i was wondering if the series 5 turbo is just oil cooled, or is it water / oil cooled?

much appriceated.. thanks

all the turbos were water and oil cooled.


For s5 and s4.........

the water for the turbo is feed via the lim and the lower part of the wp housing.

the oil feed is at the top of the front iron by the cas and the return is on the front cover by the omp.

 

well, im putting a s5 turbo on my GSL-SE so im going to tap into the stock oil pressure sending unit for my oil feed, then tap the front cover for the oil return line, i have a modified TB with the cold start assist removed so i am going to use the coolant feed and return lines for those for the water cooling on the turbo, my question is, is the turbo water pressure drained or gravity? i assume its pressure drained and i already know that the oil drain is gravity drained....

thanks

pressure

due some porting on the wg also. I've ran both s4 and s5 ported and even the ported s5 is still lacking.

I'm not very familiar with the early 13b's. Do they have a return on the rear iron for the thermo wax and one on the wp and is that what your planning to use? That would be a neat way of doing it.

Is this a common swap for earlier gens?

EDIT :
I assume you don't mean the sub-zero starting system (aka cold start assist) but the thermo wax system.

 

yes i do mean the thermal wax pellet, not the sub zero injection tank

 

Gregs, the stock oil pressure sensor is located before the oil filter.. you dont want to feed your turbo with unfiltered oil, do you?

 

well i was planning on using AN lines, and summit sells those AN inline oil filters, so i could put that before the turbo. i dont really see it being a problem
