I can't find the mod with the engine I had

I had my installation all good to go and then I had a situation involving data lose. I found most of my mods that I used on my previous install, however I got stuck on one thing. I had found a mod with a "Racing Engine" for the Wentward 35' (or whichever one is the stock one), and I cannot find the mod for it. The name of the engine was Racing Engine and it ran on gas. The mod was on the beam.ng repo. Thank you!

 

It's either that the author took the mod down entirely, or it is outdated and not available in the parts selection to show up.
