How to tell Difference between USDM and JDM 2JZGTE Cams?

[88mkIIIproject]

I have had a set of 2JZGTE cams but I don't know for sure that they are USDM. (the guy I bought them from said they were machined for a 1JZ, they are not, so I can't be sure about where they are from).

They have the 2JT stamp on one, then JZ on the other, and a few other number stamps, and also the small bungs on the sides for cam sensors. Are these only on USDM??..

They are numbered No. 1 and No. 2.

One cam has a small "15" stamped transversely and the other a small "10"

Here are a few pics, thanks for any help.

EDIT: add more pics

the small "10" stamp

the small "15" stamp

How do you know there not machined for a 1jz? They didn't fit? Or did you measure them?

It was, but I did not find out until months later when I tried to install. This was 4-5 years ago.

They did not fit in the areas needing to be machined.

So how can we tell the difference between the US and JDM cams? I have 2 sets in my shed and would like to know.

Do you have a micrometer that you can use to measure the max lift on the two different intake cam lobes?

jdm intake cam is a smaller lobe

Do you know if the intake cam is No.1 or No.2 according to the stamps?

Ok I found my answer. I finally found my micrometer and used this link for reference to measure peak intake cam lift: http://www.turbosupras.com/pages/pages/specifications/JZA80/jza80.htm

Looks like mine are JDM..

91Supra313, I posted a reply in your thread too with this info.

also you can tell the intake cam because it has the two tits for the cam angle sensors
