2 ebay questions (hoods and engines)

[POS carb]

#1. I see "JDM" engines all the time advertised on ebay (http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&tc=photo&rd=1&item=7975607399&category=33615) but they sure as hell look like regular US motors and tere's no way in hell they have 30k miles on them
Is there really a JDM A20 motor and if so can you tell by the serial #


#2. Carbon fiber hoods
what is "A" stock? ARe those the good ones or the ones with defects? I forgot! What is the alternative called, B stock?
A stock is available for $175 on ebay right now (+$200 shipping)

Grade "A" is what you want, no flaws in the cf, and good fit. Mine is a "A" grade, we had to do very little to make it fit with nice gaps at the fenders.
Not sure about those motors.

Stay away from those motors.
most likely they have over 100K miles on them.
you will never find JDM motor with low miles. they abuse them like crazy.
