Twin SU Carbs on a L20B, Need help

[Northport Datsun]

I'm trying to assemble my L20B in a 620 Pick Up with a set of twin SU carbs. It's my take on the SSS theme from JDM. Has anyone done this? Does the twin SU Intake Manifold from the A series engine Roadsters fit the L20B head? Does anyone have an intake manifold available? I used Paltech carbs on my 240Z and I am very happy with the performance and reliability of those, so I'm probably going in that direction again. Carbs I can get, but the manifold seems to be harder to come by. Any help is appreciated.

No........there are some intakes available in the classifieds

220 and K14....the latter is the better of the two

Not JDM, which was EFI. The Datsun 810 SSS with carbs was sold in Europe and Australia. It had two su-style Hitachi carburettors.

Will require L16, L18 or L20B manifold. The other engine types manifold will not bolt on.

Why is the K14 Manifold better than the 220?

[ggzilla]

It isn't.

K14 on right....Couple of mins grinding will make it 1.5" to match OE intake gasket

Untouched as per pic

 

 

 

220 is about the same size (1.25") as the Lynx on left

K14 with purple heartwood transitional isolators...38-46........................................................................ :D

Heartwood isolators ... are you from Canada?

Excellent information all, thank you very much. Pictures were great too.

I am with sealik on the K14.  People think it is a "smog" intake but in reality the adjuster screw in between the runners help set the idle and better sync the carbs together.  I can drop my idle all the way down to 500rpm and have it run smooooooth.  Plus as noted above the K14 has larger ports.  

 

Look on ebay if you want them now, may pay more but if you want them they are on there.  I found my on CL for a great price complete, but waited a while.  They are out there though but not as readable available as the carbs.
