Now lets say I got a turbo kit, and ran it at 8 psi on a stock motor with a good tune and made 215whp. Then I decided to get a highly ported head with stage 2 cams... Can I add this with a stock bottom end since I am not cranking up the boost?

As long as its tuned right and has oil pressure, the stock bottom end can take some abuse. You will still be alright after head work. Id consider the Crower 2 Turbo grind cam, as with a standard Crower 2 its designed to overlap to pull in as much air as possible, and with a turbo you will be pushing a lot of that air into the cylinder and out the exhaust valve.

Parts are generally not rated by psi as much by horsepower/tq (and that's a rather loose rating because of the many variables in rating parts). What I am trying to say is you are still adding power and being turbocharged would be adding it at a more rapid rate with mods. With the being said, I would worry about the rods and the clutch with that kind of power.

Ok, Thanks guys. I was wandering about the results with adding power though bolt ons, without uping the boost, on a stock bottom end. So.. pretty much forge the pistons and rods.

Im still on my stock bottom end on 10psi daily with a pretty big port job and I could definitely feel a difference after porting the head as well as a larger throttle body. I didnt dyno though.

Well when I got my car I rebuilt the engine with all stock internals with race bearings and Turbo rings and arp headstuds. At around 20k miles I put the Turbo on and I been Turbod for the past 4 years on the same setup.

Stock motor on 7-8psi, as long as you have adequate fueling, is perfectly fine.

Yes it is my DD. But i really dont push my car at all during daily op. Usually keep the shifts under 3k unless im getting on a ramp for the freeway; then i bilieve it is safe to say everyone feels the temptation to go WOT
