Hey everyone. A friend of mine bought a 92 miata and a new greddy turbo kit. I installed it at the shop I work at, and everything went super great until the oil feed fitting ripped in half... I did some searching on here and looks like lots of others have had the same problem. The thing just kept threading very loose then snapped. Anyways, our fabricator took the bolt that was plugging the hole, drilled it out the same diameter, and then silver welded it to the other half. It has been working great for my friend, but I'm still worried about it. I would feel a lot better if he had a spare one sitting in his glove box. Any ideas on where to get these fittings? Also, I'm doing a custom turbo on my 90 miata and was thinking of using that same feed spot since it's so handy.

Thanks for the help folks! Like I said, I did a search and a lot of people were like "check this link out to answer your question!!!", but then the link was dead.

On another note, at 5.5 psi he put down 141HP at the wheel on a dyno dynamics resistance dyno, so it's running strong.

 

Replace the entire line with something more common. Do a search and you'll find the necessary parts. I went with banjo fittings and -3AN line.

Wow thanks. That was fast

 

Whats the set up on your friends car?

 

well it's a 92 with 90,000kms on it. Greddy Turbo kit, Magnaflow catalytic converter, and Magnaflow stainless catback exhaust. It runs very strong.
