would this work?

was just wondering if a universal 19 row oil cooler cood be used as a radiator for a water to air intercooler....... have been told "no" but i didnt get an explenation... can anyone explain why please? i have a subaru EJ20 water to air intercooler i want to put on my toyota 3B ..... if you know of another radiator let me know please...cheers!

as long as the material isnt susepatable to corrosian etc id say go for it

otherwise use a motor bike or very small car radiator

I used a transmission cooler as a water to air radiator for years on a 2ltr turbo engine. As long as it flows well I cant see a problem. I've heard alot of people tend to use small radiators like mini or early corolla but I just didnt have the room in my particular application. BTW, I ran 18psi all day everyday.

What other OEM water/air coolers are available? I was only aware of the subaru ones, but would they flow enough for a 4L diesel running ~8psi boost? If so what shape are the suby ones? Where do they fit? How much are they worth?

I had a 87 FWD Celica. I transplanted the Turbo GT4 engine into it and used the water to air IC that came with it (ST165). It looks like this:

As said I used a transmission cooler instead of the original radiator (wasnt supplied with the engine). Mine handled 18psi with no probs so I cant imagine 8psi would be a problem as IC was designed for about that from the factory boost setup. All comes down to the speed your water pump (for the IC) flows at. Too fast and it doesnt stay in the radiator long enough to cool.

More info here: http://www.alltrac.net/tuning/intercooler.html on my IC as well as the later model GT4 which was a bit bigger and more efficient. Might be some decent info there for you as it gives sizes for the standard radiators used for each model.

there is one of these on ebay at the moment

If you're worried about corrosion just run coolant in it instead of water.

Don't suppose it matters which end is in and which is out? (for air)

You would run coolant with water, not straight coolant.
Coolant (glycol) has very poor heat transfer, but good anti-corrosion properties.
Water has the best heat transfer of any readily available liquids you can stick into your radiator/heat exchanger

Ben?

Are you gonna enter this one?

I assume you meant what HotFour said??? He is entirely correct - pure water is a much better coolant than water+ethylene glycol. The only reason we don"t use pure water is because of corrosion and freezing problems.

So to help MUSS - a small radiator, or all cooler are all heat exchangers and anything put in there will work to some degree. Like any heat exchanger the biggest (and most efficient) one you put in there will work best. Keeping all the metals in the intercooler and the radiator the same (and non-corrosive) will mean you can run pure water to make it work more efficiently.

So just about everything except for the intercooler and air hoses??? I am interested - let me know.
