powerunit into the last generation Corolla RWD. The engine had to be reoriented to RWD configuration and the firewall modified to clear the distributor. (There are other options in setting up the ignition and fuel injection system, that can make for a tidier install, but the plan on this project was to use as much factory spec parts as possible.) Suspension is set with TRD springs, adjustable shocks, and suspension bushings- in keeping with the factory original theme. In fact TRD Japan has set-up a car exactly like this- with some mods on the ECU and camshafts. Panasport 15X7 are used with Yokohama Grand Prix M7R, 205/45-15 tires. Custom headers (in the same configuration of similar RWD 4Ags) with an HKS Dragger (a special HKS import by Toysport) finish this Japanese Spec set-up. The last new 5AG HKS kit (with ultra-lightweight Toysport 20-Valve pistons) and full internal upgrades is planned for this project- making this the ultimate naturally aspirated Corolla in the U.S. This is a work in progress as we wait upgrading the body panels into the latest version of the Corolla RWD model from Japan. A work in progress.
