I want the parts.
Timing does suck as I can't justify spending close to $250 right now. When do you need to have payment? Could you take a deposit, maybe?

I think you should start a group buy thread of some sorts.


edit: also, why are you using ORB fittings? Are they cheaper to machine? I was under impression that ORB fittings cost more?

ORB - probably because o-rings are awesome.

Ha! I was just thinking of doing something like this myself, as my recently-purchased CNC machine will be here later this month. (Heh, a CNC all to myself, this is going to get crazy).

I would be interested in this "group buy", probably for all 3 parts. Keep me updated.

^^^ That. No chingering up NPT threads after multiple installations and removals. Simple O-ring replacement if it leaks, tighten until snug, because threads aren't doing the sealing. Soviet is right, timing on this is bad. I want one of the water pump inlets, but Christmas.

Why did you decide to go back to NPT for the thermo cover, though?

Why ORB ports? O-rings provide a more reliable seal than tapered threads with sealant, but that's not really an issue for a low pressure application like this one. I'm using them because there's a larger selection as far as fittings from ORB to AN.

I went to an NPT port on the thermostat cover after talking to CSR Performance Products and finding out the threads on the port end of their 9902L adapter are actually 1-1/4” and not 1-1/16”. I could make the thermostat cover taller to accommodate the larger diameter, but the concern is that the thermostat cover and hose end will end up too close to the firewall. If someone could actually measure the clearance between the round water header on the back of the cylinder head and the firewall, it would be helpful.

Yeah, I guess my timing sucks. I’m open to taking deposits and fronting the cost for a few months. I really just want to be assured that there’s enough serious interest to justify moving forward with this.

Skou,

I can get you the total height of the BEGI spacer + Kia Water outlet if that would help. By round water header, do you mean the aluminum press-in fitting that goes to the oil cooler?

Also, here are some pics showing clearance from the BEGI+Kia to the firewall.

Thanks, that would be helpful. This is the distance that I am after.

The Begi spacer + Kia neck is ~2.75" tall without gaskets. I tried seeing if I could wedge something behind that water piece, but with my coils and stuff in the way I couldn't.

Judging from that photo, you might have a total height of 3" to the firewall, but the Begi piece is already supposed to be near impossible to install with the engine in the car.

Anyone know how one would run a hose from the AN fitting to the standard pipe on the stock radiator?

You can also weld AN fittings into the radiator (assuming you meant "aftermarket aluminum" and not "stock")

I never thought to ask, but I take it -16 is fine for this for us? I know on larger engines they don't want to go below -20, but the price of -20 fittings and hose is WOW. MUCH HOSE. SO AN.

Hmm interesting. With my current build, the silicone cold side tube from my turbo compressor touches my lower radiator hose. Was wondering if getting this new part, throw a 16 an fitting with a 90 bend would solve my tight space constriction.

Yeah it would be going to a stock radiator.

Still planning on doing this, but not for a couple of months. Life got in the way. My company is shutting down my office, and I either have to transfer to another city or look for new employment.

edit:good reason, sorry, words in my head weren't making sense that day.
Also, xmas shopping is getting in the way, so 1-2mo's of postponement on my end.
How big is the interest list? I'm one.

Attached are renderings of the final designs I am getting pricing for. The main change is that I integrated the AN16 extension into the thermostat cover so that a separate piece is no longer required.

Hey Skou, this is totally up to you as you are the creator if this work, but it would be REALLY cool if you posted the 3D files for this for those of us with the tools to make this. Seems like it would be a fun couple parts to make anyway.

I just fitted a Begi coolant reroute spacer to a 2001 NB.My observations on their design may be of interst to you in your great project,
The BEGI design seems to be severely compromised by the need to clear the NA type coils. If you have an NB or a car without the rear coils this is bad. One of the consequences is the port for the temperature sensor is oriented way over to the hot side at about 10 o'clock. This requires you to lengthen the wires for the temp sensor.The conductors in this wiring are very fine and fragile.Making a good,durable connection is problematic. Repairing it after install would be very tedious. The BEGI design would be much improved if the coolant sensor port was oriented exactly like the original thermostat cover.That would mean no need to extend the wiring.This has been reported as an issue by others.
One other failing is the bolts BEGI supplied. Over-tightening steel bolts into an aluminum head is a needless risk. It would have been better engineering(IMHO) to supply over-length stainless steel, full thread bolts. Use a stainless nut+washer on each bolt. Run the nut up the full length of the thread to the head of the bolt. Gently torque the bolts in position using blue loctite. Then tighten the s/s nut on the s/s bolt to ensure a tight clamping force on the s/s washer+BEGI spacer + Kia water outlet. Use carefully applied, good quality self adhesive gaskets between both mating aluminum surfaces.
This is what I did because there are reports of the BEGI spacer leaking.If you then try to tighten the bolts they may damage the threads in the cylinder head.That would be a real pain to repair!
We still need a better solution to the EGR tube mod/lengthening required. The CSST solution is O.K. but the adapter fittings are too clumsy and long.
I hope this helps others who make this mod.

Very interested in this. Looks like I may be able to use that fitting on top for turbo coolant feed as I ditched the stock oil cooler/throttle parts.
