Brain, where did you get that pipe?

BEGi.

 

$? How long is it?

It's not terribly long. Don't have one handy, but the unthreaded portion is less than an inch.

Here's the 1.6 sensor:



And the 1.8 NA sensor:




It's good enough for the stock config. Either way, you're measuring the water coming into the block. I agree that putting it in the back is better, but frankly I don't give a **** about the stock 1.6 fanswitch. Any seroius 1.6 user should already have the fans under ECU control, or have a switch under the radio. Or both, like I have. If BEGi decides that they have room to accommodate it on the spacer, then great. But if it's down to that or another NPT hole, I'd go for the NPT hole. Besides, Bell is going to have a hard time finding a plug to fill that unused metric hole, and the majority of users don't need it anyway.

You could always put it in a pipe section placed in series with the upper radiator hose.



On a flat plane, no question. I was worried about a tapered thread going into a convex surface. Still, that spacer does look pretty thick. You're probably right. Just make sure you don't bottom the tap while threading the hole, use some teflon tape and it'd probably be fine.


I've modified the drawing slightly, but basically this is exactly what I want. Including the pipe and the hoses to hook it up.

But without the drawing of a *****.

 

If the wall thickness is 3/8", then the minimum length of the threads will be 3/8", the rest more. So the radius of the pipe shouldn't be a concern. My numbers are from a machinist handbook BTW.

EDIT: BTW I do understand what you're saying about the surface being convex. But it's not enough to matter. Only takes 1 thread around the perimeter to seal the fitting.

 

I honestly don't remember what I paid for them I purchased them over 6 months ago.

it's 16.5" long.



My question is, where does one find a Kia water neck? I was going to use a allen-head cap to fill the hole, that's my broken thermoswitch in the picture.

 

95-97 kia sephia. Has a mazda BP 1.8 from the factory.

 

I know that. I was leaning towards, like, where exactly could one pick one up?

 

I'm thinking... a Kia dealer maybe?

Or eBay.

Or a junkyard.

Or you could wait for Rican Racer to buy a Sephia, and then steal his.

 

Junkyards. Kia gets bumped into and the insurance company totals the car out because they don't hold value for ****. So they're plentiful. Just have to look. I have 2 or 3 kia water necks, another from a protege, and another from a 1.6 miata. I'll be using 3 of them for my reroute. If they become popular I'll get a few next time I'm at the junk yard. The protege part is the same IIRC. They're all similar.

 

I think I'll be fine with my housing...we'll see.

 

Got mine from the local U pull it. They usually have quite a few dead Sephias.

If I have time this weekend I'll go and grab all that I can find for you guys. Just pay me what it cost to get it and ship it. No promises though.

I'm in, we don't have junkyards like you guys do, our **** is all old and gay...

Pick me one up and I'll paypal u asap man

I can go look at our local junk heap too. I have two local yards that let me walk around and have quite a few cars.

Scott, if you can't find a Kia neck get the machine shop that fixed your head to cut that nipple off and weld it up.

 

I just realized the begi spacer with the pipe can just be flipped around to point to the exhaust side and still bolt up.

So all it needs is a bung for the coolant sensor and ur done.

 

Did you use an allen-head plug? The tip of the bung sticks out exactly 1" further than the CAS.

 

When sourcing the neck from the sephia are we also looking for the front one?

 

I have a 1.6L piece on the way to me right now, but would much rather deal with the Kia piece. So if anyone finds one at their local yard, I'd like one.
But if I get a chance, I'll run up to the local pull-a-part and see if they have any too.

 

The O.D. of that pipe is way too large to fit a heater hose onto. It's designed to accomodate a radiator-sized hose.

The welded pipe needs to go away. Just turn the spacer on a lathe to accommodate a thermostat on the firewall-side, drill a few holes in the spacer, tap them, and screw in the appropriate fittings and sensor. No welding, no fuss, no muss.



Steph, I have a question for you. In the second-to-last picture that Braineack posted in that long series of his, there's a pipe that runs front to back to carry coolant from the rear outlet to the radiator inlet. The pipe is of a uniform diameter, and smooth.

On your website, there are several pictures depicting a similar pipe, however it has mounting tabs to secure it to the intake manifold and is of a slightly smaller diameter along most of its length, with welded adapters on the end to mate with the radiator hose. I've attached pictures:







I like this design a lot. The pictures appear to be from a 1.8 engine, have you done this for the 1.6 as well?
