Intake/Exhaust Manifold Gasket, 79-83 280ZX
|Quantity in Basket:none|
This is the gasket that spans the intake and exhaust manifolds where they mate to the cylinder head. The gasket "shape" above matches what Nissan supplied as a gasket for all 280ZX heads, and is often called "diamond" port because of the exhaust port shape. It can be used with either a "round" exhaust port cylinder head (N47/P79), or a "square" exhaust port cylinder head (P90/P90A). This casting number can be found between the #1 and #2 spark plugs on the bottom edge of the head. If you know your cylinder head number and would prefer a specifically "round" or "square" gasket to match your head instead of the Nissan design, see Related Items below. For an "N47" or "P79" ("round" port exhaust) head, choose part 10-2513. For a "P90" or "P90A" ("square" port exhaust) head, choose part 10-2512. If you are unsure or have a question, just give our sales technicians a call at (800)633-6331.
The 81-83 Turbo Exhaust Manifold has a port shape that matches the gasket pictured above. The Turbo cylinder head has an exhaust port shape that matches the square port gasket (10-2512) in Related Items below. So if you choose the 10-2515 gasket, it will match the "diamond" port exhaust manifold, and still work fine with the square port exhaust head. If you choose the 10-2512 gasket, it will match the "square" shaped cylinder head exhaust ports, and still work ok with the "diamond" shaped port on the exhaust manifold.
