GT28R coolant line routing
As it is right now I have my coolant lines routed inline with the IACV. This works but I find it heats up my IACV and throttlebody very quickly and causes idle problems(lumpy) and high water temps.
I was looking at some old posts and some people are routing things differently than I have, For example some use the freeze plug on the front of the block for a feed and then return it to the rad. This sounds like a great set up except for this.
Wouldnt the coolant flow circulation be at a standstill since the thermostat controlls water flow from the rad to the block? Coolant flows from whatever port you decide (lets say freeze plug on block) to turbo then to rad. Now the coolant will only "flow" when the thermostat is open thus only cooling your turbo every so often. Isn't the idea to have the coolant flow constantly?
Thanks

On my OBDI gsr I ditched the factory oil cooler and used one of the leftover ports for coolant and then taped my radiator for a return.

as I said in another thread where you posted that, I highly recommend against tapping the radiator. That would also require you to remove the thermostat.
just use the lines like you were thinking to bypass the throttle body. I've used those before and it's worked perfectly fine on a GT28R.
that's a zippy and responsive little turbo. You should like it for low power levels (200-230whp)

because below a certain water temp, the thermostat is closed, meaning the water is only circulating through the motor, not through the radiator as well. So you're essentially robbing water from the motor and dumping it to sit in the radiator!
