What size is the LS1 intake manifold?
What size is the LS1 intake manifold?
While the LS6 is a good intake, the manifold developed by FAST is even better. The engineers flipped the LS1 market on its head when it came out with the original 78mm and 90mm intakes. Since then, FAST has made dramatic improvements over its previous designs to bring out its ultimate creation, the 102mm LSXR.
How many MM is a STock LS1 throttle body?

Are LS intake manifolds interchangeable?
Unfortunately, the LS6-to-LS1 conversion is about the only easy or practical LS-intake swap we could identify. In other words, not all intakes will swap with each other. There are a number of hurdles to clear when looking over the list, simply due to the wide range of engines developed from the LS architecture.
