Kinugawa FC3S turbo oil feed line

[FC Zach]

I was kinda forced to get this, because I just could not get the stock turbo oil feed flange to seal on top of the turbo.
Oil leaking from here drips down the center housing and gets on the turbo exhaust manifold, which then burns and smokes...
Even after multiple attempts with the stock Mazda gasket, I looked for an alternative...

The Kinugawa unit looked good.
But...
* The line is 6" too long - I ended up looping the end that goes into the banjo bolt.
* THIS IS THE BIG ONE: the new banjo bolt does not fit on my 1987 model - the threads were the wrong pitch!
They are advertised for "86-91" models, but be warned!
Luckily, I could reuse the old, original banjo bolt
Make sure you use the new crush washers, which are wider than stock - I.D. is same as stock but O.D. is wider.
Using the stock skinnier crush washers induced a very large oil slick under the car.
The kit comes with a (cheapie) paper gasket for use between turbo and flange, and it works okay.
