I will let the pictures do the talking, but this is the most efficient way to handle a VS setup ........ period.
All pressure side piping is 75mm and intake piping to blower is 82mm. 600mm core cooler.
The plenum has had the throttle body put on the other side and also had the tappet covers changed over so you can still put oil in the engine.
There is also an image showing very large extractors fitted on this VS, anyone will know that fitting large bore extractors to an ECOTEC in a VS is near impossible, well this shows it done. Custom headers.
Enjoy and I will grab some images of the finished item as well when that happens
