sooooooo


anyone with GT series turbo running in their car with the coolant lines plugged up? ive been running the coolant lines and ive been told by a few people to plug it up so it doesnt heat up the coolant so much. Basically only use the oil lines. anyone do this or have insight about this? thanks!

 

Any reason in particular why you would want to not run a coolant line thru the turbo? Is the car overheating or running abnormally hotter? I'm planning on running a coolant line to my GT35R, I don't see why you shouldn't run it, its there for a reason. I was also told that it isn't neccesary to run a coolant line but I rather be safe than sorry. I think running the coolant and oil to the turbo would help preserve the turbo longer but I'm just curious to know how much hotter the coolant gets from being in the turbo and if that does have any affect on cooling the engine itself.

 

my previous 2 turbo setups didnt have coolant lines running to them. The car ran alot hotter once i started running coolant into the turbo. On 85-90 degree days the car will begin to overheat if i have to sit in traffic for a bit. I believe they are there for a reason too but ive been told and ahve seen others using no coolant to the turbo on a GT series turbo.

 

You can also add a smaller cooler separately to cool the coolant like the Air to water setup. The downfall is youll need a small pump to pump the water back into the turbo. Just thought I throw that out there. You guys change that coolant out often?

I would run coolant lines on those expensive BB turbos. It will extend the life of the turbo.

 

You HAVE to run coolant lines if it's a ball bearing turbo and you want your turbo to last. There is no two ways about it. Unless you don't mind replacing your turbo couple months.

If it's a non ball bearing GT I don't know if it's wise to not run them or not. Maybe consider some cooling mods for either the oil or the water or both to try to pull more heat off. Also an oil temp gauge and water to keep a more detailed eye on the temps, then you can change the setup around and know exactly what the results of that change are.

 

As Neal said, BB turbos *MUST* run coolant lines, since BB turbo center sections use a very small volume of oil compared to a non-BB floating center section turbo that also uses the oil for coolant.

Are you sure you bled the cooling system enough to eliminate all the air?

If so, maybe your cooling system is just that close to overheating. I'd look into a Koyo or Griffin rad and a good set of fans to buy you some protection/headroom.

 

make sure your fans are working, thermostat is not stuck. I wouldn't think the turbo would heat up the coolant that much.

 

Neal and Ice,are your sure all BB turbo have coolant going into it?Cause I'm pretty sure,I don't have coolant line on my Turbonatic BB turbo from my PFI kit,or can I add the coolant line to the turbo,if it doesn't come from the factory?

 

T04B is an old **** turbo design and the design was different back then, but any modern ball bearing turbo requires water cooling.

 

I would highly recommend you run a coolant line to that turbo. That T04E from Turbonetics is one sensitive turbo that will need water cooling. I promise you it wont be long before the seals go out on it due to heat. Run the lines at your earliest convenience!

 

just use the line that goes to your throttlebody. Just make it longer.

 

OK,I know I can split the coolent from the TB,but where do I connect it to the TURBO?There's no connecter or predrill holes that I see of.

 

Turbonetics turbos are single ballbearing turbos(compressor side) NOT dual ballbearing turbos, therefore they still use a floating sleeve type bearing which means they use an additional volume of oil for cooling like older T-series type turbos.

Basically, the manufacturer designs the center section cooling passages to flow plenty of oil(sleeve type) for cooling or just enough oil for lubrication along with external passages for coolant.

In short, you can't add coolant lines to a turbo not designed for them, so if it has coolant in/out ports, USE them, otherwise don't worry about it.

 

Thanx ICE.

 

one prob i have is my turbo sits less then 1 inch from my radiator. Im sure it adds alot of heat to the coolant.

 

Maybe put a thermal blanket on the hot side of the turbo. Jet hott, or ceramic coating. Something.

 

wrap that bish run the coolant lines, you have an expensive turbo my friend

get a Griffin radiator, it miiiight clear your setup and end your overheating woes and then you can come down to SoCal again and not overheat up the grapevine

 

already have...

 

got a link to the Griffin radiator? thats not the one that is almost double the thickness of the stock one is it? for sure that wont clear....

 

when I get mine bring your car down it looks like it hugs the core support alot closer and might have enough room for you to clear juuust maybe, Andy has his in and it still seems to have decent clearance

 

Well, I have run a GT35R for a year. I took it off recently to try a GT40R. I did not run coolant lines and it runs every bit as good as it ran when I first bought it. My recommendation is still to plumb the lines and deal with the overheating problem with a bigger/more efficient radiator. The lines were put there for a reason!

 

change the turbo pipe..

 

And what do you recommend he change to?

 

sell your kits.
