1991 Toyota MR2 Turbo K24 Swap

The story

Got it as a gift from my dad in 2018, had the stock 5sfe that we slapped a turbo on. Lasted not very long. In 2020 at gridlife midwest fest I made up my mind to put a k24 in it. Over that winter I built a jdm k24, sourced a e153 toyota trans, and put together what I was hoping to be a 450whp car that I didn't have to worry about rebuilding. Took until 2023 to get it running, using a full standalone haltech elite ecu on pump 93, i made 460. Meanwhile I fixed up the body work and painted it millenium green, got bespoke built trd alumi k wheels that fit over the wilwood big brake kit and got as close as I could to how the specs came from factory. At that point I was craving a little more hp so I switched to a flex fuel system and turned up the boost. Now it makes 525whp and its so much fun. Constant upgrades including a custom wiring harness I made myself, switching to a dbw system, and now im just doing maintence, cleaning, and enjoying the car.
