3rz Turbo Conversion. - I'm running HKS Planum (water to air)

what have you got cooling the water in that system?

is it a separate system?

make sure the pump is working, the metal will also get a fair bit of heat soak from the running engine

Is this the lux that got covered in paint stripper? If so, I was the lucky bastard who took your roof back to bare metal and got it smooth again lol.

Just like your engine cooling system the hoses and plenum are going to feel hot to touch although may be working as designed. The only way to tell for sure is to get a temp reading...

Ive only just got the ute, but it has a fresh re-spray and i was told the roof was dinted from previous owner using it as a seat...

so it might be... altho i wasnt told about paint stripper....

It doesnt have a pump, and its running with coolant thru the system.

Like i said before i only just got it, and dont know that much in regards to turbo... and everyone that does know, is almost confuzed why its a water to air system..

Ive booked in at Chiptorque in Nerang for them to have a look at it.. its running fairly rich...

Basically i just wanna know if it will run better with a front mount.

That's a pretty small intercooler regardless, so a decent sized FMIC would cool things down heaps more. Won't 'run better', but you'd make a bit more power. I've never been a massive fan of water to air coolers, but apparently they work, just always thought air-air ones were more efficient...

What's it tuned by? i.e. ECU.

Sounds like the one, was running rich when we had it at the shop to...

would need a pump to curculate the water better if its 4x4 id get the water to air working as they give a consistent power increase not as efficent as a air 2 air but better at low speeds say under 40- 50 km/h or if its 2wd a air2air would be better suited check out (are cooling) its good reading they are on thenorth side and seem to realy no what they are talking about they made near 1000hp atw with the same motor you have in the hilux give em a call

your first problem is the cooler is sitting right on top of your engine where all the heat is ... so cooling wont be at its maximum and hp will be affected ... try relocating the cooler or fitting a front mount which should help inlet temps

Your intercooler core should be big enough for the job provided its getting decent temperature 'coolant' and flow through it.
Looks like you have identified the problem with it running presumably engine coolant and no pump.

You absolutely need to separate your intercooling system from engine coolant system if that is how it is now.

-You need a pump to push it around your system - 12v bilge pumps work fine and are cheap to start with but there are more expensive pumps specifically designed for W2A applications out there. Something rated around 20 gpm (gallons per min) is normal. You mount the pump as low as you can as they 'push' well but dont 'suck'.

-A separate 'radiator' to cool your W2A coolant. If you dont have air con any more you can put it where the aircon radiator was, otherwise fit it where you can, it wont be nearly as big as a front mount A2A intercooler so it should be much easier than trying to fit one of them.

-It's also a good idea to have a small reservoir mounted high up in the system so you can bleed out the air easily.

It doesnt really matter in which order you connect your reservoir, heat exchanger, intercooler core and pump but I have mine like this:
reservoir -> pump -> intercooler core -> radiator -> back to reservoir.

The intercooler core you already have can be the most expensive part.
Pumps should be cheap and easy to find on ebay/internet.
A small radiator from a charade of other small car should be cheap and easy to fit. A mate with a welder is handy for modifying end tanks and welding on fittings but Im sure you could find a shop to do that easily enough.
Reservoir doesnt have to be elaborate or you could probably get away with drilling and tapping a hole in the highest part of the system with a plug.
You dont need to go nuts with aluminium fittings or braided line and other expensive pipe. I used simple 3/4 inch internal diameter silicone tube for most of it bar some 1 inch internal diameter line to feed to pump.

Properly working W2A will definitely cool just as well or better than A2A - at 400whp on the dyno I had intake air temps at the throttle body of 1-2 degrees more than ambient that day run after run.
Add to that no pressure drop across the core like you might get with A2A and no hacking up the front of your car to make A2A front mount fit.
The cons when compared to A2A are : more complicated (which can include more to go wrong), a little more expensive depending on how you do it, and adds a little more weight.

There are plenty of websites out there explaining this further than I have. W2A is popular in USA and with the strength of our dollar compared to theirs I would look to getting stuff from there either through ebay or other online vendors.

Couple of years ago I worked out my whole system and got most of it through here http://www.emspowered.com/storefront/index...;cPath=45_12_14 which caters for mr2's well and a bunch of fittings and other stuff from other USA vendors. Was much cheaper than buying in Australia and this was when our dollar was only about 70 US cents.

wow, awesome information.

was not expecting this much assistance.

Im hunting down a pump from ebay now, and im looking at moving the planum. thanks for all your help.

hey mate it actually has a pump have a look in between the grill its red and white this system works very well turn the ignition to acc and you will hear the pump work then add warter into the cooler it will start to fill up like i said the guy who owned it after me didnt like doing matinence to it that should solve the problem but a front mount would proberly get you better top end power whitch it is lacking hopefully that should help you out if not give me a bell and ill help you out.
