Evening people

I know this has been done in the past so anyone who has done this i would be really gratefully if you can reply, but what parts time cost etc do i need to make my st170 a turbo version


cheers guys n thanks in advance for your replys

 

PM Simon170 mate or wait till he sees this thread. AFAIK he has the only turbo ST170 in Europe not sure if the yanks have turbo'd the SVT although they probably have. Not cheap put it that way. Same principle as turbo'ing a zetec but a bit more involved management wise with the dual length runners and VVT.

 

PM sent

 

cheers for the info matey. THink I know what im gonna start doing lol

 

saving up lol

 

ermmm for about 2 months or so pmsl

 

i did have one, till i sold it and the new owner blew it up,

had omex 600 on it and disabled the vct, had a spec list somewhere

 

Not good mate

Is it worth while doing the conversion....

 

we had a few issues with the guy that built the engine, it then went to another company to finish the build off and put omex on it, because of that and the owner not listening to good advice that was the reasons it didnt last that long. hindsight is a wonderful thing

the head on the st170 is a good piece of kit, with a little work it is miles better then a standard zetec head but if you are going to do a lot of work on it i personaly would say go for a normal zetec lump

just found a spec list here, iirc it was the first st turbo in the uk

Engine: 2.1l 4 Cylinder, 16v, ST170 Duratec block and head. Fully Ported, polished and skimmed head, with oversized valves. Ones off Cams made to Ray Mason Engineering’s spec. Cosworth racing made to order pistons, Arrow steel con rods, lightened and shot peened crank shaft. One off inlet manifold, made off ST170 inlet mated to a Escort Cosworth plenum, with fail rail for 8 injectors. Garrett T25 water-cooled turbo, with Focus RS water cooled intercooler. Focus RS engine loom and ECU with Omex 700 engine management.

Gearbox: Uprated MTX75 5 speed box, with Fast road AP racing clutch and Quaife automatic biasing differential with uprated driveshafts.

 

What sort of power did that produce?

 

cheers fella ive been talking to simon170 on here about it....
Thinking of which way to buy the kit at the minute... Credit card, save up and buy the kit, or but a new part month by monthn and run both cars at the same time..

Simon suggested the basic parts that I would need are as follows

intake manifold
exhaust manifold
turbo
intercooler
management
breather system
exhaust
fuel pump
injectors
stage 3 clutch
solid flywheel

where would you recoment buy all the parts if i was gonna do it month by month, pumaspeed, burton power etc

cheers matey

 

I wouldn't buy from places like there you will end up spending an absolute FORTUNE. All those parts need to be suitable though so you need to sit down and think what power you want, how much you want to over engineer things, how much money you will need to spend and also whether parts will work together. You could take a bunch of things from a Focus RS for example. It may be a good idea since you are in Essex to speak to a tuner like Grove Garage perhaps (I can't think off anyone off the top of my head who is hot on zetecs around there right now) and go through it with someone who knows what they are doing and will have some experience in this sort of thing. Simon would be a good person to talk to in regards to most things but some things are best discussed with a good tuner who has experience on the engine itself, knowledge of parts and can come to some solution.

 

Cheers mate. Wheres grove garage??? Im not so much worried about the cost side of it. Ideally id like to see around 250+bhp Main thing is the focus will still be as reliable as it is now Im just looking threw a few sites at prices at the min that simon sent me

cheers matey

 

all pretty standard fair for a turbo engine really, the devil is in the detail i.e what spec and make, as simon has done it recently i would imagine he knows what works better with what, when i done it it was very new back then and a lot of it was trials and tests. (done it what 7 8 years ago now?).

month by month is fine if you are going to horde the stuff until you have everything and give it to your builder. as said above i hope you have deep pockets if you want to use those companies, i dont know what pumabuilds prices are like but they have done some work on focus in the past.

where abouts in essex are you out of interest

heres a pic of the inlet we made up





i hope some pf'ers can see something familar lol

 

Im from romford mate. Prob wont go with those guys but Im new to the ford scene so need to know of a few companies that deal with turbo conversions etc

You in essex as well mate

 

Not far from me, im over in Collier

 

What is this likely to cost? And what is the st worth?

Would you be better selling the car and taking the lump of money to buy an FRS?

 

or sell the st engine and put a frs engine in it

 

they are all different options i have in mind. Really want to keep the st170 engine and put a t25 turbo on it. Few people have suggested about going the supercharged route, whats your views guys

turbo or supercharger (not worried about the cost tho)

cheers

 

Probably easier to turbo to be honest. Supercharger conversions whilst less involved parts are harder to source. Got a wider scope for a turbo conversion. And I think perhaps a T25 will be too small a turbo to use. Better off going for a GT series or at the very minimum roller bearing T3.

 

Fair point m8 so thats
turbo 1 supercharger 0

pmsl cheers for the input on it tho mate always helpful

I wonder why they used such a baby turbo? Seems a lot of work to carry out to then limit the power with such a small turbo unit....how did the car drive?......I would have thought the engine and its efficiency would overwhelm the turbo?

 

cheers mark

 

it did mate, oringal plan was a t30 hybrid, but as above problems with the engine builder forced a rushed build in the end, wasnt done as i wanted it, had just broken a frs for spares and used that turbo. drove nice though made 280bhp iirc would have been a lot more with a few choice parts which i would have out on till i flogged it

 

any other thoughts on this for the nite pf

 

MarkyMark.

I remember the car you built. Was a sort of magenta coloured FRS rep that ended up getting rolled.
Stripped it for parts a few years back with Simhopper

 

lamborghini orange with a gold pearl, focus rs bodyshell from fords (took 3months to ship over from germany and a few dollar), yep sold it and the fella rolled it going over a hill too fast and fecked it. pretty gutting after putting that much work planning and money into it

 

My personal opinion if you wanted a turbo 170 would be to flog the ST engine and fit a Focus RS engine.....failing that, Powerwerks do a bolt on supercharger kit for the 170's AFAIK, I know Will@M Devs has got one that he's compound charging at the mo.

Swapping out the engine would probablybe the most cost effective and reliable way to have a turbo170 although you will lose the VCT which you may have to anyway!
