This was such a fantastic video; thanks for posting! I'm building a 1977 Datsun 620 pickup with a KA24DE-T swap and I want to go air-to-water because I don't want a giant FMIC screwing up the looks of the classic front end. My water tank might end up being even smaller than yours because I'm going for a realistic, 250 whp, bullet proof daily driver!
Ah cheers mate, i wasn't sure if i was going to make a vid on it or not but people seem to be interested, been quite a while now and it's all going strong, i think i'l do some refininig on it though, put a bleed valve at the top of the tank and a few bits like that but it's still going strong :)
"There's your answer" 😂🤩
Great job mate, looks mint 🤘
i'm sure yours will make mine look like it's duct taped together!
@@TheNuggetProject gah it's all relative - I'm dreading what my 3D printer stuff will be like 🤣
With the airbox fitted and the top bracket sexyed up it'll be an awesome looking engine bay.
Tidy work as always.
cheers man, bit of a mess of a video but it turned out alright, will try to make the next one a bit more interesting with a drive etc :)
That pump is not man enough fire the job.
It’s a parking heater pump.
Look out for a Bosch “010” pump , it’s used in the supercharged Mercedes , it’ll do 4-5 gallons per min . They’re cheap .
Also those 90 brass fittings are absolutely terrible for flow . Use the ones they call “smooth radius or smooth flow” fittings for nearly free extra water flow.
Love the build .
Cheers mate, this one is flowing alright but i'll look out ofr the bosch pump to upgrade in the future :) and yeah the brass fittings are pretty average, i should be able to get a deal on proflow or raceworks stuff at work so i'll get some nice bend fittings. a lot of this was purely to get it all doneand working and i'll tweak it all as time goes on :)
Cheers for the advice
Doesn’t need a flow rate like a radiator mate…. Just needs constant circulation, can be on boost for quite a while before it heats the water enough for pumping…. Could always put a thermal switch into the relay for temp trigger the pump……
Nice work😀
cheers bro, bit of a boring vid, such a mess over 9 months haha
I would have put the air to water heat exchanger between the rad and the timing cover, flipped that turbo pipe around on the turbo out let and then you dont have to do a 180 degree bend in your air flow plus you shorten the boost run which will improve boost response time.
very nice job though
if you want to take it further, you should look into an interchiller set up which uses the ac system to cool the water to sub freezing intake air temps which translates into more hp.
Hey mate yeah that was my original plan but I just couldn't fit it in there, tried a bunch of stuff and even if I ditched the thermo fans all together it wouldn't fit, there was a smaller cooler available but it was rated for much lower horsepower so I ended up going thr way I did, not perfect but it's just the way it ended up!
I'm going to replace all the dodgy fittings with raceworks ones for better water flow. See how I go with the AC chiller, it's just a weekender so no drag racing or anything :)
cool build . It could end up with a air lock in cooler . If you unbolt and turn on its side or put an air bleeder in top . I think could help
Yup exactly what I did when I did my final bleed :)
I may have misheard you it the water temp probe for the fans needs to be in the top radiator hose 👍
The fans are controlled by the ecu from the factory water temp probe, the temp probe in the top rad hose is just for an aftermarket gauge :)
I really like this setup ,but my issue was I can’t fit anything in the front as I don’t have space for intercooler. In this setup the heat exchanger as big as my intercooler itself ,so it doesn’t make me fwd with my built too much. I need to find a space for the heat exchanger somewhere
yeah i've got tonnes of space in thefront bar, was easy, fitting the cooler in the engine bay was trickier
Hey what water pump did you use? Just did a very similar setup in my Subaru but I'm getting cavitation with my current water pump, I suspect it's oversized.
Hey mate I got it in the kit with the cooler, let me have a look and see if i can find a brand :)
You will have air the water to air intercooler need the water line top and bottom. You will have air from the fitting to the radiator cap unless you can pull a vaccum and inject coolant in system.
I unbolt it on the final bleed, twist the cooler and put the cap above it :)
Compared to the air to air intercooler, would you say the air to water keeps intake temps lower?
Cheerz
I'm putting temp probes in soon so I'll let you know!
@@TheNuggetProject that would be great.
I would like to know if that size air to water cooler is more efficient than that large air to air.
Air to water is easier to install and running smaller water pipes than huge air pipes.
Also keeping the cooler closer from turbo to intake, will result in less turbo lag.
An additional heat exchanger will also improve cooling of water and is an easy addition should the need arise.
Thank you.
any update to the water to air intercooler.
So I still don't have the new gauge setup in there with the temp sensors but as far as reliability and functionality goes it's great! Took the car to work today as it was sunny, then went home via the mountain road, pulled over after a bit of a run, popped the bonnet and the cooler is still ice cold! Seems to work great. I just got my racecar sponsored through raceworks so I'm going to hopefully upgrade the fittings to nice raceworks ones :)
Is there a kit you used or did you buy the parts separately for the build?
So there is a guy who puts kits together in eBay, I think he's a part of fenix radiators, I had to buy a few more bits and change fittings etc, but it had most of the basic parts I needed :)
what filament are you using to print things for the engine bay?
Petg, as long as it's not near or above the exhaust manifold it's fine :)
Hi, can U tell me where I can order that expansion tank with the cap? Regards
Just got that on eBay dude :)
@@TheNuggetProject but how do U call it? I'm Spanish and I don't know it's name

@@TheNuggetProject Thank U!
What type of water pump did you end up getting. Will be doing a water to air for my e30 turbo.
i'm not sure on the brand mate, it came with the kit, i think its a pretty basic one but seems to be going well so far and the supplier said he's run them for years in the cars. there is quite a bit of info online about pumps, i believe there is a bosh unit used on mercedes that is really good, have a google see what you can find :)
@@TheNuggetProject yeah usually these kits are pretty decent. Even a budget set up runs well. A Bosch unit usual are merc/audi/ terminator cobra here in the US. $150usd and knock off style ones are half that. I've seen some people run small reservoirs also.
Yeah for sure, we have a drag car at work with a similar system but lines run to a 20 litre ice tank in the boot, that really keeps it cold! But for daily duties I think it's fine how it is on this car :)
@@TheNuggetProject good to know. With a conservative 300-350hp I'm sure it'll be more than enough for my car. Good to know you're happy with it.
Cheers bro, now I just need to find time to finish the dam thing haha, got a small vibration to sort out, the camber is all over the place, clutch needs bleeding again, new gauge system needs to go in... The list never ends, meanwhile the daily is leaking all over the driveway haha
How did you bleed air out of the cooler? I can’t help but think the upper part of the cooler is just an air bubble and not flowing coolant.
Undid the mounts and rotated the cooler around so the exit fitting was at the top to get the air out :)
I may drill and tap the top of the cooler at the highest part for bleeding later on :)
@@TheNuggetProject ah ok, fair enough.
I’m surprised such a small pump is sufficient enough for water flow inside your loop. Have you looked into flow rates etc..?
Na not yet mate, i've bot a bunch of sensors that i have to wire up to check water and intake temps but haven't got around to it yet. it actually flows pretty bloody good for what it is, you don't want it to flow too quick as the water doesn't stay in the head exchanger long enough to cool down (same problem you see with racecars that have water pumps that flow too fast)
absolutely dude, too fast,and the water will flow through that small system too quickly, in my opnion, the only thing id add is some heat shielding to the core as to not have the engine cook it, but if you say its working fine, then no worries
@@TheNuggetProject
@@CrameroftheCreek yeah good idea, I want to rejig the cooler a bit and update since pipes I'll look at it then but I've got two other project cars that need my attention first :)
This is very old technology the world is still using the old technology because they are not thinking about more efficient less space occupying one
sooo you think it's a good thing? your comment confuses me.
Yes water to air is an older tech, but straight up i just wanted to do it because i've never done one. Unless you are talking about the whole engine, i really don't know.
Just because something is very old technology, it doesn’t make it bad technology.
