Intercooler piping

When I was doing research (browsing the web looking at cool cars) on how I should route the intercooler piping I noticed that just about everyone seemed to think it was necessary to relocate the battery, cut the bumper supports, and cut holes in their fenders.  I didn't want to cut the bumper supports thinking "If I ever get in to an accident I want all the front bumper strength I can get."   So after pondering for a while I decided while not ideal for ground clearance. going under the car was my best choice.

After a year or so of driving the car with the IC piping going under the car I am pretty happy with it.  I have scraped it up a little on one side but nothing major.  I just won't bother polishing them.

So on with the pictures.

Here is the hot pipe coming out of the turbo.  It's hard to see the top of the pipe, as it is partially hidden by the distributor cap and wires.  The output of the turbo is 2" so I have a 2"-2.5" reducer on the output of the turbo that feeds directly into a 2.5" 90 degree bend.  The pipe runs about an inch over the frame rail leaving plenty of room for engine movement.  Notice that it doesn't clear the power steering pump bracket by much.  It doesn;t have to because the PS pump moves with the engine as does the pipe.  Excuse the inconsistency of the welding.  I'm not a professional.


More on the hot pipe.  Here are a couple of pictures showing how it goes under the car:

Then the air goes through the intercooler:

Here are a bunch of pictures of the cold pipe.  The last picture shows where I put the idle air feed.
