I'm thinking of buying this: ebay item#171975811343.
It will be way too long for the gap you have. And if you cut it down, then you need to roll the lips again so that the joiners will stay on.
I believe using the standard OEM silicone joiner we have to the TB cut down right at the elbow - use a 51mm/2" aluminium straight joiner (I got a short one 76mm/3") to a silicone t-piece adapter (these come with 25mm, 34mm or 38mm "T" for the HKS SSQV adapter to fit into depending on what you have). And you will of course need teh Kinugawa block-off plate for your OEM bov as well
This set-up will not fit with stock intake system and air box due to physical space (the bov will foul on intake cold air feed).
You will need to be running an aftermarket CAI - which you should be anyway if you are upgrading bov.
Total cost: Less than $50 easy.
Pics still to come of actual set-up. I am still waiting for my HKS adapter to arrive
