A 5.4 4v isn't seen every day. Lol
It's got a ford forged crank, before they switched to the cast ones, Mahle pistons and forged I beams but I forgot what brand because I build the block a couple years ago.

I have stage 3 ported c heads and a ported boss 260 intake too. I'm thinking of making it a short runner.

2005zx4thewin Adjustable cam gears allow you to shift your power band either direction, u could add a cam kit to really widen your powerband, along with shorty headers and full exhuast, with a short ram or cold air intake, you could really do work on your powerband as far as tweaking goes

malinowski The engine is a 2 liter 4 banger, low to mid-range torque is gonna be hard to come by. I really don't know much about this engine but I would assume that the most torque you'll pull out of it at usable RPMs could come from a supercharger or stroking/boring the engine.

If you put a supercharger on the engine, it would have a good increase in torque and horsepower throughout the entire powerband, but especially more-so at lower RPMs (compared to a turbocharger or N/A mods).

If you were to bore or stroke the engine, you would increase the displacement, so the engine would go from a 2.0 liter to, say, 2.3 liters. If the Focus puts out 159hp and 146tq at 2000cc stock, or 79.5hp/L and 73tq/L, you could assume that another 300ccs would boost those numbers to 183hp and 168tq. Those numbers are definitely just predictions. But still, a theoretical extra 22 ft lbs of torque would be helpful and would most definitely be felt at the low and mid-range.

My advice for right now-- wait for others to lay the foundation for mods and prove the reliability of them.

The time spent making it isn't worth the gains you'd get from it. Lengthening the intake runners with a phenolic spacer, you could fab this using a gasket to match the ports, would likely be a better option. Until someone tries it, we'll never know.

Makes a nifty paperweight tho!

I saw a guy with a similar setup and a more restrictive intake put down 700 with a 76 mm turbo. I'll probably eventually go that route, it's just not in the works until I get my business started. I'd like to get 900 to the wheels when I do though.

JL330 Tb = throttle body. It's just a spacer between the throttle body and intake, I honestly don't see it being too beneficial. Shorty header is an exhaust mod, it goes before your catback and bolts to the head. I haven't seen any testing done on these with our cars though. It's all speculation at this point, none of us really have a clue what these things are capable of, especially with stock internals. We'll see more go fast goodies when the warranties start expiring.
