there is a supercharger kit for $4500 by VF engineering that will get the car into the lower 13's, if not high 12's. There is also a turbo kit by EIP that will get it into the low 12's, high 11's but costs almost $7000. The famous turbo kit for this car is made by HPA and costs over $20000, but brings the car way into the low 11's with a 0-60mph in the very low 3's.
ive been seeing some people with just a free mod(open exhaust valve) running 13.8-14.0! those are great numbers and i think with a few more minor mods, chip intake exhaust, the car is good for mid 13's.
