ok thanks guys. what are common speed mods you do to the GPs? and approx how much $ would it take to make it like 11-13 secs? im looking to make it nice and zippy when i would get it. a friend told me with $5000 or less you could do it.
To get in the 13'*, its easy.
CAI, 3.4 or 3.25 pulley, headers or PEM'*, DP, PCM, and rockers will take you way deep in the 13'*.
The GTP will respond a just a slight bit better to mods than the Bonnies because of weight differences.

8mm wires, MSD coil packs, you can also pick up a reprogrammed PCM for a couple hundred. Check out http://www.pfyc.com and http://www.3800performance.com

They didn't have 3400'*. They had the 3.4L DOHC. It was fairly quick, but the engine had some problems.
