I'm not saying this is ideal, but it should be roughly "as ideal" as our stock oilcooled setup, shouldn't it? I agree, if you're going to get it done, you may as well get it done "right". But, apples to apples...

(which would become unsalable at that point).

Yes,
no need to modify because K-24's are made for our header/exhuast set-up
(but remember the K-24 for a 993TT is different than the K-24 for a 996TT)
Make sure you know what you are buying!

What about with a K24/26 style turbine outlet? Would this negate the need to modify the exhaust flange?

Because yes, the GT ball bearing turbos DO need the water cooling unless you want the 1200+ degree turbine wheel to transfer the heat through the shaft into the bearing and essentially fry the bearing almost instantly on a GT35R (the larger the turbine, the quicker the bearing with fry)
GT25's have gotten away without the water cooling because the wheel is rather small and does not transfer the amount of heat a GT28/30/35 would
the only large BB GT turbos that do not need the water cooling are the GT47R and GT55R which use a different bearing set up and have heat extractors build right into the CHRA

(GT2860RS) with .64 A/R'swe do not offer the ECU tuning, GIAG, Evo and protomotive are options

The purpose of watercooling is not to keep the CHRA cool when running. It's to keep the oil from coking when shut off. This is why the hose runs uphill to turbo and uphill away. The boiling causes a thermal siphon to pull the water through until the temperature cools to the point water no longer boils.
Again, I agree watercooling is ideal. Will not connecting it cause things to fry instantly? I haven't seen this to be the case.

I have the disco potatoes (gt700) Tial turbos and lets just say 24lbs of boost and race gas, these turbos launch you. You get full boost by 4400rpms makes these turbos absolutely lagless. an easy 650whp+. Tialsport- you guys figure anythign out with the gt32 turbos with k24 hot sides. thanks
