was just wondering how much of a difference do those items make. i bought a crower stage 2 turbo cam and crower valve springs and titanium retainers and was wondering how much of a difference this willall make on my t3 z6. if anyone can give me a idea it will help me decide to keep the stuff or sell it

 

Is it a stock z6? If so, then it means you won't have to tax your turbo to make the limit the motor can handle...somewhere around the 200hp mark. Otherwise, you can turn the boost up and reach the same power without them. :P

 

yes its stock z6 with a y8 block...what do you mean tax my turbo
