Special K Posted September 6, 2022 Report Share Posted September 6, 2022 Am I the only one that thinks is a little ridiculous? Points if you buy a well engineered kit, sure to do the job and increase reliability. Free if you concoct some sort of breakfast machine type thing out of "existing parts." Now, maybe it's just my small monkey brain, but what's the point of nickel and dimimg points, then providing a work around to accomplish the EXACT SAME objective? Why not just make the thing free or assign points instead of trying to do both? Or is opening this can of worms going to give everyone flashbacks to The Great Window Net Debate that wasn't even enforced at Road Atlanta this year........

There is another item on the list that is a different price for "homemade" vs "bought" and it really doesn't make sense. Put in a petition and it will get reviewed again - Maybe or Maybe not change the answer but it would put it on the list. 3 Quote Link to comment Share on other sites More sharing options...
obscene Posted September 7, 2022 Report Share Posted September 7, 2022 Is this a similar situation to how aluminum radiators used to be points? It was reviewed and recently changed to no points. 1 Quote Link to comment Share on other sites More sharing options...

A reroute just pushes the water out of the back of the head, then to the radiator rather than in the front and back out the front. Miatas have a problem overheating the number 4 cylinder so a reroute is a step in the direction of saving your engine. It's nothing more than a hose, a block off plate and a junction in the back of the head to direct the water through said hose that returns to the radiator.

This sounds a lot like the e30 cooling setup. Normally there is a hose off the rear of the block which goes to the heater core and then returns to the thermostat / radiator. Some teams block it off when removing the heater core, some add a 90* fitting and route a hose straight back to the thermostat housing (this is what I did). I would definitely call this 4.7.2. Items that are point free: ... • Cooling system hoses and vacuum lines ... Add that hose and the fitting (it doesn't already have a usable fitting there??) for 0 points. 1 Quote Link to comment Share on other sites More sharing options...

You thought right. The doohicky on the back of the head has the thermostat in it. We have the supermiata kit. We'll worth the stupid 5 points I take over the 0 point option of a garden hose, a collection of rusted hose clamps scavenged from the broken office chair that won't stay up and a block off plate made from a poorly cut piece of diamond plate from my cousins OBS F350 he met his 3rd wife in while on vacation in Scottsdale........ 1 Quote Link to comment Share on other sites More sharing options...

55mini Posted September 8, 2022 Report Share Posted September 8, 2022 On a Miata this is a very simple process and even moving the stat to the back. You make a small blanking plate for the front and cover the old stat position. I even tapped the plate for temp sensor which gave a better temp reading and then got hose for added lengths.......so technically 0 points since I had a blanket amount of aluminum in my points count already. 2 Quote Link to comment Share on other sites More sharing options...
ETR Posted November 25, 2022 Report Share Posted November 25, 2022 Bringing this back, because, well, we'll be 505pts in 2023 for this. A few thoughts- We've been claiming 5pts for the kit based on the tech desk article. Tech desk article is 2, soon to be 3 years old. I see the update earlier this year about what constitutes DIY. How long is a tech desk article valid for? Forever? <- @Bill Strong Can't find cooling reroutes or similar terminology in the BCCR, or where the BCCR adds weight to the tech desk articles. Radiators became 0pts since the article and cooling system hoses are 0pts. I'm not in the "make everything free" camp but I'd like to not claim 5pts just in case anymore.

turbogrill Posted November 26, 2022 Report Share Posted November 26, 2022 Isn't the answer to this obvious? 4.7.2 says coolant hoses are free. BCCR would have to take precedence over tech desk? (I am not sure all old tech desk tickets are reviewed each year due to changes to BCCR) Quote Link to comment Share on other sites More sharing options...

Then what do you do with the sensors? Like the 1.6 with the temp / fan sensor in the front housing and the temp sensor in the back housing. You'd have to extend the harness I assume since you can't plug them into the opposite plug because they're different, right? The NB 1.8 only has a rear temp sensor, so do you weld a bung onto the cast pot metal / chinesium front housing when you move it to the back? These issues are why we bought a reroute. Same outcome, but easy and safe (for us). Some of you smarter miata whisperers may be able to pillow talk it into not breaking your heart better than us though so I really am interested in how this works.

There's a plug in the back you can pull out and the temp sensor fits in there. It's on the passenger side of the outlet. If you reuse the rear cover the temp sensor fits in there for the front. I did not use it that way since I signal my fan from my ECU now. If you really want to sweet talk your miata you should pull all the unneeded wiring out of the factory harness. I got like 17lbs out of mine. Edited November 28, 2022 by WastedAccounts missing letters/typos additional comments pictures Quote Link to comment Share on other sites More sharing options...

I've glossed over that plug so many times I forgot it even existed. So then I assume you're capping off the front housing, yes? If so, where is the thermostat going?
