I have a dsm T25 with both water and oil cooled. Was just thinking, what if instead of running coolant straight from motor to turbo back to motor... how about having it run thru the radiator first before going into the turbo, then back to motor? Reason being, my bro's hb has an automatic radiator with the two nipples at the bottom of the radiator for an automatic tranny which is not being used because the d16z6 is running a manual tranny.

On another note, with that being said- I could probably run oil thru that if I wanted to can't I, especially since thats a totally seperate section from the coolant above (meaning it is not connected)... or am I wrong?

Any ideas, questions or suggestions? Anyone ever done this? Cool beans!

 

your almost definitely going to have an oil leak if you try and use the coolant ports for oil. Not to mention, coolant has better cooling properties, oil has better protection for contacting surfaces. The slightly lower temps of the coolant really arent going to do much for the turbo but your free to do so if its a more convenient setup. The oil and coolant together do the job just fine if you have good pressure. Hope that helps

 

Yeah oil really doesn't work well as a coolant. If you run water through the turbo it will probably help against oil coking and you won't have to turbo time you ---- as long, but they are used turbos we're using so they do have a degree of coking on the to begin with. I'd run them if it's not too much hassle. It can't hurt any.
