Actually for a decent shop to do the clutch install using a real OEM clutch it probably will cost around 800 unless you know someone.
And im talking about a GOOD clutch job. Not some half assed job where the pedal is vauge and the engage point is all the way at the top. If you don't go after market (which I would seriously look at depending on your goals if you have any for your car) a OEM clutch costs around 250-300 bucks. So watch out for cheap shops because the parts they use SUCK
