JDM motor?
hey there guys, im new to the forum, as well as to the honda scene.
im looking to buy a honda civic to race at a stock car track here in King City.
I've herd about the JDM japanease imported motors, and they make more horsepower then the stockers the replace.
Im looking at this one civic, and the guy im dealing with is telling me that its a JDM motor in it, but for some reason i just dont belive him.
are there any physical differences that i could look at, to tell right away is its a JDM?
keep in mind that this car has been tottally stripped, and theres only a motor under the hood... no heater boxes etc...

RE: JDM motor?
Almost right, they all say DOHC. But if the "DOHC" letters are bigger then the "VTEC" letters you have a USDM engine (or valve cover at least). If the "VTEC" letters are bigger then the "DOHC" letters you have a JDM engine.
Someone can always change the valve cover though, so the best way to tell is my looking at the engine code located on the front of the block. All JDM engines have only letter-number-letter and thats it. USDM have a letter-number-letter-number. Just think if there is a number on the end, its USDM if not, its JDM
eg.
B16A1 = USDM (number on end)
B18C = JDM (no number on end)
B18C1 = USDM
B16A = JDM

Here's a list of honda engine codes so you know what motor you're dealing with if you check it out.

thats pretty sick lost i never even thought about that with the vtec letters being bigger than the dohc
B18C = JDM (no number on end)
B18C1 = USDM
B16A = JDM
