Ok, let me start by saying I am expecting to get flamed to no end for this post, but I've been on here for about three hours using that wonderful search feature and haven't found exactly what I'm looking for.

Basically I bought my car with a coolant reroute already having been performed. I also bought a used FM turbo kit and now I need to run the water lines, but can't figure out exactly how to hook them up.

Here's what I'm working with:







Please ignore just about everything else that's not water line related, a lot of stuff is not quite hooked up or just not there.

Now from what I can tell the upper hose has been rerouted to the rear of the engine along with the heater return line. The supply line from the lower hose is running to the block, heater, and to the sensor on the intake manifold.

Where should I try to hook in these water lines or am I looking at having to pretty much re-do the routing?

What I was considering was running a t-fitting from the supply line running to the intake manifold, but I hadn't figured out where to hook in for the return.

Again, I expect to be flamed, but I definitely tried to figure this out and I'm stuck.

 

Just tap into one of the lines going to that little heater block on your intake manifold. It doesn't matter which one. Cut one of the lines, feed it into a port on the turbo, and then the other port on the turbo connects to the other side of the cut line. Profit.

 

I wasn't sure what the hell that thing was to be honest. I had considered just tapping into those lines for feed and return, but I wanted to make sure I wasn't going to be messing anything up.

 

Just tap into one of the lines. Leave the other line unaltered.

 

I responded to your PM with a short description of what I did. Here is also a guide on what I did based on what Tom did originally. https://www.miataturbo.net/showthrea...gracer+reroute

 

or use that long bastard that comes out of your oil cooler (comes up between the IM and Head, and goes back down to the mixing manifold on the drivers side.

Take end off mixing manifold, attach to turbo in. Take turbo water out, run new line to mixing manifold.

 

1. cut that 3/8" line in half.
2. put one side A of cut line into the side A of turbo
3. put one side B of cut line into the side B of turbo
4. ?????
5. Profit

 

Bingo. Once I figured out what that thing on the side of the intake manifold was (FIAV) I had no worries about it getting post-turbo coolant.

So that solves that.

All that's left:

Oil return line
IAT sensor
figuring how the hell to hook up the IAC hose.
