putting the s14 waterneck on my s13 motor and need to make a new water return line, what size thread is the fittin in the water neck so I can order the adpter. ad are the taka/circuit sports stainless coolant lines are normally -8AN lines/fittings? The lines I have now are the ones that came with my apexi turbo but just have a nipple to the back of the block hose.

This swap comes up so often, and this is an important part of it obviously, but no one has covered it in a while.

Here's the FSM snippet, so everyone knows what you're talking about. Anyway, it shows the same banjo bolts as the rest of the water fittings. M12x1.25, or M12x1.50? Forgot the pitch.

Edit: about the lines, I believe most turbo line kits are -8 AN lines. Fittings depend on what they're going into, obviously. If you're ordering lines, just tell them you have the S14 water neck, and they'll include the correct fitting (instead of the hose clamp fitting for running around the back of the motor).
