My stock bolt on 03 gt is laying down 289 rwhp and around 330ish rwtq. I was thinking of doing a stage 2 na cam and spring upgrade, (currently has stock h/c/I ) what stage heads/port job would you recommend for dd street use and what power increase would you suspect?!
We would suggest the stage 2 and you should see 18-22 RWHP increase - cams and springs will take further advantage of the port job and are also recommended.
