stage 3 muppet

hi there i have a 2wd cosworth and have been given a brand new t4 turbo by a good friend ,after he abandoned his own project but ive noticed that the t4 has no water cooling on it ,ie no in and out pipes so is therefore air cooled only just wondering is it possible to run this setup on my saffy
which would mean i would have to bin the standard return to the header tank(one that crosses cam cover). and then the inlet to turbo feed from by thermostat housing im assuming would be returned to the header tank. is this right and has anyone done this before . and if so was it ok or do you think i would need a water cooled type t4 only asking as i know that the rs500 t4,s were water cooled
not bothered if i kill the turbo as it was a freebie but dont really want to do any damage to motor
any advice appreciated cheeRS

wont be a "proper" T4 mate.

It will probably be shit on your car and more hassle than its ever going to be worth...

why would it be shiiite then ? only askin as i had two s1 rs turbo,s and one was watercooled and the other one wasnt .still felt similar though
surely even if it isnt proper it will be better than my tired t3

I've just purchased a Turbonetics T72 and thats not water cooled either, i've been told it's fine to run them without water cooling.

what a load of bollox of course you can run it un water cooled we de water cool everything over 400bhp anyway and to say its not a real one without knowing is silly as alot of the race spec t4s never had water cooling

Have you fitted it yet ? / How is it ?

Got any pics

havent had chance yet as i need a drop bracket for the alternator and to make up a new actuator bracket as it didnt have one .
will post pics of the turbo later though also let you guys know what its like

am i right in thinking that the water inlet to the turbo feed will be returned to the header tank when fitting new turbo(as its air cooled turbo)
assume it will be safe to run this setup as far as i can see it will only kill the turbo at worse
who cares was a freebie anyway cant envisage any probs as have had a few motors in the past that were non water cooled turbo,s and had no probs

It will be fine you just have to make sure you let the car cool down properly before you switch it off. Mike R doesnt have his wter cooling connected and that runs anti lag and hes never had a problem. I am not running water cooling on mine either.

You run a pipe straight from the Thermostat side to the header tank if not using water cooling.

I would just make sure its not a cheap Ebay T4 as tbh they are fucking crap.

this is the point i was making but was told i was wrong

Well what experience do you have with a T4 to back up your claims Euan

The point euan is trying to make is that you get what you pay for.
Personally I would not go near these ebay specials with someone lse's barge pole let a lone my own.
They cannot possibly make and warrant a turbo of any decent quality for the price.
The point about water cooling is, it is NOT needed up to a point, as the oil does as much cooling as the water and is VASTLY more important, ie don't use castrol or mobil, unless you like buying new turbo's.
The fact that touring cars etc never used it is just a stupid statement and has no bearing on a road car, as it does not get a complete, no expense spared overhaul after every use.
Items made/adapted for road use can in a lot of ways be a LOT HARDER on components that race use ones, as the conditions vary so much, ie race brakes(F1) good on track, don't and never will work on the road.
Water cooling on the turbo's was undoubtedly put there for the longeveity of the charger nothing else, to stabilise as far as possible the oil temperature, to ensure no (little as poss) carbonising takes place in the oil ways leading to failure.

the water jacket (cooling) was used mainly to use the heat of the turbo to get the water temps up to operating temperature much quicker, can run the turbo perfectly fine without the (cooling) plumbed in.
