Need you advice/suggestion on my 2013 summer setup

Alright, so im working on my summer setup,

My objectives are rather simple:
-As reliable as possible
-Daily-drivable
-300whp

Currently the car is 95% stock but in great shape, car has 124'000miles on it all original , takes little to no oil at all (maybe 1 pint per month or less, sometimes nothing at all (1000miles) )

Here's what I thought would be nice:
Full 3'' steel exhaust system (SS is not cheap arround here and I would make it myself using a mandrel bender)
CT20B (most reliable turbo that I heard about to upgrade)
Metal headgasket (I have no idea on which thickness I should use though...)
ARP head stud
Moroso oil pan (I plan on using the car for some track day)
Injectors??
Fuel rail??

This is where I need you help, I read alot on this forum and everywhere on the internet to be able to determine what would be the best setup but everybody seemed to have taken a different path...

All suggestion, advice would be really nice from you all!

This site has a nice read http://www.mrcontrols.com/primers/primers.htm
If you haven't read it yet.

This is almost double of the power that the came from the factory so it needs quite a bit of work.

Also try this, to have alltrac make 300whp, look for MR2 with ~ 320whphttp://www.mr2ownersclub.com/mr2records/dyno3.htm

Hope that helps.

Oh yeah the power primer, I follow that guide like a bible

Thanks, yes that helped a lot
