Got a larger photo of the above? I'm interested what was used as an adapter to the carby opening.

^ as am i

[Sprinter86]

i dont have a bigger pic.....

it was actually made from steel tube by boky, it was originaly designed as a turbo pipe for a 4/3k turbo corolla we were going to build, but we gave up and it ended up on my daily sprinter haha.

heres a different angle

^^ very interesting. how is it held on to the carby opening though, by using hose clamps?

was the pcv hose disconnected?

[Sprinter86]

pcv is just open to the air haha no filter.

i removed the 4ac carbie thread thing that holds the factory filter on, and put a 3k on in (much longer) and then i bent it a little, so it actually uses the factory nut to hold the pipe on, hard to explain, so i drew a quick picture..
