Any gasket (including genuine Nissan ones) will fail if- 1. It is not torqued down securely, and 2. The gasket mating faces are not perfectly flat. The SR20DET is notorious for these nuts working loose, and the escaping gas can quickly wreck gaskets and in extreme conditions the gasket faces too. For best results check that the mating faces are true, and use our unique Kenjutsu Locktab and Locknut kit which will help keep your nuts nipped up nice and tight. Changing this gasket means removing both the manifold and the turbo to get to the rear nuts- so you won't want to do the job twice! We have a large and rapidly expanding range of items for the S-body cars- consumables, performance upgrades, tuning items. Please check out the other items in our shop for brakes, suspension, water pumps, s.
