i agree.. a mod even messaged me on the power i could easily get with a gt without a top swap..Originally Posted by CTKGP09
"If you have emissions testing...I would go with the PLOG and a 3" Catted Downpipe from ZZPerformance instead...it'd be pretty close either way...but the headers flow better at the top of the rev range.
To add, I'd get in contact with Will @ Overkill for a tuned PCM. I'd also do a set of AL606 plugs gapped at .050", a set of MSD or PRJ Plug Wires, get a 180* T-Stat, yank off the throttle body and clean it...and toss a cone filter on the end of the MAF sensor...you can get a big 9" cone from your local autoparts store...or online.
If you want more than that...then I'd spring for the HV3...after that, if you're still looking for more...depending on your mechanic level or if you know someone...I'd then say...if your level of working on a car isn't that great...get a set of ZZP ER Rockers...I'd however spring for the ZZP GT2 cam, or one of the Abbott Racing N/A grinds...they are both stout cams. At that point you'd be making about 210-230 FWHP, which is around a small bolt-ons GTP or so. You would need stronger valve springs...and a new timing chain/dampner when you toss the cam in. I'd recommend Crow 105 springs...and then a re-tune probably with a Wideband and have Will do an in-car tune. "
