2G Water line position

[Dsmdaniel18]

I’m installing a new 16g turbo but I’m wondering about the position of the water lines and how they go on the turbo I know the feed line comes from the block and the return goes to the water pipe I’m only wondering if the feed goes to the back of the turbo or the front?

Water pipe goes to front of turbo etc.

Okay so the feed line goes to the back?

It doesn't matter, I have a completely different factory coolant setup in my 98 auto. My water pipe is completely different

So I wouldn’t have a problem If I were to run them however?

I never really thought too much about it before, but as long as you have coolant running through the turbo you should be fine.

Who says you have to run coolant through a turbo?

Coolant is used to stabilize the temperature of the turbo, not to necessarily lower the temperature of it.

When you think about it, it's pretty redundant. The oil cooler is the lowest point on the engine and it directly feeds the turbo the coldest oil in the system. If it was important the oil cooler would also feed the coolant right to the turbo, but it doesn't.

Truly doesn't matter as long as one line connects to a cold source (water pipe, block) and the other connects to a hot source (upper rad hose area, thermostat housing) so water can continue to flow after the key is turned off. That's the entire reason coolant is in place...for people that aren't familiar with turbocharged vehicles and may turn the car off without allowing ample cooldown time.

I'm not deeply familiar with the center housing on MHI turbos, but some turbos have a siphoning feature to allow coolant to continue flow through the bearing housing after a hot shutdown to avoid oil coking. My advise would be to run the stock routing just in case MHI has a similar architecture.
