About Matt's 1986 Corolla 4A-GE

[ About | 4A-G info | Photos | Specs ]

The Corolla Twin Cam's are great little cars. In my opinion the best "bang for your buck".

I bought this car in February 2000. It came stock standard, with 14 inch alloy wheels, and a nice blue velour interior.
It wasn't long before the modifying began.
When I bought the car, the gearbox needed replacing, as it was noisy and crunching in 1st and 2nd gears (worn synchromesh). Instead of rebuilding the standard gearbox, (which is very good and strong), I found an AE101 4A-GZE gearbox through Tony Flood. This gearbox is designed for the (Japanese) super-charged 4A-GZE engine, so it has different gear ratios, and more importantly a viscous coupling Limited Slip Differential (LSD), along with equal length drive shafts. This is a wild gearbox, with a very nice shorter shift, and the diff improves traction on corners. During club events, was also good on takeoff, leaving two marks instead of one!
I've heard lots of stories about how much improvement the Twin-cams get with extractors.
I chose Genie extractors, a 2.25 inch exhaust, with a straight-through muffler. Although I haven't run it on a Dyno, it feels like its gained 15+ KW. The car ran a 16.7 second quarter mile with this setup, (road tyres, full tank of fuel, heavy parcel shelf/speakers, and a toolbox!!)
The stopping power on this car is awesome for a factory system. Not many (smaller) cars these days feature 4 wheel disc brakes. Its a great feature for a little car like this, which I improved even more by replacing the standard front pads with TTE metallic/composite pads.
The next modification of note, was the installation of a K&N panel air filter, and the removal of the pre-air box piping, so there's just the hole on the side of the air box left.
This improved throttle response and induction noise :)
Since then there have been a few more smaller modifications, it's all listed in the specs below.

I have since (reluctantly) sold this car to make way for the AE92 GTi ...
