Hi,
sorry for my bad english. I´am from germany and have a problem with my nissan z31 (1984) which runs fine for the last 18 years.
Now I ám facing the problem that the shock absorbers are loosing oil. Nissan can not deliver new ones, they are sold out. (Single price per part would have been over 600 Euros)
My car has the absorbers which can be set in 3 stages electrical, that makes it very difficult here in germany to find other solutions. In Germany are only 9 Cars from my modell are running on the streets anymore :-(
Have here anybody experiences with installing Konis, Bilsteins or Tokicos? Do I need adapters or other special parts.
I have ordered Tokicos Illuminas, not built in yet, because they were loosing oil when I received them from the dealer in the usa. Here were a lot of adapters included. Looks like a puzzle.
I would now prefer Koni, but I did not know if it will fit. Koni Germany can give me no correct answer, maybe, maybe not.

Thanks for help.

Best Regards

Frank from Germany

Welcome to NICO!

I'm going to assume we are talking about the fronts as the backs are pretty straight forward.

The strut housing on the adjustable models is different from the strut housing on the non adjustable models. Tokiko sells non adjustables that fit the non adjustable housings and adjustables that fit the adjustable housings, of course they are manually adjusted and won't work with the stock actuators. I have put non adjustables into adjustable housings, I had to mill the gland nut to fit over the end of the strut, I believe the adjustable insert is a tiny bit shorter and might go into a non adjustable housings by simply adding a spacer below the insert. This is speculation based on what I found putting the non adjustable insert into the adjustable housing.

You do have a couple of other choices, first you can swap the entire strut assembly from a car that had non adjustables, this will allow you to run different inserts. You can modify the gland nuts provided to fit your application, or you can modify your strut tube. This sounds worse than it is, a lot of us older Z car guys have been sectioning housings for years to run different application inserts, or even the koni double adjustable race inserts.

...Or call MSA. Zcarparts.com is their website, they specialize in Z cars and I'd be suprised if they don't do international, they can sell you somethign that fits, I know they sell Tokiko as well as KYB but I don't think they sell any koni's other than the classic's. They have great customer service.

The koni rallisport front strut inserts should come with both gland nuts, turbo and non-turbo, but the strut will fit tightly in the non-turbo housing, which is what you want.
