CSC Sports Exhaust

It wasn't easy to find the right exhaust system for my 1600 cc Alfa 105 engine. I prefered the CSC Marmitte steel sport exhaust system from Italy. It fitted exactly to my engine. Here you can see the 4 in 2 manifold. I'd better sprayed it with VHT Manifold Colour from KTS American Parts. What's your experiance with that? Does it really withstand 820°C? The first silencer is competely replaced by a flexibel joint.

The sound is very exciting but not too loud. Increase in performance? - Dont't ask!
I purchased it from Stefan Götzelmann Vintage Alfa Romeo Cars. Nice work!

Stock 1972 GT junior

After driving from 1972 to 1987 in Cagliari, Sardinia, this GT junior came to Germany (Dec. 1st, 1987) and was partially restored. The former owner decided to paint it Ferrari Red Code L300 in 1991.

Alfa GT junior like it looked in June 2003

Later between 1996 and 1998 the engine and gearbox has been dismantled and built up like new. The car was re-immatriculated in Germany on July 30th, 1998. From June 26th, 2003 I continously work on improvements of the car.

GTV 2000 Seats

NOS sets from the later GTV 2000 with contemporary head restraints offer a minimum of safety.
Seat consoles must be adapted to the car by two pairs of sheet metal (ST-37 steel). Geometry differs from vehicle to vehicle. A drawing example see here:

How would a pair of red Schroth ASM autocontrol II safety belts would look like?

6 x 14" ATS Wheels

This is not a success story. Recently I got a set of pretty good looking 6 x 14" ATS wheels for the Alfa 108 mm bolt-hole circle. The wheel offset was ET 38 mm - corresponding to the original Alfa 105 size. 10 mm spacers at the front and 30 mm (!) spacers each side at the rear were no problem.

Tyres were Continental Sport Contact 185/70 R14. These wheels gave the GT junior a distinctive "German Look" of the early seventies. Unfortunately these tires offered a very good ride comfort but no sporty driving properties.

The wheels had a lateral and radial run-out of more than 2 mm. This lead to tremendous vibrations at speeds between 80 an 120 km/h. As a result I graded up to 15" wheels or use the standard 14" steel wheels with inox Alfa hub caps.

MSD Ignition

The MSD 6 Series Ignitions feature a capacitive discharge ignition design. The Alfa stock ignition is an inductive ignition. In an inductive ignition, the coil must store and step up the voltage to maximum strength in between each firing. At higher rpm, since there is less time to charge the coil to full capacity, the voltage falls short of reaching maximum energy which results in a loss of power or top end miss.
The MSD Ignition features a capacitor which is quickly charged (within one millisecond) with 460 - 480 volts and stores it until the ignition is triggered. With the CD design, the voltage sent to the coil is always at full power even at high rpm.

The MSD 6 Series produces multiple sparks for each firing of a plug. The number of multiple sparks that occur decreases as rpm increases, however the spark series always lasts for 20° of crankshaft rotation. Above 3,000 rpm there is simply not enough "time" to fire the spark plug more than once, so there is only one powerful spark.

My MSD 6 is triggered by points. I use the BOSCH distributor # 0 231 110 044 JF4 which has a two stage advance curve with a steep advance gradient below 2000 rpm. Starting o fthe engine has improved very much when using new NGK BP6E plugs instead of Golden Lodges. The MSD control unit is mounted next to the air filter housing.

Cylinder Head Cover

Show and shine again: Polished cylinder head cover replaced the old dull aluminum cover.
Have a look at the aluminum oil catch tank next to the battery improved in appearance with a K&N filter. BTW: There has never been oil in it, so what.

Red silicone ignition cables are a MUST on 105 Alfa engines. :-)

Historic Rallying

This is the result of 2005 and 2006 participation in historic rallying.
  • 3rd place @ MSC Herrenberg "Gäu-Veteranen-Rallye" 2005 (vehicles from 1969 to 1972)
3 Alfas were leading in Mercedes county!
  • 2nd @ MSC Weil der Stadt Rallye 2006

Lamp Covers and Steering Wheel

Rallye look of the old days. I just sewed a pair of protector caps for my 160 mm BOSCH high beams. Special thanks to Boris for the checkered genuine leather he used for the VW bug bra.

And this is the original interior of the Alfa GT 1300 junior (step front) -
the two spoke steering wheel looks a little bit simple and dreary.

My latest mod: Wooden Hellebore flat steering wheel. If you need help to get such a bright, shining surface I recommend Claudio Tescari from Classic Car Parts in Cologne, Germany.

Scuderia Non Originale is a trademark of Gary Williams, Washougal, Washington, USA. Used by permission."

In 2005 I joined as "Director of the German branch".

Gary williams explains it like this:
"SNO was founded by a group of Alfisti in October of 2004, at the annual Concorso Italiano in Monterey, CA. The charter members live in the San Francisco Bay Area, mostly in the region south of San Francisco widely known as Silicon Valley. They include three engineers (Tom Sahines, Richard Lane and Ben Lamprecht), an auto parts manager and former Alfa mechanic (Steve Smith), a former Yahoo web wizard who now works for the government (Ted Williams), and former business owner turned lay-about (Gary Williams).
Cars include several GTV's & GTA's, an assortment of Giuliettas, a Junior Zagato, a Giulietta Spider race car, a Milano Verde, a stunning Turbo Alfetta GTV, and an ever growing list of other Alfas, Panteras, Ferraris, Maseratis, and other Italian makes."

There are only two requirements to belong to this group:
You must be more enamored with Italian cars than is emotionally or financially healthy, and
You must not be offended by fellow enthusiasts who change the wheels on their cars, modify mechanical systems, or make other changes, such as painting their cars non-stock colors.

To Become a Member

1. Reread rules 1 & 2 listed above. By joining SNO, you are acknowledging that you will pay NO dues, attend NO meetings, and will refrain from mocking non-originale Alfas and other Italian sporting machines ... at least not openly.
