My Magnefine filter is of course on the inlet line to the turbo with a few brass adapters same as the turbo saver and Red's setup does, filtered oil only to the turbo.
With the turbo saver you should be good to go with filtered oil always going to the turbo, that's the way it was designed. I don't like the leaky hoses some have with that system or relocating the oil filter which I think that system does, plus I have and like the RJC biggie oil filter setup already installed for my motors.
I don't think the turbo increases the water temp.s. much as I'm running 20 year old half plugged stock rads. here, in both my cars, and I do hit 210 tops in the summer with the A/C on in 100 degree weather, but that's rare, both rads. do need a good 3 row recore, I didn't really notice an increase in water temps. with the turbo install.
Never a problem in weather up to 90 degrees that's for sure.
I don't think I would want to add a water system to do it, plenty of flow and volume is available in the stock system even if the temp.s. are hot in the turbo the water should stay relatively cool with decent flow even in that local area, and no I haven't measured any of that, the bearing water cavity is a small area hence my desire for good flow using the heater hose send and receive rather than the throttle body lines, water doesn't sit in there too long that's for sure.
The water cooling was rather easy for me to do with off the shelf stuff excepting the right angle fitting to point the front hose barb upwards.
That barely cleared the turbo when rotated for the install, had to mill a couple of corners off a brass block squarish type fitting to get it to spin freely and not hit the turbo housing.
I don't weld so Williams idea is out for me, brazing might work but I'd want 3/8" lines and barbs installed, for a true fabricator that's another way to go for sure.
Just getting that stuff out of the car and fabbed up would take longer than the T's and modifying the stock water valve location, it really was easier that installing the turbo itself time wise and work wise.
That GT70 turbo had 10mm bolts for the drain tube, took a couple of hours to figure out the only solution was to drill out the braided drain line and gasket match it, and hope the gasket would seal, it did with 10mm nuts and studs in place.
Months later I found 8mm to 10mm studs that might have worked for that, they aren't easy to locate.
Then there was interference with the studs and nuts with the Postons headers at the turbo inlet not being able to get a wrench on the large nuts to spin them, had to modify one of the nuts to work etc.
Plumbing is easy especially with that teflon goop and good hose clamps, and NAPA nearby
