How can i get around 200 hp

[King785]

I have a 2001 ford focus zx3 that has been turned into a round track race car for asphalt and i am limited to what i can do to it to get more power..we cant run turbo or nitrous or run sport model motors like the svt motor . The Saturn's r winning all the local races on asphalt and dirt and they laugh at me cause i have a focus.i can handle better than they can but they pull away from me on the straight aways. I have a xcal 3 on they way to help. Does anyone know tricks i can do to gain hp.i am new to the focus.the Saturn's r running two exhaust cams to get more power that's the kind of tricks i need to know.

any help would be greatly appreciated

I can only use stock parts on the outside that can be seen.

It won't be cheap.

200 at the crank or wheels?

What's your budget?

I'm assuming you have a mtx?

Start with an intake, header, and exhaust. Best to buy all this stuff used off an SVT. SVT intake, header, and flex are the best you can get for the car and will look stock unless someone really k ows what to look for on a focus. People are always selling them on the buy sell trade forums for pretty cheap.

With a tune, that should get you maybe 20 extra hp to the wheels for about a grand once you buy everything you need along with the swap.

After that you are looking at cams, shaving the head, and things that cost lots of $$$$.

It's very expensive to get a zetec to 200hp na and in most cases it isn't a streetable car. That's why most people go FI.

I have a gutted cat and 2.5 inch exhaust from the cat and it stops about at the shifter.it is a full race car with a full roll cage and no interior left in it just part of the dash.the head is going to be done as soon as race season is over.i have to be careful on cams because they can cheak them.

I would do a
SVT header , loose the CAT and do a 3 inch Exh
SVT intake with drop in filter
I would remove the head and surface it about .015 to .020 , add a set of stg1 comp cams
Good custom tune , this should add a good 30HP

4.06 final drive for better acceleration
that gutted stock cat doesnt flow well. Get an SVT header (or other long tube) with ORP
15s and low profile tires will help you gear you down further for better acceleration

an SVT intake mani in short runner will help get you slightly more top end

If the head is coming off, invest in 5 angle valve job and deck the head.

+1 on the 15's. Get the lightest wheels you can find too.

If I remember correctly, use 2 zx2 intake cams. Believe they are an upgrade on a focus and I'm sure you could find some fairly cheap. Port your TB and Intake mani. SVT header, lightweight flywheel, short shifter, shaved head. Another trick some zx2 guys use, is changing out gears from other models to help with ratio's. However, I'm not sure if the focus can do the same, but it's worth a look. Remember, it's not only the amount of power you make, but how it's used.

stock parts meaning stock cams right? I would deck the head the 20 over and good valve job... stock parts though would you have to keep the stock valve size? i.e. no larger valves.

Define stock parts? the ZX3 did not have the SVT exhaust as stock so does that count?

SVT brake conversion front and rear will allow for you to brake later.

smaller tires and 4.06 will allow for you to acceleration out of the turn.

Are light weight fly wheels considered bolt-ons? if 4.06 gears would pass I would think the fly wheel would pass... what about a differential?

not knowing the exact what is allowed or what is not it can be hard.

if you hit any substantial speeds things can be done to lower the car and or reduce the air drag a little (wax the car?)... get radical and strip the paint and just polish the raw metal to reduce weight (kind of like american airlines does to save jet fuel). have you removed all the sound deadening material?

ZX2 cams are a downgrade vs stock Focus ones.


I'm woth those who say to pull the head and deck it. But unlike Tom I'd shave a lot more. Just be sure the cooling system is able to handle the extra heat; oil cooler is a very good investment here.
I'll second the 5 angle valve job and cams, though I'd go stg. II or better being you're running a higher rev range than a street car.

Gears also help by multiplying the power you do have. Just the same as reducing tire circumfrence does (the added benifit of smaller tire can also be less wieght).
