EGR Valve Removal

Technical: Discovery I
Uprated Intercooler Installation

Below are a few details of the installation as carried out by Allisports' technician at their workshop.

The old and new intercoolers side by side for comparison.

The larger cooling fins of the Allisport version are clearly visible. They're also longer than the standard ones and the headers are correspondingly more compact.

 

 
The new three part silicon hose kit.

The two smaller pieces replace identical rubber ones between the turbo and the bottom of the intercooler. The larger one is to connect the top of the intercooler to the intake manifold and replaces a rigid pipe with a 'T' connection from the EGR valve that was removed during this installation.

 
The new intercooler mounted in place of the original one.

Because of the reduced size of the headers, the top pipe is slightly higher than before and a small piece has been cut out of the lip of the top retaining plate. This was achieved with a grinding wheel in a matter of minutes in the workshop.

 
View from above of the new silicon hoses in place.

The elbow from the turbo is connected to a steel pipe that routes the air towards the bottom of the intercooler. This pipe is a re-used original part but the rubber cladding has been stripped off to aid cooling.

New hose clips were used throughout.

 
Side view of the new pipes.

The black enameled steel plate used to blank off the hole where the EGR valve was mounted can be seen on the exhaust manifold.

The short silicon hose connection to the bottom of the intercooler can just be seen in the lower left of the picture.
