Whats a good place to buy a engine
 

i'm looking for a place that has low mileage jdm engines that wont rip me off

try hmotorsonline.com

You can check car-parts.com they list thousands of wrecking yards. You can look nationwide or local depending were you are. I have done business with yards on this site & had very good luck with parts as good or better than advertised. They list prices etc.
