I'm sorry I'm going to have to disagree with most of this.
Turbo cams and cam gears are definetly not needed, there are H22's in excess of 600whp on OEM cams. In order to make use of turbo cams you need to dial them in (using the gears) if you are in a state that has some kind of OBD2 check for inspection this is going to screw you up because the CPS will flip out if the cam's aren't degree'd to stock . IMO not worth the ~$800 they cost (cams and gears).
Balance eliminator kit to hit over 8k. Firstly, you don't NEED to go over 8k and in fact the lower you can keep your rev's the longer the motor will last, and you definetly don't need to go to 8k to hit 550whp, I don't pass 7250 and make 502whp.
Upgraded oil pump, the OEM pump is plenty sufficient, if anything (and again this isn't really necessary) sending it out to endyn isn't a bad idea but not necessary.
Electric WP? I don't know if these are available for H22's but I can tell you my OEM one works just fine at this power level and not sure why an electric would offer you any advantage.
3" Piping on the exhaust side sure, on the intake side 2.5" is plenty large enough and actually fits a bit better and easier to manage 3.0" I don't see as reasonable until you are in the 625-650 and higher club.
An uprated map sensor goes without saying, stocker only goes to 10psi.
A good tune (goes without saying) but C16 is not necessary, in fact 93 with the proper turbo and tune you can make 550. I was going for this but I haven't gotten around to upgrading my fuel rail with an fpr and ran out of injector (1000cc ID's) at stock fuel pressure. I would however upgrade the radiator.
ECT is useful but oil temp is also useful and in some cases more. I currently run A/F, Boost, ECT, EGT, Oil Pressure. these seem to work fine, oil temp would be nice but as long as my ECT's stay under 220 I'm ok with things.
Also I noticed someone else recommended the moroso pans, I wouldn't bother, I had one, it fit like isht so I tossed it and just had my shop weld bungs onto an OEM pan and it fits perfect.
