i am looking for info on the stock turbo ii turbo,specificly

1. who makes it

2. does anyone have a compressor map

3. what is the a/r on both the compressor and exhaust side

4. how much power are people making to the wheels on the stock turbo



thank you, and sorry for the newb question.

 

1. hitachi

2. no

3. the a/r on the exhaust side is about 1.0

4. it will do about 255-260rwhp

 

to4B s-trim compressor graph is supposably identical to the stock turbo's.
