In this one I’m getting the rebuilt 2JZ back in the mix and going over what went wrong the last time around. When you’re building MK4 Supra stuff in your own garage, it’s never just “throw it together and send it”—it’s checking every little thing that can bite you later: assembly details, clearances, sealing, and the kind of small mistakes that turn into big problems once you start leaning on it. I walk you through the mindset I use when something doesn’t add up on a fresh motor: don’t guess, don’t blame parts right away—verify. If you’re doing a 2JZ rebuild (especially with a turbo setup and plans for real power), the takeaway is simple: take your time, double-check your work, and be honest about what failed so you don’t repeat it. This is the behind-the-scenes reality of MK4 Supra builds—fixing the issues, learning from it, and getting the car back to a point where I can actually trust it before I start making pulls again.
