how do they go with overheating when worked hard and has anyone looked at Exhauts gas temp,just the mention of the need for a big intercooler has me wondering
I have experience with the 300Tdi, but not in a 130.
I don't think engine overheating will be a problem, unless the cooling system needs attention (radiator needs rodding out etc.).
However, these engines are easily damaged if coolant is lost (partially because the water pump is very high, and because of relatively low thermal mass compared to heavy duty diesels). The aluminium head is what suffers - loss of bolt tension after an episode of severe overheating leads to head gasket failure.
So adding a low coolant alarm is highly recommended.
A bigger intercooler, will be beneficial (is recommended) if you increase the boost pressure and fuel (both relatively easy). But you do need a pyrometer to measure EGT if you play with the fuel (especially for a tow vehicle).
However I would strongly recommend a cooler for the manual gearbox (some models have these).
AFAIK, autos were never a option in Land Rover Defenders (only disco and rangie). A disco auto could be fitted, and these can be upgraded for what you want.
I can't disagree with anything in the previous replies.
A chipped TD5 130, with intercooler upgrade, will have a lot more power and torque than obtainable from a 300Tdi.
