Hey everyone. i just obtained a 99 "GTP" today. Here is the add:

01 Grand Prix GTP

Copy and pasted in case the add gets deleted:

For sale or trade is my 01 GTP. It has ported and polished heads with 1.9 YT rockers, LS6 springs and retainers, Crow push rods. It also has full dynomax catback exhaust. Pillar pod with boost, afr, and oil pressure. Car has 126k on it. Brand new tires. New brakes. 180* Tstat. ZZP 1.0 Tune. AC works but needs a recharge. Not as cold anymore.

I had an iffy feeling that the car wasnt a "real" gtp when i looked at it but I went ahead anyway. Using a vin decoder I found that this car came with an l36 engine (non supercharged?) leading me to believe I have a top swapped gt. Which is fine, but I would like to know what im getting into. My concerns:

-Assuming this is a top swapped car what should I look for to ensure this car was modded safely?
-Is there any readily easy way to tell if it was top swapped?
-The security light is blinking (said it was due to the tune)

I will grab some pics tonight. The car is on a stock pulley,doesnt have any typical gtp options (leather, DIC, HUD, or performance shift. The guy said he brought the car to michigan to have zzperformance tune it.





Let me know if there is anything anyone wants a pic of specifically. Thank you in advance.
