can any one tell me the pros and cons for theses t3. which ones better ect.cheeRS

 

They are both the same in that they are oil cooled, but the S2 has water cooling also, neither is better and there are no performance differences!
The benefit of water cooling is that the turbo will not suffer (as much) with heat soak when shutting the engine off after a hard run, and so is less likely to cook the oil that left sitting in it.
A lot of us disconnect the water cooling from our turbos to keep running temps down (including me) specially as Ford decided to reduce the size of the radiator on the S2! But you MUST let the car idle for a least a minute or two before shut down or you will cook the oil and reduce th life of your turbo.

 

My water lines are still connected up to the turbo, does that mean I'm able to get away with turning the car off and not letting it idle? (I always let it run for a minute or two to avoid heatsoak, just wondering)

 

I converted my series 1 to water cooled and still always let it tick over for 30 seconds or so.

 

IMO Always worth doing whether your water cooled or not!

 

the cores on a s1 non watercooled is different compaired to a s2 watercooled, i would not suggest you take the water pipes off the turbo, it hardly keeps its cooler plus garrett/ford designed it to be water cooled, dont see why they would spend time/money on desiging a water cooled turbo to not be watercooled ??

 

I think it was mostly due to Ford knowing that most of the owners of Series 2's would turn the car on, rag it 10 miles to work/down the shops then switch the car straight off without any concern for the turbo.

If doing track days I would disconnect it.

 

cheers guys! i only asked coz iv got a s1 rad and turbo was going to put it on the bonus. my s2 would allways get hot in traffic and then die. would it still be worth doing or shall i just put s2 rad and turbo. cheeRS

 

IMO it make no difference mate, so long as you let it ldle for a bit before you turn it off, I'd fit which ever one is easiest, or in better condition.

 

cool cheers bud.well rad is in good nick. its been stored for 15 years and the turbo ok! so i will just see how it goes.

 

ofcourse it makes a difference, the turbo is designed to have water circuling it at all times, all the idle is going to do it let the oil(which is lubricating,,,not cooling F all) cool down very slightly,,

i would never run a s2 turbo without the waterpipes, sure it proberly will work fine but hey its there for a reason,

 

personally i would never disconnect the pipes from a water cooled turbo! i paid over £600 for my turbo and it was designed to be water cooled so thats how it will stay!
I bet if you rang a reputable turbo company they would not advise it either and would void the warrenty if you did it!

 

His question was whether or not to fit the S1 turbo and Rad or get a S2 turbo and Rad!!!
Hence I said it doesnt make a difference as either setup will be fine

But....... IMO and a lot of others, running without water cooling is 100% fine! Ford did do it for a reason, and that reason as said above was so that Joe Public can just pull up and turn there shiiny new RS Turbo off without the risk of shortening the life of the turbo

It's a debate that has been had many, many times on here so for anyone thats interested just do a search, some will say 'yes' some will say 'no' each to their own.

 

the thing with watercooled turbos is they heat the water up quiker in winter ,so your heater will work quicker and help clear window's ,that's it ,i alway's disconnect my water pipes if i'am running more boost as if you see a turbo on full boost at 20psi the exhaust housing is almost see through i don't think anyamount of water is going to cool that down
it's only the oil that will cool the shaft down down and take heat out of it as this is the only thing that will past around the shaft .

 

i've a s1 oil cooled turbo in my s2. i'm using an apexi turbo timer. No problems at all

 

I have tempeature problems in trackday too, 3 laps and needle is near red.
Is there _fact_ how much cooler engine would be if i disconnect water "cooling" from turbo? I am not driving winter at all, and i have patience to tick it over 30 secs after harder driving.

edit: Std T03 turbo.

 

the water cooling does what it says, helps to cool the turbo, i wouldn't reccomend running a roller bearing turbo without a water feed but its not so bad on a conventional turbo, as said, just treat it with respect as you should do water cooled or not!
A fiesta with a T3 is a classic case, most have a S2 T3 with water cooling, i always reccomend leaving the water disconnected as otherwise it tends to make the car run to hot...
As for letting the car idle when finishing a journey, i normally do the last mile or so trying to heep the car off boost, then when stopped idle for 30 secs to a minute, if its been driven hard then raise the bonnet & let it idle for 5 minuted!

 

s1 turbo and rad is then cheers for you help.

 

i went all out making my fiesta run cooler as it used to get stupidly hot even just sitting at traffic lights for a minute.

in the end ive run the T3 with no water cooling, put a wider xr2i radiator on, put a water swirl pot on, and twin slim line fans on a switch.

it now runs sweet and doest get silly hot.

 

I do the same as guzzler, drive the last mile of my journey off boost then let it idle for a min or 2 before switching it off

 

Yup me too!
