William's JZA80 Supra

1993 Toyota RZ Supra

"William Writes"

I Bought the car in 2001 as a daily, after moving my black JZA80 on early that year. It was totally stock other then an Apexi Fuel cut defender, boost controller and a front mount intercooler, over time I went down the modding path after I broke the factory turbo's (my first mods were a fuel system to support the new turbo).

Fast forward 10 years after a period of Adulting and personal dramas my goal became different for the car, My quest for a 1000hp 8 second street car started. I originally wanted to achieve this with my HKS t51 kit I had acquired (boy dreams) but it kept falling short so it was time for further upgades and to send it.

1130 hp later we have achieved my 8.8 @160mph pass at drag challenge before we got booted "What a feeling". Future plans are unsure as we have another missile in the build, so this car is kinda on hold for a period while that one progresses. But for now, here is what makes it do it’s thing from school pickup to roll racing and drag events in-between.

I would Like to thank everyone involved over the years as there is way too many to thank but the following have done it time and time again for me.
Special thanks must go to Scott from Next level motorsport for originally helping me get motivated when I was down and out all the time ago and still providing my wiring etc now. Scott Hoffman at Cleveland Exhaust – this car is only as fast as it is from you alone. Mic from Absolute Automotive for helping so many times and ungodly hours and helping me make this car reliable. No mean feat. Geoff Trapnel for machine work on my engines over the last 20 yrs in this car and Brooksy for multiple gear box repairs. Last but not least, Kristian and Naomi @ Goleby's for supplying all the parts for the build. As the plans and the process changed so many times over the years he has always help answer so many dumb questions and recommendation were always on point. Learning to build a monster like this has been entertaining none the less.
