My two swiss S30Z Fairlady Restoration build thread

Can't wait to are the finished car!

Some weeks ago i got in contact again with Kris, the guy who bought a few parts from me,  including my first, white S30 Chassis.
He's currently building a crazy Blow-through turbo S30 (more on that when it gets closer to completion) with all tricks and gimmics and a lot of custom fabrication, which includes a custom cast Turbo surge tank. For that reason he once bought some surge tanks from Japan to use as inspiration for his own design. Luckily he doesn't need them anymore, so they were up for sale. And even though i don't need them at all, who am i to turn down an offer on such cool and rare vintage tuning parts? So i went to their garage yesterday and picked up all of this. What a score:

The lot includes a set of 80'ies blow-through surge tanks:

The first one is more commonly know. the SK compe turbo aka Sanyo-kiki Turbo surge tank:

This surge-tank acts as an intake manifold champer to the careburretors with an turbo attached to it. Yes, these where the very first and early turbo kit designs:

Ther second one, which i've never seen before is from the same era, but it's a JKC - Japan King charger surge tank, which was used together with a supercharger.
 

The design is very similar to other brands like HKS, but has those unique fins on it. The basic working principle is slighty different to. the one above uses a kind of "baffle plate" inside, while this one has a cast chamber inside.

Oh and he also had a huge bunch of Carboy and other vintage tuning magazines on hand, which he lend to me. There is a lot of advertizing and information on these turbo and supercharger kits in there. So i will try to complete my post about the different intake manifolds and turbo / supercharger surge tanks for the L6 engine with the latest informatino i got now. Thanks Kris for the Hospitality, and see you soon!

Nice, hadn't seen the JKC one before. My friend runs the HKS type 2 surge tank on his twin turbo set-up.

Thanks. i recently found a load of pictures and ads of ones i haven't seen before. i plan to update my Intake manifold and surge tank post (see link in previous post) with all the new ones, once i scanned them. Probabyl in the next 1-2 weeks.
Need to go through all the carboy magazines first 🙂

I've been crazy busy at work and education, and i'm also working a bit on the big garage / Workshop update and a little refreshing work for the Honda. But more on that soon on this site.
I still managed to get some small things done for the Datsun here and there. Like (finally) ordering those Datsun Mikuni / PHH44 Carb insulators, which showed up a few days ago:

They came from Nissan USA, with a little help from a local chap. Thanks again!

They were once offered under a different partnumber in the option catalogue and i'm not entirely shure they're exactly the same, but they fit perfectly and are OEM nissan items, so i'm perfectly fine with those.

I recently collected a few different Carb insulator setups. mainly  just because i first got the wrong ones, and then some more 🙂


Left to right. Original Datsun PHH44, but for the U-series (Fairlady) Engine, PHH44 L-series replica, PHH40 (L-series) Replica:

The main difference between the U and L-shaped items are a slight offset in the stud position (see left)

What also came in one of those deliveries was a set of NOS rocker arms. Not sure if i will need them, but as you know i can't resist whenever NOS parts get offered:

So my "fun" Motor intake side setup is nearing completion. I meanwhile have enough parts to build one standard and one "sport" motor.

Also just got a call today that a pallette of parts on the way from japan will arrive next week in the Port of Rotterdam, before being delivered to switzerland (Just as the Datsun parts and cars, back in the days)...
So i'm quite excited 🙂

Surprised to see you intend to use that type of rubberised insulator on a six. I don't recall Nissan ever using anything other than the solid, phenolic type insulators on the sixes. 

On the L4 yes, but not L6.

and good luck to pass the inspection in Switzerland. the triples without Veteran status yes. the filters and max 73db no way. At least not in Zurich.

The rubber ones are Nismo and were part of a kit Nissan sold for L6.

'NISMO' is by definition 1984-up. Pretty late L6-wise.

I don't recall Nissan ever supplying them for the L6 until at least (off the top of my head) 1976-ish? That's a long time with the solid phenolic type, which they tended to use on the Works cars by the way.

They have a reputation for moving around too much when they get hot. And on an L6, they get hot. They also de-laminate, crack and otherwise react badly to certain fuel additives. 

Other than that I love them... 😉

If you weren't aware, the U20 Solex carb insulators (16174-25501) have a gasket either side of them, one manifold, one carb. There are also 50mm versions of these.

There's some interesting reading in Bill Fisher and Bob Waar's book:

"how to modify DATSUN 510 610 240Z engines and chassis"

I have a copy from 1973, it's a good read. Here are a few snippets related to isolators for Mikuni/Solex carbs,
