some things never change..lol.
As with any setup, pros and cons need to be measured out for what you need and want out of the car. Going top mount has it's benefits, but it also requires more initial investment to get everything going, while a bottom mount you can install in a weekend without having to buy a downpipe , custom lines, and intercooler piping.
(andy - does that top mount T2 need a custom made downpipe, or does the full-race 3" V Band downpipe work..that is if you're using a B.W. EFR)
A lot of guys go with the Tomei not just because the "cool jdm factor". They are reliable, well designed, and as a big selling point, come with all the oem nissan gaskets and hardware you'll need for the installation. ..If I remember correctly, I think they even come with a mls (multi-layer steel) manifold gasket.
Again, these are all individual choices, based on individual needs. Good luck with the hunt for what you're looking for
