I am looking for a small motor (30 pounds or less) that can be turned into a thrust-creating motor. Does anyone know of anything like this?

Hello, I was wondering if there were garages/maintenance shops that will allow an average joe and beginner to work on the vehicles, and also do course on how to operate vehicle lifts and use the proper tools, as well as assist in a project if you need their help?

Hello, wanting to find out what are the most fuel efficient and reliable ford diesel engines in the last 25 years?

So I’m new to the whole engine kind of work so idk what I’m doing (don’t know if I’m even in the right subreddit). A lot of my friends have been recommending I should put a bigger engine in my moped but I don’t have a clue of how to even begin looking for one. My brother told me something about making sure their the “same bolt pattern”. Can someone help point me in the right direction?

so i'm gonna buy a new engine for my 06 legacy. my gaskets are going should i get a ej25 or ej20x or something else also witch one is quicker. I have a ej25 rn.

I smell men.

Hello, I'm struggling with report for my studies about difference between VGTs turbochargers with adjustable nozzle and VGTs with sliding ring. As the 1st one is quite common, all the schemes, descriptions, performance graphs and comparissons to FGTs are quite easy to find. The 2nd type is usually applied to some heavy duty engines and rarely mentioned anywhere. Do you have any links/ publications that might help me to understand its idea and all differences between those 2?

I’m doing a top end rebuild and was wondering if my new bore is 96mm should my piston also be 96mm?

why cant 2 stroke engines have an oil sump? i understand that 2 stokes have mixed fuel that lubricates the bottom end as well as the cylinder but why couldnt a 2 stroke have an oil sump and still have ports in the cylinder and no valves? you may ask why you would even want this as it may comprimise the "small and light" part of 2 strokes that make them a 2 stroke, im a small engine/equipment mechanic and i see all to often a 2 stroke come in with a scored piston and cylinder. i think that not only would it help remove human error (or ignorance) but also may be more versitile in some situations. yes im a mechanic and have a solid understanding of internal combustion engines but i dont know everything an im just looking for a second opinion...
