Im trying to connect all the coolant lines to my turbo, (Evo3 16g) on my 6 bolt swap but the previous owner must have bent the lines because I have searched for two days for a clear picture of where they go and everyone i find seems to look different.

I know one is a return and one is a feed. On my water pipe behind the manifold there is a downward facing brass fitting right below the oil feed to the turbo from the head, would this be the feed? and would the return be above or below the thermostat? Thanks

Here is a picture The water pipe fitting is hidden behind the turbo outlet. Also where does the vacuum for the actuator come from?

The banjo bolt on the front of the turbo (coolant feed) is connected to steel tube in the shape of the letter U and bolts to the water pipe behind the turbo. if there is not a spot for it to bolt up on the water pump pipe then its a n/t h2o pipe, replace with turbo h2o pipe. Now the other coolant line is the one on the rear of the turbo, that feeds to that barb fitting just underneath the t stat. the turbo actuator is going to a pressure source, any pipe after the turbo or the P on TB. If you wanna get fancy, get a MBC. That oil feed off the head is a nono, run it properly off the oil pump housing, especially if you want your turbo to last.
 
Boost source to actuator; boost controller in between if you have one. Cap the nipple on the intake if you're no longer using the factory boost control solenoid.

Rear coolant line of the turbo to the thermostat housing, front coolant line to the fitting on the block just behind the turbo.

May want to let Mitsubishi know that every TD05H turbo they ever installed on DSM's and Evo's is improperly-fed.

Is there a specific or "best" way to route the SS line from the head to turbo? In the above photo, his SS line is much longer than needed and is sagging down... Just curious if there are specific things to do other than the obvious of not having any kinks or pinches etc to allow oil to flow with as little resistance as possible ie. straight line....

thanks.

I've used this kit. The line is super short works perfectly
