Did you mean $700 for the car or just the turbo? If it's just for the turbo that is waaaayyyyyy too expensive! I think that those cars have either the 14b or the T25.... I cant remember. Those turbos are small yet capable of pushing around 14 psi max. Anyway, if you just want the turbo, you can get the same turbo and reconditioned for about $200 at
www.cheapturbos.com or from the junkyard for about $75 if you pull it out yourself. I would get a T3 if I was you........
