Coincidentally I already have one of those in average/good condition and it looks like it should mostly fit with minor alterations.
And Jeremy is correct in deducing I want this simple, clean and reliable. Not getting into crazy setups or complicated systems, the least amount of things that can break and go wrong, the better.
Standard air intercooler is the ticket.

There are a few http://item.mobileweb.ebay.com/viewitem?itemId=300915358484&index=11&nav=SEARCH&nid=49137045286
That is the cheapest I found. The Volvo one would work good for a front mount, if i remember right they are very thin too.
The ford cooler is not ideal but would work, the volvo in a front position will work better. The ford one we have is planed for Gavins 1.6TD 74 westy or the turbo HJ60 depending on what happens with them.
Would you need a fan on that, no? I can't see you getting enough air through it to do the job without one.
The other thing to think about is flow and in this regard intercooler inlet and outlet size. Already you are loosing boost by the number of bends you have. I think ideally the intercooler inlet and outlet should be as big as that of your turbo.
Possibly need a fan, had to know with out testing it would also greatly depend on the placement of it and the scoop on the hood. In the VW van we plan to use it in it will have a fan since its in the rear with relatively little air flow.
Flow in regard to the inlet and outlet is moot the inlet and outlets are far bigger than the turbo compressor outlet on the 2LT or any other small diesel sized turbo. The number of bends is greatly reduced in a top mounted cooler as well as the length of pipe (less volume to compress). Any water air core would have arguably the same pipe routing depending on size and layout of core so I'm kind of missing your point here?
Actually I'm not sure what your point is at all now? You started touting WAC and how it works so well on comp trucks now I'm a bit lost where you are at? Are you saying now that front mount is the way to go? If so I agree if you have the space but as Mat said in his fist post he was not sure he did so simple moderately effective options where suggested.
Glenn water/meth injection can be very effective bit its a consumable and on a diesel that is usually always running a good amount of boost they can drain most systems quickly. On my Supra it allowed us to run 25psi (596whp) on pump gas, with out the water meth we where limited to 18psi (480whp). So its got its place just not sure this is it.

Granted I have not done the math on this ....and I really don't want to but if all else fails I will... Air loss due to friction of the bends, the additional travel and restriction of flow due to fins and smaller passages should equate to around 20% in most intercoolers. So if you are running 20PSI out of the turbo, by the time you get though everything, you should have 16-17PSI at the intake. Granted, tube size, amount of bends, size of channels in the fins, length, will all change that outcome a bit, but that is an average estimate.

Raises his hand......why not skip the intercooler altogether? I don't have one on my truck and frankly, it pulls a heck of a lot better than before the turbo which suits me fine.
The 2LT probably has 85HP? (according to Wikipedia) How much difference will the intercooler really make anyway?
Are there other mechanical advantages to running an intercooler? (less wear on parts, etc, etc).
Great discussion, carry on.

For the full description of what it does you can look that up on google, as for the benefit, especially in this case, other than the obvious more efficient combustion of the already existing fuel/air it does keep the temperatures down. This being a 2LT with a long standing history of blown heads due to heat, I figure it would be beneficial to help that as much as possible.
I don't know know what kind of "performance" I can expect to gain from this but I am sure it will keep the EGTs down.
As for the 3B, will it help? Yes of course. Will you notice it? Likely a little. Is it worth it? Possibly.
I know this, in the summer, during the day when the truck was hot it performed like a regular 3B with a turbo. On cold mornings, with ambient temps being 10-15C cooler the truck actually did have a little better performance. Faster acceleration and more power, marginally, but enough to notice.

All I know is in the heavy 60, the turbo 3B gets hot, I am changing out the rad to a 4 core, new thermostat, and new water pump as we speak, but if this doesn't solve the overheating issues on hills, I am going to go with intercooler. Exhaust temperatures climb pretty high and I could lower the amount of fuel I am pushing, but where is the fun in that
I have read some good things on the Victoria club page where some of the 60 guys were really impressed with pulling hills after they installed front mounted intercoolers.
I'd still want water to air from what I have read. But people do what they can afford, including myself. My budget would also be air to air. I'd have to do some math to figure out if it would be top mount or rad mount. It isn't just as simple as routing with air to air either. It is pipe size, bends and also the flow capacity of the cooler.
I think the big thing is cost benefit. Spend 2-3 times as much for a WTA system that preforms at best as well as a front mounted ATA system. I'm giving the WTA the benefit that its designed well with a large capacity of water and a very efficient heat exchanger (this is very often not the case). So you are spending 2-3 times more for a WTA, that preforms the same as a front mounted ATA but is also much more complicated and has multiple failure points, relies on power for pump and fans plus takes up a lot of space for components (water tank, piping and so on). Yes the piping is shorter on the WTA but at the cost of complexity, I would be very surprised if someone felt a difference between 4ft of intercooler pipe and 1-2ft on a diesel. All the issues about pipe size and so on are the same for both WTA and ATA.
Yes, but WTA is less restrictive on air flow because it is so efficient. Air does not have to flow around as many fins. Hence your boost drop in a WTA is much better than in a ATA with the same size and length of piping and hose.
Deny, lots of top mount Pajero intercoolers with fans for topmount on fleabay. This one is a good price http://www.ebay.com/itm/MITSUBISHI-...arts_Vehicles_CarParts_SM&hash=item338252ed9a
It all depends on the core, cheap WTA cores will be just as restrictive. It also depends on the amount of air being pushed through it. At the stock boost levels that Mat is working with ill bet the difference is minimal at best mabye .5psi non intercooled vs intercooled. Most of the WTA systems I have worked with do have very little boost drop but there efficiency is not the greatest even with a large reserve of water they are very prone to heat soaking and there efficiency drops like a rock when that starts to happen. Where is your experience with this stuff derived from?
Where else? ....from people like you on the weeeeb and forums. ;p
