At first I was pissed they didn't include the right amount of copper washers, but this is just.. I can't even... (this is the oil supply bolt that goes to the turbo)




Note: This would be pretty good for a bb turbo, but on a jb its asking for trouble, never had a problem with kinugawa parts until I received this.

can you explain what I'm looking at, for the "uninitiated"?

It is the bolt that feeds oil to the turbo, the one on the right is oem and feeds more oil to the turbo, while the bolt on the left acts a restrictor and feeds less oil than the oem bolt. On journal bearing turbos that need lots of oil lubrication, this would starve the turbo of oil and overheat and damage the turbo.

the one of the left has a small oil hole, prob .030/.025. The one on the right obviously has a bigger opening for more oil to flow through. Ball bearing turbos use the type of restrictions on the left, while journal bearing turbos use the type on the right.

thank you. that sucks.

Jeez that sucks. Did you catch it before damage occurred or did this really destroy $5000 worth of your car? Sorry if it did. I feel your pain!

Caught it as I was putting the coolant and oil lines on my turbo. This is a good example why parts should be inspected before they are installed.

good find. I am about to install a new kit on mine so that advice will be put in affect

Wonder if that's a once off or common error... could be the cause of the failures reported?

Glad you caught it. Always helps to do an extra check on every aftermarket part.

good catch. definately check every part, especially aftermarket ones, before you install them on your car. I have had issues with brake line banjo bolts, suspension bushings, and a few other stuff so I always check everything. Welcome to the world of aftermarket parts.

Why the heck would you use kinugawa brand anyway?
Your over complicating a bolt lol!
Napa and everyone else stocks these for cheap

Haha while that may be the case with the bolt, I ended up buying a 9 install kit for 30 bucks, hard to beat that price while kinugawa's quality is good enough for simple coolant and oil lines.

This is why its good to overview your work and double check for stuff like this! Gladly you caught it man!
