Identification of TC inlet manifold

Post by Graham Stewart » Tue Feb 08, 2011 9:45 pm

Hello Guy,

I wonder if I could trouble you to identify an inlet manifold that has been offered to me. I am looking for a manifold to suit a Lancia Beta Spyder 2 litre engine to which I intend to fit twin DCOE 45 Webers. This engine/carb combination requires a specific inlet manifold to suit the inclination of the Beta engine and I am hopeful (although not entirely sure) that this is the one I am looking for. Can you confirm or deny? My apologies for the slightly fuzzy photographs; these were supplied by the seller.

Many thanks,

Graham

No that will not work on the Beta with 20 deg engine tilt, it would need an angled adapter plate. It is the Mangoletsi Fiat 131/124 one.

Thanks very much for the quick response Guy, even if it was not really what I wanted to hear. To be honest I rather thought it was the 131/124 Fiat item, but was hoping it wasn't. I'm aware that adapter plates can be made up to convert these manifolds to Beta usage, but am pondering the advisability of doing that. I would have two concerns with adapting the 131/124 manifold;

1) Wouldn't the adapter plate add to the overall depth of the manifold compared to a 'proper' Beta one, and cause under-bonnet space complications with carbs and air filters?

2) Would the adapter plate compromise optimal flow through the manifold, again compared to the 'proper' Beta one? If so, how far away from optimum is it likely to be?

To which I'll add a 3rd question - are the Beta variants of this manifold still available (and I think I know the answer to that one, as well...) ?

Many thanks,

Graham

I have no GC Mbeta stock, sorry. I have the patterns but have not madeany for ages, they just sit on the shelf for years..

There are no problems with using the adapter setup all all. The adapter has to be drilled to bolt to the head and threaded to accept the 131 manifold. The adapter of course has to be fettled to allow a smooth transition from runner to port though. I would have round holes machined thru and then modify them.

Sure!

If you get someone to make an alloy plate (basically a 15-20deg wedge) I can give you the head and manifold mounting dims.

I am regrettably having to avoid making some stuff lately due to pressure of admin & doing quite a lot of heads & engines really.

Thanks for your kind offer, Guy. I may need to take you up on that. Eric Weston has advised me that Richard at Great British Sports Cars (aka Robin Hood) may be able to do this for me; I believe Eric has had something similar made up in the past. I'm hoping to speak to Richard early next week and will keep you posted.

Thanks again,

Graham

Graham,

I do have a GC sidedraft Beta manifold that I'd be willing to trade for a GC Fiat manifold.
I hope it's not inappropriate to post this here...

Hi Csaba,

This sounds a perfect match, although I hasten to add that my manifold is a Mangoletsi item, not a GC one. I'll continue this conversation by PM, rather than in open forum. Hope this is OK, Guy.
