SO I used to have a DD GTP with Plog pulley tune plugs and down pipe. Was great fun for a simple DD. Had it from 10,000 miles to 110.000 miles and finally traded it in. Just bought myself another DD GTP. ITs a 99 with 56,000 miles on it one owner car.

I want it to be a reliable mid to low 13 second car and I was figuring the following would work well. Please keep in mind that it needs to pass CA emisions so any suggestions or tips are welcome. Not worried about visual just tail pipe and OBDII

PLOG with Down Pipe or Headers (cheapy Ebay ones.).
Intercooler (one the fence for SS or full 2.25)
Rockers 1.9's
Pulley 3.4-3.2 (whateer gets me to mid to low 13's)
Tune

Will this get me to my goals.

thanks

Eric
