I would definitely stray away from the "Godspeed" turbo kit. I also dare say the turbonetics kit is not genuine.

If a turbo kit is only going to cost you 1-1.3k, I can guarantee unless it's a well used kit it is pieced together with cheap components.

See if you can buy a reputable branded kit from the states and try to get it complete with ecu and loom.

Give it atleast two weeks if you're doing it yourself then extra time to get it towed and tuned.

I would rather pay a workshop 2-3k for install and tune for piece of mind unless I was really mechanically minded
