TD5 removing the EGR

Postby Clive Dennison » 13 Sep 2017 11:36

I have a 2001 TD5 Defender. I am doing some work on the cylinder head and I have the intention to remove the EGR system. I have read that Landrover, themselves, removed it for subsequent models for the SA market.
I don't want the change to be irreversible so I need to buy or make an adapter to go between the intercooler hose and the inlet manifold.
Does anyone know if anyone in SA makes these adaptors?

Good morning.
Earlier td5 engines imported int0 South Africa, were fitted with the egr system, but most td5 engines I have seen are fitted with the blank
Egr valve casting.This casting in line is very restrictive to air flow from the intercooler to the inlet manifold.
Yes it is a good thing to replace the casting with a large bore adaptor, this will improve air flow to the engine.
One thing to remember is that the Map and Mat sensors will still control the amount of fuel metered to/by the injectors,
best mods I have done are.
LAND ROVER DEFENDER 90: 2007 @20 000km now 220 000Km
1.Removal of centre silencer with a correct size and shaped straight through exhaust pipe section .
2.Removal of egr valve (dummy/blank casting) with a large bore adaptor.
RESULTS:
1. Slightly more noise from exhaust but very acceptable (also sounds very good)
2. Turbo charger spools up faster (less restriction/ exhaust back pressure)
I have kept the parts that I removed to do the mods, but I doubt if I will ever put them back in line,
3.one less thing to be removed and cleaned.
4.fuel economy average at 9.6/100km around town much better on the open road.

Hi Willie,
Where did you get the "large bore adaptor" and what did it cost. I am weighing up whether to make one or buy one. If the price is reasonable I would rather buy as I have other things to do with my time.
Our local Indie Landrover man says that changing the intercooler for one of larger capacity makes a noticeable difference to the performance. Have you any experience of this?

You can order it from British 4x4 or Dover.
