my gsr has 76,000 and i run it to death. i just got it dynoed and she has 155hp at the wheels. Stock gsr are suposed get around 156. I have aem CAI, dc sports 4-1 header, and apex n1 catback, and type r wires.im planning on doing a rebuild by the end of summer then im thinking of turbo. i was planning on new piston rings and lower compression pistons. but im not sure yet. ne1 have ne ideas off what i can do to make power?

 

Depending on the amount of boost you plan to run you may need more than pistons to prepare then engine so that it will be reliable...

 

id actually recommend that you do a compression and a leakdown test right now.
