Just wondering what the pros/cons are of each, if anyone feels like educating me

 

They are all "oil cooled" , some also have water cooling for a little more protection.

 

Water cooling is nice because you don't really need to idle your car before shutdown and continually cools the turbo. But setting up a turbo to be water cooled on a N/A engine might lead to probs with the coolant system since its not meant to take on the extra load of cooling a turbo. I personally never bothered water cooling mine and just idle for a bit before shutdown.

 

Dnt stress about HAVING 2 water cool it ..
Just let it idle a little bit b4 u turn the car off.
Ull be fine

 

i never idle it... jus turn the bitch off the turbo cost almost nothing and its so small... i call it garbage.... if someone can help me find a t3/t4 u can have my turbo jus for finding me a CHEAP good good priced one... im talkin below 300 cuz i can get one for that much

 

water cooled bearing sections have almost twice the life expectancy of the ones that are just oil cooled. you can also run higher oil temps with a water cooled one, i say if you have a choice, take the water and oil cooled bearing.

 

My turbo is watercooledand I use it(14b). I have seen next to no increase with it. I have a stock alimunum rad from a 91 Auto civic.

There is a slight difference but when you up the horsepower on an engine that creates more heat also, so someof it is from that too!

 

When I do my kit im only running coolant to the turbo. coolant cools better than oil anyways.

 

if you do that your turbo wil wear out in the first few runs. are you joking though? it needs oil to lubricate the bushings in the center section and to cool it down.

 

There is no argument for running only one and not the other that makes sense.

Just run everything that you have at your disposal. If you can run both then bomus. Why not do it.
