You can run NOS pretty inexpensively. However, it is important not to go overboard with the stuff. It is too easy to keep adding NOS and going faster but there is a limit to what the motor and drivetrain will take. The more often you use it the less you will be able to use. Ballpark figure for very occasional use would be a 75HP kit. Bone stock a M103 (3.0, 2 valve per cyl 177HP/188lb-ft) 300E (inception to 92 model year) should be able to do 0-60 in the 8.0-8.5 second range. If a taurus smoked that they were an SHO model. Still, think of it this way...Mustangs and their ilk attract cops, your car attracts women. j/k (sort of)

Hope this helps...Lee
