I don't really see the N20/N26 comparison as being a big deal. As mentioned, its the same engine with a higher restrictive Cat/downpipe being the biggest difference. As for suspension...KYB shocks/strut systems seem like a popular upgrade. Brakes can be upgraded for about $2200 to the M-performance setup but I think just changing to a higher performance pad will net you the same improvement. I have stock base brakes and they haul my car down from speed pretty fast...
