|
|
Anyone having experience of NDIX on 36 hp based engines? Are they possible to jet for a 1300cc engine (69,5 mm crank, WW okrasa heads, 8:1)? I am thinking of using the ones with the 24 mm venturi. But, as they where intended for a 1600 cc engine from the beginning I am worried that there is no jets small enough. |

The zenith was also marketed and sold as a tune-up for the 1200 34/40 hp engine. So the possibilities should be there. Old claudes buggies tuning charts lists jetting for a 1200.
I've bought a zenith/intake carb off ebay for a 36 hp, but haven't tried to see whether it works yet. |

Thanks!
My intention is to use them in a double configuration using manifolds for the Okrasa heads.
Do you have the jetting charts from CB so you can share and do you know the "standard" jetting in those kits? If the intake was a non-plenum I guess the jetting can't be too far off a dual set-up. |

Here is my vintage speed 36er with Zenith carbs. Its a 1558 83x72. Built it and was in the final stages of assembly, then someone called me out of the blue an bought the car I was going to put it in. The car wasn't even for sale at the time. Haven't even fired it up yet. Got me a '56 kombi earlier this summer and thinking of putting it in there. That wasn't my original idea and still don't think it is the right engine for the bus so I am still looking for an early bug to put my engine in. Working kinda ass backwards now huh.

Amazing how close that looks to the 1958 Porsche 356 Engine, The Zenith NDIX 32's were used on.

Finally have been able to get back on this engine. I had sold the car that I planned on putting it in. Picked up a new car last December and about have it road worthy. So I started finishing up this engine to put in the car. I have everything about dialed it so I can brake in the cam, tune it then stuff it in the car. I am looking for some info on the oil filter inline restriction. What is the easiest way to put the restriction in the inlet, and how big is the inner diameter of the inlet fitting after the restriction? Have read some conflicting info. Any help would be great. Thanks |

Thanks for the help guys! Got the engine stuffed into the car, Was able to weld up the 90 inlet fitting and drill the hole for the restriction. Now I just need to wire the car so I can fire the engine. |

OT Alert.
Joshua B, how do you plan on hooking your accelerator cable to the Porsche linkage?
Cheers,

When I fabbed the Porsche linkage to the VW shroud I moved everything to line up the way VW originally had the accelerator cable come into the engine bay. Then I cut and welded a piece of tubing to the rear tin to guide cable up. After that I cut the accelerator cable cable to size and installed one of the cable shortening kits. |

Here are some photos: They are a bit tough to see but it is a tight fit on the install. Before welding on the linkage I tried to dial in the geometry as much as possible. There there is linkage adjustment at the back as well.
I installed the top end while it was on the jack about and not fully connected to the trans. It made it a little easier.
I welded up the oil filter inlet fitting and drilled it our for the restriction. Does this look correct?

Hi Joshua,
Your motor looks great! I've got a 1500cc 36er with the same early Porsche fuel filter. On your install of the fuel lines from the pump what is the diameter and did you need to tap the pump to match the filter which I believe is larger?
Thanks

Thanks! I used the pre Zwitter 8mm split fuel pump. I then used 8mm OD stainless with an 8mm union Tee and had some 8mm banjo fittings tigged to my lines to connect to the carbs. Mocked it all up in copper first to avoid any costly mistakes. The T is a compression fit with hex nuts to tighten. This way if I was a little off or to aid in removal it could be adjusted or removed at the T. Also for trouble shooting, I could easily add a fuel pressure gauge. The banjo fittings were the hardest part to find. You live in Canada so the metric stuff should be way more available.
Hope that helps. |

It looks to me like most everyone is using a behind the fan linkage? I called GB and their 452 says it works with some modification....I would love to see pics of what linkage your using for your Zenith dual carb set up. Thank you in advance. JON _________________ Looking for Sigla sliders
