VGS intake fitted with 3x Weber IDF carbs info.

[bmw.rasse]

Hello!
My name is Rasmus and i´m from sweden.
new at this forum, and i haf to say very nice!

to the problem.
Last year i bought my self an e21 fitted with a VGS intake manifold and 3x WEBER IDF carbs.

I have asked for information about the intake here in sweden but couldnt get any.

i have gathered some information but if they are correct i dont know.

That there where a colloboration beetween Alpina and VGS, to create these intake for german hill climb e21s, can this be correct?
And that there where only thirteen intakes that where made. the company was called something like VGS racing or VGS preformance.
I sent alpina an email for some information, ill hope to hear from them.

AND i hope somebody can help me at this forum!

Here is a pic of my set and another one i found on an U.S forum.



Thanks!

Hi, they look lovely.

I know VGS did a limited number of inlet manifolds for m10 engines but have no idea about m20. Good luck with your search though.

Thanks!
I can guarantee that they sound lovely!

I think its odd that not one does know anything about the intake.
it is so frustating to search for something and not finding it!

I havent heard anything from alpina yet.

sorry for my English

VGS (viktor günther Sport if i remember correctly) was a tuning company specialized in fitting weber carbs on cars (especially porsches) . they fitted Downdraft webers to 320/6 because of the 323i order times were long back in 1978 and the costumer wanted similar power output (+/- 145 HP). I think they collaborated with MK-Motorsport and Erang who had similar Webert-kits. http://www.vgs-motorsport.de/

Gunter / VGS (Germany)

Importer for Germany of Weber carburetors, Viktor Gunter has made tuning kits for most popular cars of the seventies. Among them could not miss the 3 Series: the kit was addressed specifically to M60 320 and included the installation of three twin-choke Weber 40 IDF carburetors. With a compression ratio of 9,3:1, saliva, so the power to 135 HP @ 6600 rpm / min, with a torque of 160 Nm @ 4500. Completed setting up the structure with Koni shock absorbers, which lowered the car 2 inches in front and 3 behind; tires remained as standard, mounted on lightweight BBS alloy wheels with 6-inch channel. No changes in the brake system. For the body, Gunter did not suggest anything specific, merely mounting a front spoiler Kamei production.
The price of the kit was (at the end of 1978) of 2000 marks, to which they were added in 1000 for the other structure. Adding these figures to the price of a new 320 M60, one could buy a 323rd series, which gave the same performance with the advantage of the availability of a couple more: the kit is therefore addressed to those who already owned a 320 and M60 wanted better performance without having to change cars.
At the end of 1979, Gunter has produced and marketed under the brand VGS (Viktor Gunter Sports) another kit for the 320 M60, more powerful, giving 150 bhp @ 6800 rev / min., While the maximum torque of 171 was @ 5500 nm.
The performance was slightly better than those offered by the 323rd series, but the economic aspect was always tipped the scales in favor of the latter, that for the same brands of equipment costing less than about 2000. It is really strange, given the links with the Italian Gunter Weber, that his kits have been sold in our country, where they met with good success with those who wanted the performance of the 323rd, but were not willing to pay ' exorbitant tax of 35/38%.

The M60 320 Gunter developed in the test car's Sport in November 1978. In the box, the battery of three twin-choke Weber carburetors.

Erang

This company in Tier marketed in 1978 an upgrade kit for the M60 320 in collaboration with Viktor Gunter, importer for Germany of Weber carburetors.
Almost completely analogous to kits Gunter / VGS, manteveva the compression ratio of series (9,2:1) and provided for the mounting of three carburettors double body Weber 40 IDF. The power went up to 142 hp @ 6600 rpm / min, with a torque of 160 Nm @ 4500. Completed setting up the low ride, the tires remained as standard, mounted on light alloy rims with Alpina pass 6 inches, while the braking system remained the standard. As for the bodywork, Erang mounted a production Kamei front spoiler and side stripes very similar to those of Alpine, with the inscription "Trier Erang Tuning" instead of "Alpine".
The price of the kit was (at the end of 1978) of 3000 marks, circles and trim including: one 320 323rd Erang cost so as a standard, which gave the same performance with the advantage of a couple more: even the kit Erang, as well as his counterparts Gunter / VGS, then turned to those who already owned a 320 and M60 wanted better performance without having to change cars.

I don't know of any numbers, but i've seen 2 VGS carb kits and one e21 with these carbs on ebay
I don't think they colaborated with alpina because Alpina didn't sell such conversions.

on ebay. I saw a fully restored set buy it now price for 1000 Euro. a non restored set went away for about 750 Euro. pretty expesive

[bmw.rasse]

I have never seen a kit before, now i haven't had an e21 that long. but i got 5 bmws and I'm only 21 years old!

so there can't be so many kits still left.

i gave about 1300euro for the whole car

But i don't think I'm going to sell the kit.
thinking of building a nicer engine, and a nicer suspension setup.

oh, and some photo's I collected earlier!

love this topic- great set-up
sounds as though someone is re-inventing the wheel here
see:
"Webcon have just produced a CNC- machined all alloy intake manifold to enable throttle bodies or triple Weber DCOE carbs to your M20 6 cylindar engine= 2.3 -2.5 cc
see: www.webcon.co.uk
part no MM2161 or better:
