Thank you, next tested would be to find a consistently available turbo header so make a complete turbo kit

Empi's manifold doesn't have preheat all the way up to the base of the flange. Manifold heat is key for peak performance in our opinion

@@red-emotorsports1212 Thanks for sharing. So for a large displacement motor that doesn’t have heat risers, would you recommend against this kit? I’m planning to put a 2180 in my beetle with a Gilmore a/c kit. Dual carbs makes an already tight fit even worse in that case. Would love a center mount option.

It's more hp based than displacement, but we would venture naturally aspirated through stock end castings to be limited somewhere around 130-140hp?

That's what comes with the Redline manifold.
