Hi guys,

This time i'm going to refresh The engine of my 280zx as i can predict that the seals and all will fail one time and i want to prevent that (after 42 years !!) 

So, i'm looking for a good (best) engine or headgasket set. (as i already did the crankseals i think i go for a complete head set of seals/gaskets..)

I have found (local in the Netherlands) some brands..

1.  AJUSA (made in spain) makes a set for E89,-

2.  Japanparts  (Made in Japan? sheap junk??) E23,- (!!)

3.  Glaser   (no idea)   E 50,-  

4.  ASHIKA  (Japanese???) E56,-

5.  Payen  (Made in UK.)  E65,-

6.  Blue print  (no idea)  E143,-

So i lean to a set of headgaskets from Ajusa or Ashika,  Has someone the information were NISSAN got his headgaskets for the z or zx from?  

 

Last question is, how thick is a normal (orig Nissan) headgasket? (read something like 1,5 mm?? )

standard gasket is 1.2mm installed. 

I don’t have any experience with those brands, but honestly I haven’t been disappointed with just about any part I received that was made in Japan. 

I have heard it said that "The original gasket (for the ZX) was made by NRZ Nippon Reinz".

However, at some point Nissan changed sources because the last one I bought (from Nissan about a year ago) was made by Stone.
