Hi Storm_X,

I had the stainless steel plenum (see eBay link below) made up so that you can use the Alfa 75 clamped rubber connectors to connect the plenum runners to the Alfa 75 Twin Spark intake manifold. You can then bolt the Alfa 75 Twin Spark Dellorto throttle body to the plenum.

The rationale behind this was to replace the stock Alfa 75 plenum so that I could fit everything into my GT1300 Junior (stepnose) engine bay without having to modify/widen the engine bay at the driver's side wheel arch. However, I still had to accommodate the monstrous Alfa 75 air flow meter, and get the end of the intake system to a point where I could get cold air into it. As can be seen from the below photo, the pod filter would have been sucking in hot air from around the headers.

At the end of the day, I gave up on retaining the stock Motronic EFI system, and I've converted to twin 40 DCOE Webers... which I like from a period look-and-feel point of view in any case.

I was thinking that the stainless steel plenum would be great if you wanted to turbo charge an Alfa Romeo Nord type engine, perhaps with an aftermarket EFI system... but that's a bit beyond my capabilities and ambitions... so it's up for sale.

Of course, getting the Motronic system to fit would have been easier if I hadn't decided to fit the hanging brake and clutch pedal assembly from an Alfetta (mainly for the dual circuit brake master cylinder and single booster) and the air con compressor you can see bolted to the passenger side front of the Twin Spark engine (mainly so I don't fry on hot Melbourne summer days).

I did also try to find a smaller/more compact alternative to the stock Alfa 75 air flow meter (eg a more modern MAS or MAF device), but getting those to work with the Motronic ECU was just too complicated.

That was quick... just sold the custom intake plenum on eBay.

Ive got a bosch spyder intake manifold (not the plenum) and ive been looking for a plenum to suit turbo. Yours didnt appeal to me so much but i bought one off another car witch has to modified.
