PVD list the same code (alloy Sparco) for the cally 16v and turbo aswell as the cav 16v but not the cav turbo ? could be just missing from the list but I remember speaking to Pete about it when he had his cav T and IIRC he was looking for one that fitted for his car (and poss to sell).
I'm going there this weekend I'll have a look(if they've got any) , quite fancy one meself.
no worries with the under bonnet fluffy stuff! that went ages ago
the last one i had went round the back of sfi / turbo cover and was just a crap design. that one looks like a good fit. If it fits the cally T then there should be no probs with the cav T - its the same part number for cally & cav 16v.
