Hi. I am about to purchase a 99 spyder gs-t . I would like to know if anyone can make an estimate at what kind of 0-60 times im lookign at if I get a greddy catback/exhaust,a good set of headers, and a cold air intake. Also, would anyone attempt to run NOS on this engine? What other modifications would you suggest and how much difference will they make? Can anyone explain a good way to convert the estimated horsepower to the estimated 0-60 and quarter mile times with this car? Thanks a lot

 

For one, you can't get a header...the car has a turbo manifold. Are you talking about 0-60 feet times or 0-60mph times?</P>


Also, yeah, you can usenitrous on those engines. They're quite resiliant to detonation, but there's always a breaking point. </P>

 

im talking about 0 to 60 mph . thanks for the reply.. more would be great as i am supposed to buy this car this weekend. thanks
