Greddy has only one stage which means the huge turbos will spool much slower and if your not building your motor for big power then youve just installed a laggy a$$ setup for nothing. Smaller turbos less lag. They say greddys fitment to the z is much better but its not worth me paying 8500 for a greddy tuner kit or 8000 for gtm ready to go kit. All in all Supercharger or turbo youll be happy with either man. Iv had both and I smiled everytime I got in them.
