focus turbo conversion
Hi guys, a mate of mine has a 16. focus and is looking to do a turbo conversion. i suggeted putting a fiesta rs turbo engine in there, he has a 1.8 zetc bottom end and was wondering if you could mate an efi head to the bottom end. hat management would you have to use and hat else ould you need to do the swap?? any ideas as i havnt a clue about focus's
Thanks

for a 1.8 turbo conversion i would look to the focus rs as and example as this is just a 2 litre zetec,
the 1.8 and 2.0 zetec are ssentially the same engine,
first off you need to lower the comp ratio,
http://www.performanceenginecomponen....asp?id=250269
those should help, and will take a good bit of power too,
a set of frs or after market cams for the turbocharging application may prove usefull,
the focus rs exhaust manifold will mate up to the 1.8 zetec head, and you can use the inlet manifold from the frs, the frs has a larger throttle body than the other focus´s, and you will be able to use all the bits available for the focus rs for tweaking some extra power out of your engine, such as intercoolers turbo´s and exhaust systems,
as for a gear box i would look towars sourcing a used frs one or at the very least use the mtx-75 from a 2 litre focus, the IB5 is pants and wont take the power,
and sourcing an frs flywheel so you can use the uprated clutches available would also be a good move.

going to all this trouble of sorcing all this focous rs bit would it not just be alot easyer to carry out a focous rs conversion

does any bod no whats the main diffrence between the two heads or do the use a longer stroke on the 2.0 but dimater would be the same?

Lol @ Chip (think isee what Leigh is saying though)
I think a Unichip would give you your best chance of mapping your 1.8 ecu for boost,
the frs pistons will not fit into a 1.8 block this is due to bore size and i dont beleive it is possible to over bore the 1.8 to suit,
the heads are specific to each engine, the 1.8,2.0 and RS engine all have diferent heads, this shouldnt be too much of a problem, but to be honest the main point you should look at is the gearbox in the 1.8 focus its only the IB5 which is not the strongest by a good way, the 2.0 came with the stronger MTX75 box, and the RS has un uprated version of the MTX75
if i was you id go for a full FRS conversion, so many little things you need to do to get boost ona 1.8 the time and money it will take you are best just going for a full conversion i think,

and as for boxes looked into that two and yes i have got the ib5 box does the mtx75 box mate up to the 1.8 flywheel or would that have to be changed for the 2.0 if that was the case would just got for upgraded and lighter also can get a bc box for the older zetec engines from the gearboxman which comes with a quif lsd two
just after look at the manifolds again i am nearly 100% sure that the focus rs manifold will be a direct fit if i then went for some upgraded pistons and mayb rods upgraded cams focus rs inlet and injectors and then somethink like a Megasquirt ECU and a front mount intercooler would this be enuff for small boost upgrade apart from the box

cheers for clearing some things up would the 2.0 head mate to the 1.8 bottom end or are the the same bottom with jsut diffrent head? and been looking round the pistons for the 1.8 are 85mm and the 2.0 use 86mm so surly could bore the 1mm diffrence out mayb
and as for boxes looked into that two and yes i have got the ib5 box does the mtx75 box mate up to the 1.8 flywheel or would that have to be changed for the 2.0 if that was the case would just got for upgraded and lighter also can get a bc box for the older zetec engines from the gearboxman which comes with a quif lsd two

Second hand focus RS gear boxes seem to be changing hands for circa £500 recently and they come with a Qauiffe ATD diff in them, and also have the benifit or shot peened cogs and revised gear ratios,
Be careful with getting a gearbox from an older zetec as they may have different mounts, for fitment to and escort or mondeo etc, and could need some custom work to get them fitted,
As for the flywheel, im not sure if they will match up or not (i think its smaller), but its a good idea to get the RS flywheel as it will allow you to use the uprated clutches available,
The inlet manifolds are the same on the 1.8, 2.0 and RS engine, all that changes is the throttle body, if youve ever looked at the plastic throttle body on a 1.8 engine then you will see its defo worth upgrading, its the same physical sice as the other ones but the throttle plate is tiny,
the rs exhaust manifold will fit without problem, there are many tubular exhaust manifolds available, from the likes of blueflame, Nortech and Primary Designs,
but i will say it again, it will be easier and simpler to just go for a full rs conversion, and most likely easier on your wallet too,
the standard focus RS engine can see 300 bhp without much work and more than that with a simple turbo upgrade, it has the benifit or forged mahle pistons as standard, the cams are proven to be good right up to nearly 400 bhp,
but if you really are determined to boost the 1.8 go for it, be a good little project,
another thing you could look at is the jackson racing supercharger upgrade if you want boost, might give you enough of a boost to keep you happy,
have aa search on the us ebay should show you what is available and prices etc, they are designed for the 2.0 zetec, but im sure could be used on the 1.8 without much work,

Thge heads are all interchangeable on all the zetec engines, the problem comes from the chamber size, it is different in each head, and can throw the compression ratios out,

as for the pistons looked into them thik ill just get a set of forged or mayb as i dont want mega boost a de-comp plate and read the standed roads are good for over 300 bhp
for manifolds there is some cheap ones from the states for £100 quid but think these will crack easy under pressure can also use adapoter plate and use rs manifold off the older zetec engines
and yes as u say would be better to go for full rs converstion but this is just going be a nice little project to take apart the engine and rebuild it my self to get a nice understanding into the zetec and looking on ebay parts for the 1.8/2.0 turbo converstion are easy avaible
thanks for your help mate

im currently building a 2.1 zetec turbo that will run about 350bhp wen mapped up al in al wiv out having the pectel t2 mapped it would'v cost me about 3 grand (£600 for the map at grove garage, amhed bajoo) not bad at al considering a focus rs engine wiv 212bhp will cost 2.5k-3k.
theres alot involed in it than u mite think so if ur after a simple fix buy a focus rs engine save u the hassle.
my price of 3k is building it myself wiv my best m8 who just happens to builds engine's so the build it self's cost's nothing, if ur not building it ur self then budget a hell of a lot more.

As has already been said, just buy a Focus RS. I'd probably be the first person to say build something that could then call your own, but because of the prices of the MK1 RS you get a hell of a lotta car for pennies!

sorry to jump this thread. Just lookin at options for performance on my 1.8, until i decide if to TC/SC it. Iv got full exhaust/cams mods. Is there a good upgrade to the inlet manifold? Would gettin a bigger TB be worthwhile?

TB not really worth the money for 2-3hp standard inlet is good for upwards of 250bhp so imo not worth changing. is this tc/sc at the min

Would it help if inlet was ported abit to help the airflow?
Wud ST170 inlet fit the 1.8 zetec focus?

yes it wouls fit a 1.8 not worth bothering with inlet. you would need cat for st170 unless you get it modified to fit straight onto a standard type exhaust..

yea it woz inlet. Iv got the st170 manifold/cat fitted already. Iv bin told the st170 inlet is a big job to fit.
Bin offered a 65mm TB and ported std 1.8 inlet to high with airflow for £80 all in and he will help fit it. Is that a bad price?
