Would billet compressor wheels for volvo k24 work on porsche k24's? Ard and kinugawa offer stock sized wheels that seem to have great reviews with the volvo crowd.

Need bigger than that to make a difference, also they are flank milled which is the cheap way of machining a billet compressor wheel. Point milled compressors have 3rd order geometry, more efficient. This pic should help illustrate. Those guys are making out like a bandit selling those for 200$. Likely be better off with a 18g or 20g wheel which is cheaper and lighter anyway.
