Tomei is not Tomei - Tomei USA vs Tomei Japan - Caution!

Tomei Japan website

I like Tomei parts. They make some of the best hard parts out there.  However, and this is a big however, what you are buying as Tomei parts, may not actually be parts made and authorized by Tomei in Japan.

The more I am seeing and hearing issues about the Tomei USA parts, the more I realize I need to bring it to peoples attention.  Several times recently I have heard about people snapping camshafts in half, and headgaskets pushing water at first startup. 

Just recently my friends at Z-Car Garage had it happen on a customers car. They got what they thought was a Tomei Japan headgasket, and it was a Tomei USA part. The thing never sealed, and it pissed water all out.  Z-Car Garage and Rob are professionals, and have been working on the RB as long as I have. They build race cars, but crappy parts are crappy parts. They didn't even realize there was a difference. Most people don't even realize there is a difference. 

In my 20+ years of dealing with the RB, I have never had a Tomei Japan headgasket issue. Just recently I have heard of at least three people with Tomei USA headgasket issues.

Camshafts, I wrote most of the issues I heard of, to people not paying attention to the down lobes in the camshafts, then loosening them up, or tightening them down wrong. Over the years, I know many people that "had the cam fall off the bench". At least what they told me about a cam that was broken in half. But in the end when I hear its a Tomei USA cam, and it breaks, I have to say its probably a subpar part.
