Building a custom tube frame car from scratch — meet the Solo.1. This project features a mid-engine turbocharged Hayabusa engine, fully custom chassis design, and a complete DIY car build with no formal training. I’m documenting the entire process step by step, including fabrication, welding, engine setup, and everything I learn along the way. If you're into custom car builds, kit cars, motorcycle engine swaps, or learning how to build a car from scratch, follow along. #cartok #fabrication #haya
