Considering buying an engine for a Honda 92 Civic DX Hatchback. I've
done some searching through the JDM market online, and I'm only
slightly confused

Living in Northern Canada so the pickings are slim and shipping is
high! Just looking for something in the 400-700 dollar range, and
hopefully reliable.
Anything I should watch out for? Sites you'd reccomend? Things to be
sure to get in purchasing an engine? Any advice would be great, I'm
terribely new to all this.
Thank you.
