Hmmm
Well a B16 has about 14 hoses for the coolant system, and I can only find Samco selling two hoses for the B16 or B18, and they costs about $130 for just the two. I think they use to do a bigger kit, which was about $370

I got my kit from here: http://www.artelmotorsport.co.uk/display-product.php
You get all 14 hoses and for a great price too! ($180)
