Re: Z6 MANI SWAP (Bigjon)
i didnt see what u were directing me to. i went through the whole thread and didnt find anything about a y8 mani on a z6 head. does anyone have a clue about this? form my understanding the y7 or 8 mani has bigger ports and alows more air flow. i am pretty sure it bolts up . but i need to know what else i might need.

Intake: Obviously you should already have a tubular intake (cold air prefered). But, what sized intake pipe do you have? There have been dyno sheets that show a 3" pipe leading to the trottle body makes the most power. Once you get to the trottle body, you need to upgrade that too. Almost all honda
trottle bodies will fit onto the D series intake manifolds. The newer B series trottle bodies are all 60mm in size and of course the Type R is 62mm. The H22 is also a 60mm trottle body. While the Civic gets a puny 56mm. Up next is the intake manifold. For that you want the D16Y8, often referred to as the Type R manifold for the D series. It has short huge runners and a large chamber to allow the air to distribute to each runner properly.
Also, for the non-vtec guys out there, it has the common horizontal trottle body, which will allow you to use the larger CAI's (cold air intakes). Once you get all three of these upgrades, you should move onto the exhaust side.
My bad, I linked the wrong one.
