Has anyone had any experience using truck intercoolers cut down and used on their cars?

Don't believe the blanket 'Truck cores are crap' BS that is propagated by the aftermarket industry. I've made numerous cut down truck cores and have a good deal of experience with them (made them on the side to fund the crown build-up). There are some types that are poor for flow, but equally there are very very god ones. specific examples are the Garrett and Valeo cores. Both flow brilliantly and have exceptional heat transfer properties (far better than most of the automotive cores available). The last time I saw the JPC VL (it had run 9.23 at that time) it was fitted with a garrett core. In short, look for a core with large passes and a good degree of internal finning. The whole argument that 'trucks don't rev' is absolute rubbish-air is air, heat is heat.
As for the crap cores-as a general rule of thumb, if it came off a Volvo truck-throw it in the bin!
Having said that however, now that new cores have come down so much in price, cutting and welding up a truck core no longer really makes economic sense unless you want the ultimate in flow and size. Just buy a bare core from PWR and make up your own tanks. In the end it'll cost only 100-200 more than a modified truck core.
Take it easy

Yes, there is certainly the scope to ruin a good core if the cutting down and following clean-up isn't done properly. I've seen many dogs of cores over the years when the proper care hasn't been taken. To cut a core down properly is not a small task by any means and requires many hours of work. Selection of a good quality core to begin with is also crucial.

I understand what you mean by getting a trashed core from the wreckers fattony, better off in most cases getting something decent from the start.
It was just fortunate with the core in my car that it was brand new, had been cut down already by a professional to an appropriate size and was a very good price. All very handy at the time, nearly 4 years ago now.
If I was buying a core now though I would definitely be grabbing something from somewhere like PWR and having some custom end tanks fitted up 
Maybe something for the new year..........$$$$$

I have a truck core, its bs about that they are sh1te for flow.
It totally depends on the type of core.
Ive seen some terrible bar and plate truck cores with so much internnal finning htat it would cool nice, but give a big restriction, you obviously avoid such a core.
I run a truck core of unknown origin, and it works fine!
around an .8psi pressure drop.

WTF is that supposed to mean? Explain how it makes a 'sick' flutter? Do you understand what reversion is and what causes it?
And as for trucks not revving, it doesn't mean anything at all, since at 1800rpm they are most likely flowing shitloads more air than any of the 'performance' applications we could build.
Airflow = horsepower. If a truck core can flow enough air for your target power without considerable pressure drop (1-2psi) whilst keeping air temp within say 20 degrees above ambient, then there's no reason to criticise it. There are several truck core applications that match the above criteria, but as said, there are some pretty bad designs too.
Many truck cores end up at the wreckers because of cracked end tanks only, which are almost always replaced for our use to suit the car anyways.

ok. well now i will say i bought a truck cooler last week for $100. it is brand new apart from a few lil dings and scratches.
it is of bar and plate design and compared to the hybrid core the only 2 differences i can see is that the hybrid has offset fins and is 10mm thicker.
the core i have is 870 X 670 X 65 with end tanks on the end of that.
what do you guys think of this core from the best details i can give at this point in time.
also what size should i get the core cut to for my nissan exa 1.8 turbo engine.
thanks

Do you have the standard turbo on it? T2 isn't it?
If so, I wouldn't make it too big. The general consencus is that 600 X 300 is good for modded cars. You want to maximise the front sectional area without making it to big that it creates lag or pressure drop.

Once again, it's relatively simple - if you take the 'cooler from, say, a kenworth with a CAT diesel producing 600hp, and the cooler is providing minimal restriction in that application, then using half of the core for a 300hp car, providing the job is done WELL, is fine. However, using 30% of the core from a lesser powered truck/one that is naturally more restrictive is sheer folly. Trouble is, usually truck cores are bought at scrap metal dealers and such, and you've got no idea what kind of truck they came from originally. However, as said, with the price of new cores these days, why bother?
