Mangolesti inlet manifold

Hi everyone, I am looking for a Mangolesti inlet manifold with or without Webber carbs, 40 or 45 DCOE's
dose anyone know if I can still buy a manifold new or not? I am not in a rush as I am looking to run my Z with a stock motor at first but have a second motor which I am building to give me what I had as a 23 year old.
I would appreciate any pointer as to who may have one or where i may get one. Also I understand there are some members that know exactly what spec Spike Anderson built his samuri's. I would appreciate any help on the spec too.

Many thanks Kenny

Hi Jon, I would like to stay away from the Japanese one as i understand they tend to warp? I would probably go for 40s and a fast road spec, not going to race the car, just want something that is quite quick as it will see me through retirement.

Hi Jon, Just looked at the Harada manifold & it looks quite soldid, have you heard anything about these in respect of warping?

I’ve got two of the Haradas, one for my project and one that’s been on my red Z for several years in use. I’ve never heard of them warping and that seems quite ludicrous to me tbh. They are very nice castings with a good thick flange. They are extremely common and thus well tested in Japan, and have a good linkage that can operate via rod or throttle cable. I would not hesitate to recommend them.

In the 30+ years I've been around these cars I have never, never heard of an inlet manifold - from any manufacturer, regardless of origin - 'warping'.

Same here. Goodness knows what kind of heat pattern would be necessary to warp a casting that was fixed to the head in so many places.

Exhaust manifolds on the other hand...

I pretty much think that the Haradas are the high 'standard'. As you say, its likely they'll be cheaper than the mangolesti Jobbie?

I have a lovely Cannon intake manifold I will sell with linkages. I was keeping it as a spare for my Mangoletsi manifold but I am pretty confident the cannon is a little too long for my application so will sell it.

Here are some detail images of a period Mangoletsi inlet manifold, which was fitted to an "on the list" Samuri Conversions 'Super Samuri' car.

Lots of voids, occlusions and evidence of core shift in the casting. Remnants of the red paint commonly used by Samuri Conversions is still visible in the voids after blasting. They used them like this.

Casting quality - from all suppliers, including Mangoletsi - is much better these days.

It was several years ago, but I got two Haradas for less than one Mangoletsi with the fancy cable setup would cost. I used a Venhill cable kit and implementated a cable throttle that is completely non-invasive (no modifications to the pedal, holes drilled etc.). Lacks the clever adjustability of the Mangoletsi setup, but once you’ve set a throttle cable, all that adjustment is a moot point as you don’t mess with it.

Many thanks Rich, I certainly will keep this as a No1 option. You wouldn't know of anyone that has some DCOE 40's & an exhaust manifold / system

I am sure the quality of aluminum alloy they are using is much more refined

I will think on this offer from you, but like you I believe the cannon ones are about 25mm longer & the ram-pipes are close to the inner wing, am i correct?

Hi Kenny,

I have a set of 40s I’m just about to stick up for sale. Feel free to message me if your interested.
