Im looking into buying a focus 2.0 zetec low miles and bolting on a Roush Turbocharger talked to roush today 95 hp to the wheels 110 tq to the wheels. Seems to good to be true just wondering if anyone has any opinion on turbochargers for the focus's cant seem to find any good information on them thanks

Alright you have three choices
You got the Precision turbo kit (http://focus.c-f-m.com/index.asp?PageAction=MFGSEARCH&ManfID=1126&Page=1)

You also have the Roush Turbo (http://www.mcnewsautomotive.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=mcnew&Product_Code=RTKIT&Category_Code=FI)

And maybe the most famous focus turbo it Toms full kit (http://focus-power.com/view.php?showme=Zetec_Kit)

Make sure you know what you're getting. All three are good kits, come with basically everything you need, but they do have different power bands, spool times, use different turbo's, etc. Make sure to weigh in all pros and cons.

Personally, I prefer the Precision kit, because they use a garret water cooled turbo and an "almost" equal-length manifold which will help spool faster than the log style manifolds the other two have.

One last thing, which is what a lot of people forget, is that once you go turbo, premium fuel will be a must, so be ready to start paying 20c per gallon more...and your gas mileage will go down, too...

the roush kit does have a log style manifold, but tom's turbo is a tubular manifold, not log. also, log style manifolds generally cause a quicker spool up, but they don't flow well in the top end, so you lose a bit of HP up top. a tubular equal length manifold will spool up SLIGHTLY slower, but it breathes better for more hp up top.

also, gas mileage going down is not an absolute. it depends on how you drive. if you drive like a normal, sane person, your gas mileage will be quite close to what it is from the factory, just a little less because the turbo actually creates restriction in the exhaust. your gas mileage will go WAY down if you have have a lead foot, cuz you'll be in boost most of the time. as long as you're operating in vacuum, your gas mileage will be SLIGHTLY lower than what it was from the factory. premium fuel is a must though if you want to make decent power

im gunna have to argue the gas milage, oddly you would think more power= more air+more fuel= less gas milage, but since ive had my stg1 kit on the car WITH hitting boost at times i have gotten 300 miles to the tank.

i normally only had 260 with driving nice. i dunno why but thats just how it is for my car so i cant complain... stg1 kit needs an air filter which is like 30 dollars probably. other that that the kit is good to go BUT YOU need to buy tuning. that makes the kit 4k dollars but i like it, and i put good stuff on my car and thats it. not saying the others are bad but the stg1 kit is good for a 13 second pass under the right conditions. im making 200/200 with 9 psi read sig.

ZetecZX3 just put on a roush stg 2 and had it dyno'd and I think he told me he was at 175 hp 185 tq...I hope he speaks up and corrects me

Ray told me a while back that he put a Rousch kit on a car and it pulled 198whp and 201 lbs of tq.....i'm probably off by a FEW. but still pretty decent numbers : )

with turbo applications i have seen proof of better gas mileage with higher average speeds.

Sure, you'll see better gas mileage if you drive the turbo car like you'd drive a stock car. With that much more power, you'll be seeing the redline a lot more often and that's where your tune says to go rich and you're dumping a LOT of fuel in.

There is not performance gains to be had from the water cooled housing , I have a STD turbo on a SVO that has been on there almost 16 years and 85,000 miles and going strong

If watercooling was needed they wouldnt sell turbos with out it

As for the equal length manifold if you are staying under 300HP than there will be no gain in spool time or HP/TQ from anequal length manifold. Now saying that if you want to pick up another 100RPM and spend 1600.00 on a manifold that that can be done

In a lot of cases long equal length manifolds let out or burn up so much heat that it hurts spool time
