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.
