Relocating coolant hose below turbo
 

Is there a better way in relocating the coolant line without buying one? Im thinking of cutting that nipple and blocking it off there and then cutting a hole and welding the nipple their. See picture. Open to ideas

Do you mean for your lower rad hose, or the heater core line?

Im trying to get rid of that whole bracket so i got some more room to work with my manifold. Heater line will stay cause its been freakin cold. I am referring to the radiator hose.



BTW i forgot the die grinder at work :facepalm:

But i cleaned up my exhaust ports fine. See my other thread ;)

Ah, I was wondering why you would want to mess with your heater in this weather :). Are you going to be able to get the die grinder, or are we just tuning tomorrow? Oh, and the exhaust ports look nice btw.

Dremel FTMFW! I may start my manifold tomorrow. Got all the junk i need just need to move the rad hose

I'm in this same boat right now to finish up my build. I think i'm going to clip it 180*, cut off the heater hardline after the first bend and plug it in there, get it to stay somehow and run a hose between the cut pieces of hardline. I imagine i'll have just the right amount of hose leftover after I shorten my oil return line for the new turbo location.

in the same boat as well, i need more room. my hot side charge pipe is rubbin on the lower rad hose, its all up in my damn way. in for answers.......

damn just looking at this in the miata yesterday. was thinking about pulling it and having a flange made and fabbing it to hit a 90 maybe straight forward since my a/c is gone.
i wouldn't even think of modding the oem part. but damn that lower hose is a jacked up mess.

I definitely need my heat. Gonna go get a hole saw and ill post up the outcome. The only possibly concern is that since the flow is redirected that it will hinder my cooling efficiency. But, Ill try it see how it works.

Awesome. I'm committed now.


Thank you for the pictures slutz

Dammit! That was going to be my suggestion. Flip it, and run a flex hose to the lower radiator barb. I welded a small .25" plate over the heater core line, putting mine to the upper radiator line for track driving and no heat. I could drill and tap that plate for a heater line down there though.

You can do something like this.

flip the stock one around.

k....now after you flip it what do you do fo the heater core line?

This:

what neo did was cut the stock hardline, stuff it in the housing and hose clamp it in place to keep it sealed.

that whole piece is alumium right?

ill probly be doing this....i cant afford the BEGi fix for this!

this.

doesnt look AC friendly! but other than that, it looks like it gets the job done....

AC is over rated anyway.

Lol. Do people actually have a/c?;)

FUCK YEH!

georgia summers suck ass!

Looks great. Man I wish I could weld aluminum.

I'm going to be doing the neo way for sure.

you'll put the AC back in when you're over 25.

Lies

Western Washington isn't like the rest of the country. We have maybe 7 days a year where AC would be really nice to have but its pretty easy to do without. Most people dont have AC in their houses around here. In fact, i've never had AC anywhere i've lived in/around seattle. When the heat comes we tend to embrace it rather than hide from it.

And I know plenty of people without AC in their cars that are well over 25.

yeah i know, i rarely used it in CA as well.

I am well past that.

Are there currently any other options available off the shelf for this, or is Begi the only one that makes this? What do you guys that have an Absurdflow vband lowmount setup use for this?

EDIT:
I just came across the ARTech mod

Wouldn't a FWD inlet work in this situation...?

I just flipped mine around then for the heater core ran a rubber hose back to the place where it normally connects.

Doesn't the stock water pipe just slip into the mixing manifold? How did you connect the hose to that, did you hack up the water pipe?

Another thread resurrection, arise from the dead thread, you're needed again...

I have an MSM, with A/C and P/S, and a low-mount EFR6258 but unfortunately the lower radiator hose obstructs the barb where the EBC hose needs to connect to on the compressor's housing (the location is pointed to by the green arrow):
https://www.miataturbo.net/attachmen...ine=1383472882
The yellow "circle" shows where the water inlet barb was modified to provide some clearance for the EFR6258 but it's not enough to allow the EBC hose to be connected.

Here's 99mx5's setup which shows the EBC mounted and this hose connection (approximately 4 o'clock).
https://www.miataturbo.net/attachmen...d-109_1168-jpg

99mx5 modified his water inlet and re-routed his radiator hose forward, through the belts and pulleys:
https://www.miataturbo.net/attachmen...k-dcp_4903-jpg
This looks "scary-close" to the belts and pulleys and I have a larger sway bar which means I can't really take this route.

After spending a lot of time under the car and feeling around under there, I believe that if the water inlet's radiator hose barb is rotated to point somewhere between 45* down and straight down instead of parallel to the ground, there is actually enough room to run the hose behind the A/C compressor and under it, straight to the radiator inlet and give me clearance for the EBC hose. You can see in the top photo that there is enough room for the radiator hose to run behind the A/C compressor.

It may need to run at 45* behind the A/C compressor and the P/S hard lines moved a bit but it's a far more direct route than the convoluted across-and-weave OEM route.

Has anyone tried this before, it seems much simpler than other solutions so there must be some reason why more complex versions have been produced - and WHY didn't Mazda do this in the first place?

The part of the lower reroute has a metal part that crosses the AC belt. If the reroute ever touches the belt, the hose will not be cut by the belt.

If you're still looking for suggestions, here's what I did with my EFR setup with PS/AC and an ARTech manifold that was interfering with the lower rad hose to the mixing manifold. I have zero welding skills (except for the JB kind), so my solution was to cut off that angle altogether, create a new lip and hook up a flexible rad hose to the straight piece. This left enough wiggle room to route the flexible rad hose around the manifold.

It was only meant as a temporary solution to get me on the road (and to the track) quickly. I saw some of the ones that flipped the whole thing 180* and had the pipe coming out the front which seemed like better solutions, so I figured I would eventually have something like that. I'll look at it more this winter and decide for sure.

I just made my EFR setup with AC and PS, made a similar pump inlet mod as lokiel's and ended up making a heat shield plate that protects the water and PS hoses from the manifold heat.

Great work Harold.
I guess it is possible to relocate the power steering hose below the steering column if it is too close to the manifold?

Thanks for the updates guys.

Now I know why the lower radiator hose takes what I deemed to be a convoluted path rather than more directly behind+under the A/C compressor and straight to the radiator inlet, on LHD cars your steering shaft is in the way!

On our RHD cars in Australia it's on the other side so we have much more space there to route the hose as I suggested once the barb is modified. Mazda can simply use the same parts for LHD and RHD markets, it had nothing to do with optimising the hose routing.

Good Afternoon all,
Sorry to resurrect an old thread, but figured it would be better then starting a new one.

So I ended up doing the coolant hose relocation that some of the other guys did in this thread, but the problem I'm having now is just finding a custom hose that will fit. The guy I got to weld in the bung for me welded it angled a bit high which would not allow me to use a straight coolant hose without it kinking. I was thinking of using a piece of the metal coolant pipe that got deleted from doing this, and two pieces of hose instead of one to make the route work, but wanted some advice or suggestions from what others ended up doing, and I honestly do not know where I can find miscellaneous hosing to make this custom route work. Been asking auto parts store in my area, but they treat me like I'm dumb for asking, and can find anything online that supplies hosing I need.

Here are some pics of my situation. The coolant hose you see is actually the top radiator hose. It is actually pretty close to working, was thinking of cutting this, and using a piece of metal pipe to make this work.

I used TheBandit's billet water pump inlet and modified it a little to work with the turbo. Works great for me!

Don't ask the brick and mortar to find the solution for you, ask to see their hose wall and pick hoses that look like they might work.

done it many times with much success

Thanks for all the suggestions, and pics guys.
Made a trip to advanced auto today to look at all their hoses they have available, and found one that fit perfect with very little trimming. Called me a funny guy for looking through random hoses lol :P. How come it seems so many people that work at these part shops are never car people? Guess cause its just a job anyone can do.
Anyway, thanks again!
