i own a 83 280zx and for the last year its been garaged while i rebuilt the engine, so far the whole bottem ends been done with a custem lighter flywheel but what i want to know is if there are any DOHC cylinder heads off later model Z's or nissans that will bolt on because in the future im planning to put on a stock twin turbo set up that i pulled off a smashed skyline for $800 and i would rather the two vavles of a DOHC. So far i've had to look at getting an engineer to build a custom head wich is a little expensive any suggestions please

 

L28 has got two valves...one intake one exhaust.

There was no factory DOHC models for the L28 though there is a rare LY28 or something that is dohc but they are rare

Personally the cylinder head off the l28 is great for turbo charging..hence the L28ET.

Though a cross flow head would be nice..

Have a look into Toyota Cressida heads partically the 5ME and 5MGE..might be differnt but who knows.

 

thanx ill look into it
and buy the way i ment two valves each for inlet and outlet

 

There was not an L28 DOHC - that motor was an L20, 2.0 inline 6...reved nicely, but very low on pwoer.

Only company that did a DOHC head was OS Giken in Japan, price when it was new was around $11k.......very very rare, and no longer made.
