I thought I'd share my views Between the 2006 Si manifold and the 2007 Type R manifold


^Something I forgot to add, the overall length or height is shorter on the RRC, so this means that the runners are shorter but in this you can see they are straighter too.

Fill them both with water and find out the total volume of each one.

so will this manifold bolt up to a k20a2? if someone where to use this manifold would the karcepts adapter work or would you have to make a custom adapter?

This will bolt up to a K20A2, but would have to be cut just like the RBC, The bolt pattern is the same on the TB flange and the head flange.

Any existing adapter for the RBC will work on the RRC.

The only thing is these are a grip of cash more than the RBC.

manifold is nice but way to pricey. Are you gonna attempt the water volume test?
