I am looking for a coolant swirl pot to go between my block and the radiator return. For the life of me I cant find anyone that makes one to suit Skylines. I thought maybe Sard or ARC do one but cant find anything. Those ARC ones I saw for other models suggest custom is better.

Anyone have any ideas?

Is your engine breathing much Roy? I noticed the Gibson 32's ran a fairly small one, but the Sierra's ran an 8 or 10 litre pot. They must have had a lot of issues with air in the system.

I have a Chinese one here to fit, just run small hoses to all the high points in the cooling system and the lower return to the bottom radiator hose or radiator drain bung.

Since putting the plazmaman plenum on the car its a lot harder and time consuming to bleed properly. In the coming weeks I will be changing turbos a bunch of times meaning dropping coolant etc and CBF having to do time consuming bleeds each time.

So looking to grab a Greddy Header tank and connect to a high point of back of block but also want to connect to the return line. Not stressed if I canf dins anything as I will be connecting to the top of the radiator...but the radiator isnt ideal due to the top tank shape

This is what I am looking specifically for....though nozzles orientated for a Nissan

Roy i have a GREDDY and well worth the stuffing around to get it running....

i removed my overflow bottle completely and run the breather from rad straight to the top inlet on the swirl pot.

Bottom outlet goes down towards the heater section

2 side mounts are on on the top of plenum and bottom of plenum.

i can get some pics if you want as im running plazmaman aswell :)

So where do you pipe your overflow to when it gets hot ? Nowhere if I read correctly?

with the greddy its virtually its own overflow so if it does blow through it goes straight back into the swirl pot...

the other way i have seen it done is remove the rad cap (or dont have one) so that pipe actually becomes part of the cooling system so its a constant flow of coolant from that top port of rad to the swirl pot

The latter is what I am familiar with. You put an atmo reservoir cap on the radiator and you run your 1.3bar cap on the swirl pot which is the highest point

I guess I will have to put the in line swirl pot on my list of things to tack up for someone else to weld up for me :( Just isnt enough time and money with farging cars :)

Scott...my understanding of why the Gibson R32 ran them is because they had lowered the radiator to fit the air intake above it. So they had to run a small to stop air pockets forming in what otherwise would have been high points in the engine. The Cossies run a larger one to boost capacity as they also run separate alloy coolers for just the turbo water line that goes from the turbo, to the cooler to the header tank

The only way to do it properly is as per the diagram above.

We weld up the radiator filler hole and use the header tank to fill.

-4an fitting from highest point of the radiator to the header 1.5in from the top

-4an from the original cylinder head bleed point to same height on header tank.

Base of header tank T'ed into the lower radiator hose heater hose or the lower tank of the radiator preferably.

The swirl pots that are only there to create a new high point. The swirl pot in the top hose should still bleed its highest point to a header tank

can you make something like this for r32? whats the cost? im sure Roy would be keen on one aswell?

That's the setup I am doing Dale, how is yours going?

Slowly. :verymad:

Too much time at work; not enough time with shops open...

​Got a couple more fittings to pick up; than I'm good to go. Hopefully Monday.

Also, apologies to Roy; I wasn't being a smartarse, but I had the pic handy , and didn't get time to edit with an explanation.

I fabricate those all the time. Pretty much every GTR I've built to be raced has a header tank and swirl pot system.

The swirl pot alone is $180, at the moment I'm closed for a week so nothing will be getting fabricated before the 15th

    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
