LS6 intake & WCC TB INSTALLED!
Hello everyone I wanted to share with you some of the details involved with the install of an LS6 intake manifold with a West Coast Corvettes throttle body onto my 99 coupe.
I will start out by saying that this project was more challenging than I was expecting. If you have ever installed an intake manifold before you can handle this but I would not recommend this project to beginners.
There are a few methods for this mod and I chose the path of leaving my cooling lines intact and modifying the bottom of the intake to allow clearance for the cooling lines. This was not as simple as I hoped it would be. On the bottom of the intake manifold there is a backbone style grid that criss-crosses the bottom. I used a dremmel tool to grind down a path thru the grid. It was necessary to remove over half of the grid and about ten "test fittings" in order to gain clearance and then the manifold finally dropped into place.
During the removal of the original intake I did not disconnect the fuel lines from the fuel rail. I was able to gently move the entire fuel rail with injectors over far enough to be out of the way. The rest of the installation details are easy to find on the forum so I will not go into the rest of it but I will stress that you need to pay very close attention to the tiny vaccuum port in the very back of the manifold. If this comes loose during the install you will never be able to see it once the intake is on so be very careful with the connections in back or you will be doing it all over again. I also took the extra step and bought new gaskets for the intake ports, old ones were kinda flat.
Start to finish was about 4 hours and the car started right up and idles and drives perfect! I have no hp numbers but my car feels very smooth and feels even stronger on the hwy.
I want to give another big thanks to my friend Benny (RamonaC5) for selling me this setup for a price that was so low I do not dare say it on the open forum. Thanks Benny!
