I have a round port one here thats not being used if interested...Im in Brisbane and am happy to post..

I actually have been using that same picture of the homemade manifold for reference! Yes, HS2 is a vertical pattern but my head is round port. Looks like I'll be building my own.

Looks like HS2 is a 2-bolt vertical pattern?

Lynx D1000 is multi-pattern for Datsun A-engine, but I think no longer made new



Here's a home-made HS2 manifold for Datsun engine, made from stock downdraft manifold

If you have round-port head, the (old) Lynx D1200 fits
If you have oval-port head, the factory Datsun A12T, A12GX or A14T manifolds will work. Only the latter is 4-bolt. All fit 1-1/2" S.U. type carburetors.

Carburetors.com makes a version of each.

Honestly, I know nothing about the Datsun SU manifold but if my (British) HS2 SU carburetors will bolt up to it, somebody please let me know before I cut up my Datsun and my MG manifolds!

I've seen 2-bolt carbs on 4-bolt manifolds using 2 of the bolts, the famous Lynx D1200 manifold was like that. Or is there some other difference that prevents it from working?

I can't use the manifold from Carburetors.com because it is for HS4 SU carburetors; I'll be using HS2.

To smellsofbikes: the engine fits pretty well but there is not enough room for an engine mounted fan, you'll have to fabricate new engine mounts and adjust the length of the driveshaft.

I've never seen a Datsun A-series transmission front seal leak, however the rear seal often does

btw here's the part numbers for the rear engine seal: http://datsun1200.com/modules/mediawi ... php?title=Crankshaft_Seal
There are a bunch of scanned pdf's for the datsun 1200 and datsun b210 online that'll talk you through the rear seal replacement, although it may just be the rear seal on the pan that's shot. Likewise they also talk you through the significantly more intimidating process of rebuilding the 4 speed 56-series trans, or just disassembling it enough to replace the front seal. (You'll want the datsun 1200 manuals specifically, for the transmission repair instructions.)

Quote:Have you considered buying a new one? Even the Datsun factory manifold will accept two genuine S.U. carburetors. Carburetors.com also sell a twin SU manifold.
