6g72 build?

So I have been thinking about boosting my car and have been looking pretty much everywhere without much info. So here it goes.

Pistons? Yes for boost they should be fordged just like rods....I don't find anything listed except for the 3kgt

Rods....oem they say can handles around 400 but stronger is not a bad option, sadly again only find for 3kgt

Next is head to turbo piping....I have 6g oem manifolds to use based on tearstone's build for turbo manifolds and I was wondering about the front secondary o2 sensor location.

Aem wide band o2....best location for accurate readings.
I have obx headers now..if I do not turbo where would be best for the wideband?

Last...egt sensor location, I have the sensor and Guage for an old setup that I parted with. Where is best for the sensor, again both in na and/or turbo application.
Please help if you can. And thanks in advance.

Anyone?.......anyone?
