Rb25det Turbo Water Cooling Line Routing?

[Chris Wilson]

I have rebuilt an RB25DET engine that had a none water cooled core Apexi single turbo on it. I have now switched to a Garrett water cooled core unit and need to plumb in the coolant lines. I know one goes to a tapping towards the rear of the block on the exhaust side, the other seems to go around the back of the block and plumb in on the intake side somewhere. Can anyone specifically tell, or preferably SHOW me where the stock water cooling line plumbs in on the intake side please? Thanks.

its located on at the back of the intake plenum where the 6th runner is, its at the end of the water channel that runs along the injectors it should have a little brass hose connection coming out the back of it toward the gearbox, it can be difficult to get to, if you have trouble finding it ill take a photo but its really easy to find..

OK, found it, it was capped off, thanks for taking the time to help me out, cheers Jarrod

no problems, also i forgot to mention that the connection from the block on the exhaust side is the turbos inlet that enters at a lower angle than the turbos outlet that connects to the back of the runners on the plenum, its meant to help keep the turbo cooler and stops the oil from coking up after you turn the car off.. i actually had them around the wrong way for a while the angle should be about 15 degrees from level
