If your in open loop it doesnt mean your ECU has been messed with or that your ECU is bad , something as simple as a bad 02 sensor can cause your ECU to go open loop The cam position sensor isnt what tells the injectors to fire , the cam position sensor doesnt have be hooked up ( non VCT ) for the engine to run perfectly fine What ECU are you running , if stock do you have or know any one with a SCT XCAL3 or XCAL4 ? If you do I will be happy to look over some logs for you When was your front o2 sensor changed last , for an over fueling / fueling / misfire issue that would be the first thing I would check/log Tom

You should never use Alum retainers , back in the day 50`s - 60`s it was all there was , now days you have steel and titanium on top of that the stock Retainers to Titanium is such a small difference that it isnt worth the cost If you do choose to go with the duratec I would do the 2.3 vs the 2.0 , you also have the 2.5 Tom

Let me give you a little back ground of my self , I have built more SVT Focus engine that any living person , I have tuned more SVT Focus then any living person , I have turbocharged more SVT Focus then any living person , I have made more aftermarket parts for the SVT Focus then any living person , I have made over 550HP to the wheels with a SVT Focus , I own a SVT Focus that makes 326 HP and 331 TQ to the wheels with the original all stock Ford engine that came in it Saying all that one of the parts that I made was a VCT Eliminator which eliminates the VCT gear and removes the VCT Solenoid , when you do this if what you were saying about the VCT is there for better mid range TQ and HP you would loose that mid range TQ and HP , When going to the VCT Eliminator and regular gears there is no loss of TQ or HP anywhere from 2500 to 7500 I have spent untold Hrs playing with the phase part of the VCT in the tuning software on my in house dynojet dyno and could never make any more TQ or HP by changing it The VCT on the SVT is there for emissions , nothing more , this is no opinion this is proven fact ! As for the interference Engines , many Toyotas , dozens of the Honda , many many Dodges , Mazda , Mitsu , Nissan , I own an engine machine shop as well and we have had 1000`s of engines come through for bent valves Tom

Actually the VCT is there for emissions and does nothing for performance anywhere , if you remove it and go to adjustable cam gears you will see no loss or gain from removing the VCT , there can be some idle issues from the larger cams the SVT has stock There are dozens of interference engine in the US with and with out belts Tom

Correct the Focus SVT / ST170 makes 170 rated and buts down about 145-151 to the wheels on a dyno I have many of the SVT / ST170 engine parts if anyone needs them Tom

I have seen both stock ECU and aftermarket , if stock keep the knock sensor , if not I am sure there not using a quality enough ECU to support a knock sensor and remove it If you shoot me a picture of the ECU I can tell you if it is stock or not Tom

I have tested both pumps for the Duratec , I didnt see any higher psi and when I tested for volume I didnt see a gain , why they call it high output I dont know Yes they are made for the Turbo Duratecs I dont use them because they cost a little more , most shops install them either because they dont test to see what they actually do or to charge more for the job Use the stock pump and you will be fine , if your going to go over 7400 RPM go to a dry sump there are some nice ones out there for the Duratec I also agree with the rule of thumb of 10psi per every 1000 RPM but thats for oil psi not to get confused with oil Volume Tom

Yes the black piece with the 2 wires is the knock sensor , if your running the stock Ford ECU this is a must to use , if your using a aftermarked ECU then your timing is a best guess The knock sensor from the Ford Focus is extremely accurate , why kit builders use any other ECU then stock is beyond me Which ECU do you have ? Tom

Yes it is Tom

Not a problem , if you have left over parts you want to sell let me know , you need to get a wide band air fuel gauge , HG dont just blow you need to check things , can you barrow a SCT xcal and I will look over a datalog for you Tom

You are correct the SVT Focus is all on its own , it isnt really classes as a " Zetec " The SVT has CVT on the cam , Duel Runner intake manifold , Oil squirters in the block , higher compression , SVT head is totally different as well as cams I have tuned and built a LOT of these engine both in 7`s and SVT Foci , there is very little done to the SVT Focus engine to put it into a Caterham I wouldnt call them rare you just have to know where to look for them , I might be interested in all your old engine parts Let me know if you need any help and I would change the timing belt on your new engine , if it brakes you will bend all the valves Tom

Please understand I wasnt implying anything , I just had never seen that to be an issue with the billet gears and there is 20+ dyno runs between the 2 posted dynos I am always open to learning new things so I ask questions Tom

Got a link to it ? I do a lot of Focus stuff and may be interested in the brackets and SC , I can make my own piping and IC to fit the Focus I am also tuning the MK3 Focus now and there is nothing out for it yet being it is duratec this may work on it Tom

Odd , your saying those 2 dyno pulls are 100% the same with no changes other then the oil pump gears I have built about 10 SVT engines with the billet gears and I have my own inhouse dynojet dyno and I have never seen any difference and I plug the oil squirters in the SVT engine so I should have more oil psi then you have unless your doing your clearances tighter I would like to see the datalogs of those 2 runs , I think there is more going on other then what the dyno is showing , what tuning software are you using ? Tom

I also feel the stock Harmonic Balancer should always be used on any Zetec thats used for performance use , I feel the rubber there takes some of the harmonics out of the rotating mass Tom

http://www.tts-performance.co.uk/#!ford-duratec-/c1amx This may have been posted already but didnt find it , good looking power adder Tom

I thin you will regret using that brand gasket , the only one I have found that holds and works is the Ford HG for the Zetec or SVT and I have tried them all with building over 400 Zetec / SVT Focus engines I also found that going over and TQ the ARP studs with the ARP lube about 8 times and I do not re torque them when hot and never have any issues Tom

I know of about 10 oil pumps that the gears have broke , The max I tune rev limiter for on the Zetec or SVT is 7350RPM with stock gears and 7650 with billet gears I know of one set of the C-F-M billet gears that broke on a boosted engine and he turns it to 7800+ and is making over 500HP to the wheels I like mobile one synthetic oil and I still use it , you are correct in the most bearing ware comes from the first 10-30 sec of the engine running , spinning the engine over till you see oil psi before starting helps a little but it wont help as much as a accusump will Tom

I cannot say enough on how important I feel a accusump is needed with any engine with a oil cooler , I wouldnt have a performance car with out one and I dont Tom

I am located in North Carolina , I have tuned emerald before and have a DynoJet Tom

I am all for the stock ECU , there faster , uses the stock knock sensor which you cant get on a standalone for less then about 4500-6000.00 , mass air etc , I dont like standalones most are archaic and 20 years behind on what they offer Stock ECU and SCT where I can is what I like best , I can tune about any software tho , I have about 30 downloaded on my tuning laptop Tom

1) position/placement of the intercooler (either turbo or SC) ****I do agree this would be the biggest challenge , I like a challenge LOL 2) position of the turbo and its interference with the steering shaft on left hand steered cars ****Same as above 3) is the ECU capable of handling a turbo environment ? **** Load vs RPM that's all a ECU cares about basically if it will tune your engine NA then there should be no issues tuning it with boost , change the MAF or MAP , Injectors and start tuning 4) is the radiator big enough to handle the extra heat developed by extra hp ? ****If your tune is right you should not have any issues with the added HP over heating the engine unless you shooting for over 400HP for extended times 5) is the powertrain able to handle the extra hp without reliability problems ? That is a question I cannot answer yet , I would think they could take 300 to the wheels with no issues , I wouldnt go dumping the clutch but most guys I know with these cars have a good bit of common sense meaning not a lot of kids own them , more ??? seasoned lol 6) will the gear ratios be adequate for road courses to allow the turbo to spool up so the power band is in line with the need ? **** Yes I wouldnt go changing the gearing The stock Zetec will lay down 250HP to the wheels with boost all day long to go past that # you need to do a built short block Eagle rods Forged pistons ARP head and main studs That is quite a bit to overcome but I don't think it's impossible. I do think it will be expensive. Is it cost effective ? Not sure, depends on how much one wants the extra hp. __________________ **** It would be costly but adding a turbo to anything is costly , I cant see it being more the adding one to a Focus and tuning it .... Agree whats another 100-200+ to the wheels in TQ/HP worth ????? Tom

Its good I understood what you ment and agree , I have seen some real butcher jobs when it comes to adding turbos to things Tom

This may be the case in some you have seen , I make all my own piping , manifolds , intercoolers ,tuning etc , I made the turbo kits for the Focus and almost every Focus kit worth having has copied my design over the years , I wouldnt do it and put my name with it if it looked like crap I think there is room for everything needed and to look factory , they now have turbos that do not need oil return lines so the turbos have more options as to where they can go , intercoolers are far more efficient so they dont need to be hugh any more But thats my opinion lol Tom

I am a turbo guy as you can tell by my name and well known in the Focus world (723HP 2000 Focus daily driver / 326 HP SVT Focus on the all stock engine)and use to be in the SVO Mustang world , I have turbocharged everything from a bar stool cart to a 572 Cu. In. Big block 55 Chevy I love turbos , I dont agree that they over power a car , I do believe they can over power a driver and common sense has to be used and you would have to change your driving style other then that turbocharged cars make great track cars , I have run all my Foci at VIR and a few other tracks and love them You hear you cant get through the apex , turbos take to long to spool (turbo lag) 15 years ago a lot of this had some merit , not today Superchargers have no place in a 2.0l Zetec engine in my opinion there vampire sucking TQ eating monsters that leave you wanting vs a turbocharger I dont care if its a 1000 LB car TQ is the name of the game and when you learn how to drive it and 90% of the people out there can a turbo on your 7 done right will be leaving you wanting nothing but more boost Tom
