Firstly - Stock engine capabilities.
- What rating is the staandard Ko4 turbo? compresser and exaust size as well as effiency ratings. is the turbo steal turbine and ball bearing?
- Standard intercoolelr - whats it rated to
- standard boost from engine - is it computer controlled?
- Block - What boost level if maintained constently can the block handel before going bang?
- are the pistons and rods forged from factory? (i had someone tell me they were)
My goal is 320 hp ATW and no more. I would like to keep its streetable as quiet as possible (im all about the sleeper)
I know these questions get asked all the time but if you guys could help me that would be great. Cheers!

Hi Aaron and welcome!
You will definitely be able to find more detailed info on these questions on the forum.
Some good answers already, here are mine to the best of my ability
- What rating is the staandard Ko4 turbo? compresser and exaust size as well as effiency ratings. is the turbo steal turbine and ball bearing?
I believe that if you ran 20PSI you would be at the efficiency ceiling, about 18PSI seems to be the sweet spot
- Standard intercoolelr - whats it rated to
There are some members with up to 200FWKW with standard cooler, though there are good gains to be had with aftermarket units in terms of less pressure drop across the core, and better temps
More info here ->http://www.ozmpsclub.com/forum/intak...tercooler.html
- standard boost from engine - is it computer controlled?
For the 3, yes.
about 14.7PSI above 2nd gear
- Block - What boost level if maintained constently can the block handel before going bang?
Im not the best person to answer this question.. you would be wanting to upgrade rods long before upping the boost to anywhere near bang bang territory.
Here is some more info

- are the pistons and rods forged from factory? (i had someone tell me they were)
They are forged, but something about the process being different to true forging..
Im pretty sure Matt has some good info on this one
Enjoy!
