I assume we're talking about the old turbo-diesel engine, and if so, while
adding an interecooler (or a bigger one) is an excellent plan I'd be wary of
trying to up the power or boost too much on that engine.
By intercooling, you lower the charge temperature, which is good. Having
done that, you get the chance to up the boost a bit, and up the fuelling
accordingly, and get more power. The main problems you get with doing that
without the intercooler are down to overheating and the risk of melting or
burning pistons and so forth.
Basically, with that engine, and at a high mileage, I'd take it a bit at a
time and keep a keen eye on the operating temperature.
Same applies to any engine, in fact - if you increase the power over the
manufacturer's settings, you risk losing reliability/longevity.
