My friend and I installed a turbo back in about three hours. The hardest part was the one bolt on the bottom side of the downpipe. On the other hand the uppipe was a little too much for us at the time. We wrestled with it for three hours before giving up for the day. It is now riding around town in the trunk. The heat shroud was making it impossible to get the sensor out, I know there is a way, I just havn't figured it out yet and too lazy to search for the instructions......
