just wondering what psi could you pump into a stock internal ca b4 doing internals?

How long is a piece of string??
It depends on many things. How good the tune is what condition the engine is ect ect.
I would say with a good condition stock engine and tune 15psi should be fine anymore the stocko pistons will probably fail might last for a little while with more boost but again it really is the luck of the draw.

most tune shops will say 1 bar but i hear a lot of backyard drifters say 12 psi or 14 psi is ok

would this be with a stock turbo or upgraded? just out of curiosity.

lol why not put a a12 in it and run 20psi with stock internals lol its been done evan more up to 30psi on this site

lol does it matter what turbo just asking what pound lol but its a hiflowed t3

when you go a bigger turbo the psi is how you say stronger ? or something

The word you are probably looking for is efficient. This is true, it does depend on the turbo not just the reading on your boost guage.

To attempt to run 14psi with the stock turbo to redline would be pushing the compressor right out of it's efficiency range. This means you get increases in inlet air temps and less power compared to a larger turbo pumping that much pressure at a cooler temperature.

thanks boys any more info . . . . ? just want to know as much as i can

I think there are a bunch of good technical articles on turbocharging at the Garrett website that could help yoy in knowing as much as you can.

I remember ca18det_man pointing them out when he bought his new turbo.
