Oooh, clever! I've got the lid from a Frey-Bentos pie that I am still wanting to put in to blank mine. Still haven't managed to undo the seized nuts though and a little too paranoid to give them too much wellie until I'm closer to someone with welding/drilling/tapping gear
I'd missed that posting at the time.
In fact that is a blatant lie. I was a little tipsy when I saw that post but was paying a lot more attention to the intercooler piccy. I've done a bodge-job with duct-tape and drain-pipe, to unrestrict&relocate the air-intake into the recently fitted HKS filter. I was sure that I'd seen you hole-saw somewhere, in another thread, to do a similar relocation. I was studying the last piccy in that post looking for evidence and completely missed the genius of the drill-hole.
