Thread: Defender 300TDI Intercoolers????Links Added

Bit hard to tell a lot from your post. I don't feel inclined to track those on ebay to find out more.

Upgraded intercoolers for 300Tdi, are generally, in order of performance:

Slightly larger intercooler that replaces the stock unit.

Second intercooler in series with the stock unit - usually mounted below below the stock intercooler and radiator.

Full size intercooler. The largest intercooler that can be readily mounted in front of the stock radiator and a/c condenser. The stock intercooler is removed. More difficult if the vehicle is an auto (because of transmission cooler).

There are also air to water intercoolers.

Silicone rubber hoses are better for the heat and pressure.

To get best performance the injection pump and turbo wastegate are adjusted.

Thanks Bush65 for the info....Didn't relise the links were not working ..

i spoke to dirk awhile ago the big intercooler requires ac unit removal ,not that you would notice it missing perfomance of my ac is negiable the small one bolts straight in but he couldnt give me performance increases

I'd also be concerned with engine cooling performance with the full width version, having seen how much the air conditioning condenser blocks air flow in a Defender.

You may need to upgrade the radiator, particularly if you tune up the fuel pump to match the new found potential from the bigger I/C.

I will be fitting a full size intercooler in front of the a/c condensor in my disco - probably in the next 2 or 3 weeks.

Thanks for the reminder Rick - while I'm at it I may as well fit the upgraded disco radiator that I had in my rangie when it had a 300 Tdi.

Who's I/C are you using John ?

The prices of the intercoolers varies a lot. $450 - 1200 on ebay.

Which ones are worth going for?

Also how much is it to get the f/pump tweaked?

Is there anyone in Melbourne that can be recommended?

thanks

Rankin Diesel in bayswater. Make sure you have an EGT gauge for peace of mind, and if the injectors have done 200,000 + , maybe consider changing them before just sending more fuel through them.

I had my 200Tdi Disco done like this and it fairly flew. Can't wait to have the 300Tdi done but the injectors have 220 on them and have a slight nailing under load, so I'll do those first.
