no dirt cheap way to increase power in a modern engine. Rechip it the first step Contact dealers to find price & availability.

Stroke and bore it. Swap heads. Beef up the valve train. Replace the pistons and rods. Use a crankshaft that has been checked and found to be free of flaws.
Change the ECM to allow a higher RPM level.
Or
Just get a Ford engine and swap it out.

there may be some aftermarket parts, but it depends on where you live...............in some States, the engine can't be modified
