what hes saying is if you want to make the car quicker get a plog, ( replaces front exhaust manifold) a downpipe ( exhaust pipe that strecthes from rear manifold to cat.) a cone filter ( or any new intake, search on here you can make your own for cheap) hv3 insert ( im a gtp guy, dont ask me lol) and a tune for said mods. doing this will make the car quicker. but if you want to build a "fast" gp you should look to replace your transmission as the 97s had weak trannies

you may want to look into headers rather than the dp/plog as they are cheaper and better ( idk about on a N/A vehicle, do some searching)
