I am currently installing a Cartech Street Sleeper kit for the 94/95 cars. I cannot vouch for Cartech's delivery times, as I bought the kit used, but I can say the kit installs very nicely and looks to be good quality. To ease the install, I removed the air pump (I planned to do that anyway). My front passenger side motor mount bolt had to be cut (it was one of those nut/stud deals) to make room for the exhuast bypass, and I had to clip one piece of metal to make it easier to get to one of the intercooler plumbing hose clamps. The intercooler is a tight fit, but it will go in without removing the bumper. Oh yeah, the person I bought the kit from has a custom 3" dunp pipe made (never installed) that needed a small indentation (firewall interference). Other than that, it is a well designed kit.
Also, Cartech has been helpful answering my questions when I have called, and even faxed me install instructions. They were not real clear (black boxes instead of pictures), but they did not have to do that, considering they didn't sell me the kit.
Let me repeat - I did not buy the kit from them, and I encourage you to check whichever turbo company you select thouroughly before you send them any money. I can only critique the quality of the kit.
