As a note, the 75mm version has provision for EGR where as the 90mm unit does not.

Can't really use that intake to its full potential can you?
How much RPM can you turn with a stock block and internals?
With it's intended use, my suggestion would be the smaller version. If plans are subject to change down the road, won't hurt the combo that hard to use now.
