There's tons of options, but PD blowers IMO add up to annoying traction problems on the street. Don't get me wrong, instant torque is fun... but spinning isn't winning. And whether it's on the street or the track it's just much harder to get PD cars to hook which ruled them out as an option for me.
Are you manual or auto?
If you're a manual car that's never going to build the block, get a vortech.
If there's a chance you'll build the motor and not go way overboard get a paxton.
If there's a chance you'll ever just go nuts with a insane motor build and push limits get a CPR or JPC single turbo kit to grow in to.
These kits are viable for all options because well... turbos are awesome. Even if you don't want to build the block, you could easily still grab one of these turbos and keep it at stock block level. The reason I mentioned vortech/paxton before turbos is cost. The vortech/paxtons can do just as well at those power levels as the turbo and for substantially less. Don't quote me on this but I think the entry kit to both vortech and paxton is around $4200 without fuel/tune.
If you're an auto car go CPR or JPC single. Nothing beats an auto with a turbo. There's also twin kits out there, but there's really nothing a twin can do that a single can't, and it's just added cost for no reason.
And then on the other hand, don't buy an on3 kit unless you can do light fabrication and don't mind a 40 hour install. Otherwise the on3 kit is actually a very good value with decent components. I would run it if I didn't mind the fabrication. In the end I went with a supercharger because the install was just so much easier.
Also don't buy an EDP kit because apparently the owner doesn't care that people are losing boost after 5k rpm.
I know two people with the EDP single and 2/2 are dropping boost, not to mention the countless other threads on other forums and posts popping up on facebook pages about the issue.
I personally have a paxton and am having a lot of fun with it.
As far as smoking ZL1s I left one with bolt ons by several cars a couple weeks ago on the interstate.
Also beat a 2014 EDP single mustang, have videos of that one.
Also am ahead of a 2013 mustang with a 2.3 whipple. Haven't raced this guy but I know all of these guys, and this guy lost to the ZL1 which I beat.
In the end you really can't go too wrong. They will all be fun and will be way better than no boost, but some kits will obviously be better than others (like CPR vs EDP) and careful planning for your future goals is always the best idea.
