No. A manifold must be fabricated. The cylinder head of the 2.6litre StarQuest was at BEST flowing only about 260cfm. It was made for low end grunt only because of the engine design. That's why you see them being given away for cheap, even the StarQuest guys don't like them..
You'll get low end grunt up to about 4000, then it just heats up. There's no top end in it whatsoever.
