The T and Tic pump should be the same. The non turbo d24 pump is different in that it doesn't have the afc housing on top. From what I hear, the stock volvo intercoolers are nothing to get excited about, and don't hold much boost. Have you considered using a new intercooler off ebay or something of that nature? They are cheap, and work pretty well I think. Temp differential across my intercooler was a good 75 degrees, and it has held 25psi with no problem.
