Question:
Hey well my boss has a 2002 viper and i have a 98 gt 5 speed.. what do i need to do to my car to be able to run with him and try to keep up.. he hates me and i want to beat him if i ever see him on the road.. give me a plan on what i need to do thanks....

Answer 1:
Tie the vipers back end to a tree.  I mean holey moley, any mustang (with the exception of the 03 Cobra) will need VERY serious mods to even come remotely close. Buy the viper, gimme a ride in it.

Answer 2:
Quickest and most painless way would be to just sell your car, and buy a faster Viper.

Answer 3:
Do the head swap, bolt ons, gears and a 100 shot of the wet stuff.

You can have a Bad ass MK4 supra with a T88...   one of the locals in cola town    smoked a new viper R/10  ..   it was Tiiiiight!  hehehe...

buy a viper and take that engine out and put it in yuour car and then put a twin turbo and u will smoke em ...

or take an RX7 body and put a mean 4 cyl in...wait...that wont be fast

But you could use a rocket launcher...There isnt anything about rocket use in the SC codes and regulations
