Drop me a message for a discussion on my experiences of BBR’s aftersales support.
id take my car to Performance Link - they can do you a turbo conversion or cams etc
Of course you would.
Did OP get a price from Dan ST in the end?
Can you do the ITB without cams or do you really need to do the cams as well?
I’ve just had a quote from DanST , there price for parts , itb’'s , cams etc seem reasonable but a drive in drive out quote …..£6000 
Thanks for the update! Kinda what I’d assumed when thinking about doing the same to my NB. For me, at that price, it doesn’t really make much sense given the low value of an NB and the likely marginal gains.
Yeah costly , for my NC , itb £900 , cams £600 and I think around £800 for ECU….then a £6000 drive in drive out ….wow , no thanks
