By no means is it a bolt on operation, and should never be treated as such. There a lot of home work to be done. And quite frankly I have yet to see anyone go through the correct process of making a turbo car. If you car about your car and keep that motor in it....do some more research on turbo charging and how boost effects everything. Theres a lot of math involved with selecting the right turbo. Compressor maps simply don't cut it.
