Car has been a work in progress for a few years now, but finally runs and drives with a turbo and e85.

A swapped supra and an old military vehicle peeking out, cant go wrong here. Is there more build log etc somewhere or clips of this thing out in the wild?

Ha! I started doing a bigger write up, but I’m not as familiar with forum postings, so kept it short and sweet lol. But I do have a ton of photos of progress from start to where it’s at now, as well as a few videos. Are videos even able to make it to the forums?

There is a 5 or 6 picture upload limit per post. 5mb in size. Pretty sure videos can be uploaded, I haven’t tried that yet but if they are on YouTube, then yes. You can use links.

Best advice is to just start small and work up. Next one just start with things like “this is how it came to me” or “this was the first …” and then keep stepping forward. I done such w my build log for my 55’, you can see it for reference. Some have never used forums and others grew up on them. We all start somewhere.
