It's a date if you are ever in ATL haha.

I see your example and I will concede that point on volume. I would still beg to question the QA though. Even if HKS, greddy, Tomei jp etc have out source to taiwan etc. There quality has not changed just their manufacturing costs.

Can we say the same about Tomei USA?

I can almost say the same... only because we are equating unknown vendors/suppliers with poor(er) quality.

There's honestly not enough data out there to prove one way or another. Additionally, the part number shift was not done because they wanted to tell everyone the suppliers changed, it was done because they were fighting Japan and wanted to shift products away from what Japan was doing so there was no IP infringement in case they lost a lawsuit.

In any case, when I was at FR I had some high level discussion with Tomei Japan about possibly selling Tomei Japan directly into the US, since they basically were contingency planning. I wasn't around long enough to see this project through, but it was a lot of waiting around.

The amount of politics and behind the back practices in this industry is even crazier than OE corporate politics, but all the consumer sees is the brand. It's why groups like Backshelf on Facebook thrive, because people get glossy-eyed over an old logo and pay absurd amounts of money for it.

Man there's a big difference between sourcing finished camshafts from Taiwan vs. sourcing the blank cast sticks and doing final machining in house. Which Tomei does.
Also, i've seen a lot of people with broken TomeiUSA cams the last couples years. I'd put money on them not being the same exact blanks that go to Tomei Japan.

This is exactly my point.

I trust Tomei Japan based on their track record of quality and very low, if any, failures. Which means I trust them to have the right quality processes in place for their blanks and I trust their machining.

What I don't trust, is a company that is effectively masquerading as another because of the kudos of the trading name. I don't need anything more than that to make my decision, I don't need any further facts. It's dishonest.

I installed the 258 Poncams almost two years ago, haven't blown up yet. Didn't know this was even an issue when I bought them.

Future240

2 years ago it wasn't. this is more recent.

Actually the issue has been around longer, people just didn?t notice anything until Tomei USA started to change part numbers because of a pending lawsuit in Japan.

It’s not that wild of a story to be honest.

I purchased a fuel pressure regulator from them with their gauge also.
Well within a couple hours the rubber boot on the gauge cane loose and fell off and leaked most of the liquid out... very disappointing.

Keep in mind I had a Tomei JAPAN regulator and gauge on my old s13 Sr20 which is still running perfectly till this day! On E85 fuel

So I called TOMEI USA, and spoke with the main guy there.
I told him the issue and he agreed to replace The gauge. He said go ahead and email me with the receipt. I told him I would be willing to drive out 35 minutes to his office to get it.
I get no response email at all complete silence.

During our conversation I told him I was using e
e85 fuel (tuned on that)
He mentioned that his parts are not compatible on E85, I then told him that I have my old s13 is running on that for 6 years on the Tomei parts with NO issues!

He kinda stumbled and again mentioned that his parts are not for use on E85.
I didn’t know at the time that there was a big difference with Tomei Japan and USA (now I know lol)

So I’m thinking that Tomei USA builds cheap parts!

Well, it's not a super drama but it's a point of concern. Much appreciate you sharing your experience.

Glad I ordered all my Tomei parts for my SR build several years ago, that I only just now got around to installing. The turbo's exhaust seal was leaking oil BAD upon install. I'm curious now and want to check part numbers!
