msp manifold flow vs stock ported

[mrmoose]

anyone have a flow chart of the stock manis(besides the word restrictive in bold) and the msp manifolds. I am running ported stockers and they seem to flow great after the internal polishing. just want to see if the msp manis would be an upgrade or waste of cash. and i have a feeling mine are on borrowed time, walls are pretty thin.


Also just so i know, do they mount the turbo and lower or higher, i see a lot of kits saying the msp manis are needed for proper fitment?

I think I saw a flow chart comparison on tt.net or on Australia's 300zx forum, I remember seeing a comparison between the 2 you list, OEM unpolished, and another (maybe Inconel?). Google and do a little more searching, it does exist!

The MSPs mount the turbo in the same place as OEM. It's a great upgrade to any size turbo.
