Hallo,

i have to buy a new turbo and i'am very interested in a T3/T04E but the one full-race offers is only oil cooled...

and because its my daily driver and i have no oil cooler at the moment i'am a bit afraid how long this thing will live?

how drives a oil only cooled turbo? can i buy one or should i look for a water/oil cooled instead?

Thanks
Malte.

3/4 of the boosted hondas on here run oil cooled turbos only.

Turbos are lubricated by oil. The oil does help to carry heat out of the center section but cooling is not its primary purpose. You will be fine without a water cooled center section IMHO.

There are definate advantages to having a water jacket but I wouldn't worry about it if the turbo doesn't have one...

I would use a turbo timer though to help prevent coking.

Yes, thats true, maybe i didn't choose the right words ;-)
but isn't it so that without a water cooling the oil gets more heat from the turbo?
and how does the turbo can handle the heat generation without any water cooling? i think air cooling isn't that much hm?! or am i wrong?

so just three last simple questions:

1.) do i need an oil cooler with a stock oil system of a B16a1
2.) whats about the oil change interval's? is it theorecitaly possible to hold the stock interval? or should i better change oil lets say every 7000km?
3.) is just to install a turbo timer (i have allready one) the only thing that i need to guarantee a long turbo live?

if thats all... then i think i will buy one...

by the way... if i get ony... i can see a glowing turbo ;-) maybe thats a nice effect ;-)

Thanks
Malte.

The water jacket mostly helps with coking of oil. This can be prevented by turbo timing it every time.

1) No you don't need an oil cooler but it is always a good idea especially if you plan on long boosting sessions or track days.

2) I change my oil every 3000(~4800km) miles, sooner if I am autocrossing or beating on it a lot. The stock interval should be 3k miles anyways, much longer and the filter has lost its filtering capacity and the oil is loaded with contaminates. Regardelss of what Honda tells you, the oil should be changed every 3k miles.

3) Nothing can guarantee a long turbo life, however turbo timing it will definately help. Use a proper weight oil and maybe even a synthetic if you can swing it.

Honestly water cooling is a fairly recent thing. Many many many people have used a standard non-water cooled center section for just about any application and with proper care get a great life span out of it.

Thanks very much... i think i will buy that thing

i have a small little oil cooler..like 4x6 inches or so. maybe a little bigger

i dont understand why people dont put oil cooler, it keeps oil temps down even for street use. honda engines will run hot with turbo. put one one

i forgot where i saw it it was in a magazine (sport compact i think it has a 240 in the cover it was primer i think ) well they test it made the turbo spool a little bit faster than with out an oil cooler they tested it on a sr20. Has any one read this, other than i?

You must be talking about the S13 coupe project in Sport Compact Magazine. They made it hit 12's. hehe...for all the SR20 junkies.
Running an oil cooler will help the engine and turbo. I usually run an oil cooler from a junkyard....in between the oil from the engine and the oil to the turbo...

I've ran most of my turbo setups oil cooled only. You really only need the coolant if you're planning to really push the turbo. I say like above 7-10psi...use the water cool if your turbo has that option...won't hurt using it.

drift2004

yes that one

This guy ran a Mitsu 18G non water cooled turbo:

Only lasted 16000km with just 7 track days .

If you're going to track your car, I'd say get a water cooled turbo. I would've gotten it anyway. Better safe than sorry.

i plan on making 400-450 WHP on a B16, i don't think this is possible without a huge amount of boost and i also plan to push the car... why else should i make such a power when i can't use it

maybe sometimes on the track also but not so often i guess...

but where is the difference?! when i let the turbo cool down and install an oil cooler i think it must handle that without any problems...

Thanks

If you can find a turbo with a water cooled center section, deff get it. Even if it is a lil more expensive, it is worth it if it will prolong the life of your turbo. I made sure my new turbo was water cooled.

Does anyone know if Precision Turbos (i.e. SC-3427E) are water cooled?

i think it very hard to figure out which turbo is water cooled and which not. the only way is to write emails to the companies...

is there ANY other T3/T04E size turbo (which is good for around 400-450 WHP) that is water cooled???

Malte.

I have the SC34. and it's only oiled, not watered

Why bother? The turbo uses less than half a gallon per minute, why not use the oil cooler where it will do some good? A sendwich plate or spin-on adaptor is the only way to do this right, otherwise it is waste of time and plumbing. FWIW I ran 18 lbs on a Greddy 18G which is just oil lubed and it ran just fine, no bearing issues at all. Running more than 10 lbs on a turbo isn't 'pushing it hard' unless you are way outside the efficiency range of the compressor.

My turbo is cooled with engine coolant.
