Hello all! I figured I should post somewhere to document my builds and issues and how I fixed them for me to look back on and hopefully someone else to help use to keep their car alive when I run into silly issues. For some background I have been building/tuning small motors and race bikes for about a year, then moved to a MZ3 and now am on the mazdaspeed platform due to an accident in that car. I am trying to research as much as I can and learn 
I am studying mechanical engineering with a hope to get into the automotive field.
My 2007 Mazda Speed 3:
I bought this car for 5100 in July of 2025 with 153k miles, I had a throttle body go out on me, and then the connector went out(expensive fix at the dealership to figure out I wired the new pigtail in wrong), then my clutch master cylinder went out, and the in September I blew the engine at 156k miles(Oil pump chain skipped a tooth and I spun a rod bearing). I swapped the engine myself with one out of a cx7 from japan imported through JDM Seattle with about 50k miles on it. Now I am at about 158k miles and have started tuning myself with Versatuner. As this tuning process goes on I will update, post logs, and try to explain what I am doing for yall to judge me(hopefully while being told why im wrong)!
