I just stumbled across this news today.  5th may release date.

Brilliant, thanks for posting Jason! I am still trying to decide between the Fujitsubo or spirit garage twin system (real shame Sean doesn't do a twin with his sport/race).. though I am not sure I can justify the extra $1k over the Fujitsubo (especially on what is going to remain a pretty stock l24)

Now knowing the release date, I can put it on the backburner for a couple of months

First of all, I would say that the description "Nissan factory race header" is kind of misleading. It would more accurately be described - in my opinion - as a 'Nissan Sports Option' or 'Nissan Race Option' part, or - if it was being retailed in the USA by 'Datsun Competition' - as a 'Datsun Comp.' part. 

The 'Sports Option' parts......... were designed and manufactured with the intention of sale to the general public, had full part numbers and a pricing structure, were listed in factory-authorised literature and customers could seek advice on their fitment and use....(and) were - in comparison - volume produced, and in different facilities.

Your Street-Sport item will be based on one of the 'Sports Option'/Datsun Competition retail items.

 

Ok, so the words 'fatcory' and 'works' are to be avoided so as not to confuse - thanks.

 

So where, please, does this manifold fit in the scheme of things which the Spots-Option header appears to emulate ? Noted in the catalogue, is this another or the same customer option part ?

Isn't Eiji's system a Fujitsubo brought in  then ?

Never a twin exhaust line - I believe that they were conceived for small cc, high-revving engines and that even stock export engines outgrew them.

Datsun Spirit and Spirit Garage are not the same place, one is a well regarded garage in Japan that make a twin pipe exhaust system, lots of other parts, has a great reputation.

The other isn't any of the above!

You don't need to avoid them completely. Just use them correctly...

You see the bits that say "FOR CROSS FLOW" and "When using a cross-flow type of cylinder head...."? 

The 14004-N3120 MANIFOLD-EXHAUST is for the 'LY'/'Cross-flow' cylinder head. It was a Nissan Sports/Race Option part. It only fits the 'LY' 'head.

Just as with the normal L-gata exhaust manifolds, the true 'Works' exhaust manifolds for the 'LY' heads were quite different from the 'Sports/Race Option' parts.

Here's an example of a proper Works race exhaust manifold for an LY Crossflow engined Z:

....as you can see, it differs in shape and construction from the 14004-N3120 in the Sports/Race Option catalogue. That's the difference between 'Works' and 'Sports/Race Option'.

I see thanks - and also round-ports ! Those are large diameter primary pipes - 44 minimum internal ?
