as i have mentioned in my other forums... i have been reading this website for about 3 months but only started to input my thoughts as of today. i have had my Z for only 3 weeks and already have a injen CAI. i was wondering if i put nismo headers plus borla exhaust... how much total hp and torque i would have at the wheels and at the crank??? i just honestly want to beat the 300hp mark. since most of my little races are in the streets... i want more torque than hp. other than the CAI, headers and exhausts.. what else could i do which will up my torque a "significant" amount??? do u guys think i should maybe install a new plenum by crawford? some people tell me that its not worth it and some people say that with the new plenum and my CAI it will sound wicked. what do u guys think?
thanks.
peace.

 

get the Crawford Z Tuning intake plenum... this alone is a very good mod for more HP and torque. There's a banner ad somewhere for Crawford.

Next I'd say get NISMO cams.

All that added to the other mods you mention and you will be above 300HP at the crank.

It's whats at the wheels that matters

CLS has an Injen intake, Borla exhaust, and a plenum. Just with the intake and exhaust you should see over 300 hp at the crank I would think.
