Easy solution to your problem. Just let me know how much extra HP you want. I would stay with mayb 100hp extra as the maximum any more then that and you asking for it.
Buy a nitrous kit from NX and install it. They come with 35-50-75hp jets. I have had nitrous kits on my last 3 cars and they make a butt load of power. It will wipe the smile off a s/c boxster's face quite easily and he will have no idea what it was you did. He will notice your nice clear tail lights however lol..
I understand this isn't viable for most of you guys, I just threw it out there for a laugh. I really have had nitrous on 3 of my old cars and I'll tell you in my GTi with 150hp shot direct port it would mop the floor with a Corvette easily and my Talon (which doens't need it, 425 without nitrous) was nuts with a 50hp shot on race gas.
