When I installed my intercooler I knew that I wanted to also add a CBV and convert to a B23/B230 intake manifold.  Since this setup was more like a 700 series  than a 240, I decided it would be easier to modify the 700 series IC tubes rather than the 240 IC tubes.  I used the metal turbo outlet elbow, IC inlet rubber tube, IC (same as 240), IC outlet rubber coupler, metal IC to TB tube, and rubber TB elbow from a 700 with a B230FTi.

Because the 700s don't have the fuel lines in the way the elbow is mounted lower.  To clear the CIS lines, I extended the turbo outlet hose with a piece of heavy duty blue silicone (1/4" wall, 2" ID, 5" long) tubing form Turbonetics.

Because the power steering pump is rocked so far away from the motor it interferes with the 700 series tube. (I believe the 84-85 700 series tube 'bends' around the PS pump because it had the B23 engine.  This tubing should be able to be used without much modification at all)  To get the PS pump out of the way (rotate towards the motor), purchase a shorter belt, I recommend the Goodyear 17415 (41.5" long).  This belt may also be listed as 13AV1055 (13x1055mm).  There is a small nipple on the metal tube on the TB end that needs to be capped with a large vacuum cap.  Make sure to use a clamp to keep the cap from blowing off..  With the PS pump out of the way install the 700 series IC tube as shown.
