naw, you'll never get one.

 

CA18DE, SR20DE, KA24DE ... just swap one in and you've got fuel injection too :blink:

How rear are thease heads? I know that i have never seen one, and have never even heard of one beening seen.

[datzenmike]

I've heard they are $12K to $15K rare. Just the head. :D

[Bleach]

They are impossibly rare. Rare in Japan, maybe not even in the USA.

 

Probably at the point where if you buy one, you stick it in a display case as a collector's piece. You don't use them anymore. Not with the number of DOHC engines available today.

the hardcore datsun racer guys get pissed when people talk about z engines with L series heads calling them "Lz22, Lz24 etc...." This is the real LZ

[bonvo]

i would love to have that head and timing set up but the fact that its so rare i would swap a ka in but if it was found cheap i would be all over it

[MAG58]

For all that work, why don't you just put the KA head on the L series (with some machining ;) ) Then you'd have a shorter stroke high winding motor with the KA's nice ports.

 

And the best part?

You can actually find parts for them.

 

Or the MB M111 head fits too.

I think I'm taking a different perspective on this. I'd give my left pinky finger willingly to own one of these heads. Maybe even both pinky fingers! The OS Giken twin cam represents a turn in history. Its also a testament to the innovation and skill of these car enthusiasts who wanted more and had the follow-thru to make it real. The LZ is, in a word, awesome. Fuckthat "put it in a showcase" stuff. I'd give it justice. Mount that bastid on a fresh bottom end and stuff the works in a worthy shell. DRIVE IT! Thats what it was made for. Not talking as a DD, but special events - yes. Flex it every now and again - hells yes.

 

This is probably our Holy Grail. Our arch of the convenant. Our Unicorn.

Doood, It'd look damn sexy in my '59! It has such al Ol skool vibe, with those big nuts on top! Like a flat head 4 cyl Ford.

 

Someone send me one!:D

Just bought an Option Magazine DVD where they drive the Silvia race car with the LZ20 Turbo engine the Nissan/NISMO Festival and that thing hauled some serious ass!
