Okay I am purchasing the Nismo Exhaust Cold Air Intake and Headers. I am just curious about the amount of hp I will gain and will I be able to feel a notiable difference in power/performance?
Thank you.

 

Is this in the correct section of the forums? I would appreciate help. Thanks

 

Be patient. Anyway, the exhaust only gains about 8RWHP, the CAI and headers - no one has them, haven't seen pic(s) and no one knows the gains.

 

You will get about 15-25 Hp at the wheels but thats not really alot to feel with your "buttdyno"...Consider doing an underdrive crank pulley at the same time that will give you about 10hp then you may notice it but if your looking to do 1/4 mile times with all that work you can expect to shave about 2-4 tenths of a second off your average..Seems like alot of work for 2-4 tenths huh???

 

Awesome car, I love the Stillen rear wing also.

 

Can somone give me a description of what the underdrive crank pulley is and what it does? And also a price on this?

 

Do a search on "Unorthodox pulleys", that will answer your question.
