With the intercooler tubing completely welded and bead rolled we were able to connect the intercooler to the engine. HPS 4-ply silicone hose couplings and T-bolt clamps were used to secure everything in place.
Though the intercooler setup is basically complete at this point, it seemed like a good time to go ahead and install the Turbosmart Race Port blow-off valve since it is the last turbo related component that needs to be installed.
The Turbosmart Race Port blow-off valve is a top-tier race component used on many professional race cars. One major benefit is that Turbosmart offers versions of their Race Port with different flanges. For example, part# TS-0204-1104 – FEMALE FLANGE can be mounted to the same flange as the TiAL 50mm blow-off valves
so installing one to an existing TiAL configured system couldn't be easier.
Here we bored a hole in the side of our Greddy cast aluminum intake elbow for the Turbosmart Race Port flange. The hole was sized so that the flange would sit inside the bore. This made the interface between the two components extremely tight for a better fillet weld and decreased the distance the blow-off valve extends off the side of the pipe.
This picture should show why decreasing the installed height of the Turbosmart blow-off valve was a good thing. We nestled it right in between the strut tower and the brake master cylinder. This is about as close as it's going to get to the throttle body without interfering with another component.
All components from today's build are now installed and what do you know, the RX-7's engine bay is finally starting to look complete.
Top down view of the intercooler setup shows just how short the intercooler piping is on this car. It's also nice to see that we still have plenty of room for the air intake and cooling components that we will be covering in the second half of the V-mount cooling system build. It's been a long time coming, but it's starting to feel well worth it.
