You would need a tuner the ATI damper pulley belt and bolt, spark plugs wires, catch can, to add to your existing mods. Custom tune is FREE with purchase of above tuner and parts.

I have talked to a few people but a catch can isn't really needed nor plug wires.. I mean I'm just looking to add a pulley and maybe some injectors. I mean I get you are trying to sell parts but I'd like to see some other opinions from members and not just someone just trying to sell parts.

You are talking to the wrong people.

No I am not trying to sell parts I am offering FREE advice on what will work best for your car and offering you an option where you don't have to purchase injectors.

If you choose to head Professional advice and decide JRE is where you want to spend your money, We appreciate it very much!

I Owned a 2013 ZL-1 for 6 years, and did extensive testing, dyno, drag strip, and road coarse.

Based on what it sounds like you're looking for (a little more power through a pulley change), here's what I'd do if it was my car:

1) Buy a lower pulley instead of the upper. If you do get an upper, I'd only buy a ZPE/Griptec 2.55 upper, due to the design features to try to stave-off belt slip. That said, it is more invasive to install an upper since you must remove the snout and use a press. The larger lower pulley installs more easily in my opinion and you get more belt wrap that way. I'd personally always go lower pulley first, then upper if/when you get to the point that you've maxed out the lower. That's what I've done with my car. I will want a little more pulley with my next round of mods, which will force me to replace the upper, because I'm maxed out on the bottom.

I'd suggest an 8.66" pulley if you don't want to do injectors, but you can run a 9.17", 9.55", or 10" on 93 octane if you are okay with buying headers, injectors, a boost-a-pump, cooler spark plugs, and some cooling mods. If you're going to stop modding here for a while, I'd stick with an 8.66". If you think you want more in the future, I'd probably pick up the 9.17", injectors, BAP, headers, and cooler spark plugs this time around.

2) I personally think a catch can is a good idea. Necessary? ...No Advisable? ...Absolutely.

3) I don't think a thermostat is necessary. Change the fans in the tune and it will run cooler than stock and remain in a tight window of temps.

4) Spark plug wires are like the catch can. Not exactly necessary to make the car run, but they are advisable.

If you think you will just do a pulley and be done with it, then pick up the 8.66" lower, get it installed and calibrated, and rock-and-roll! Personally, I'd get a catch can also, but that's just me. If you decide to go farther in the future, then you certainly can.

Dumb question I know but I believe it's around here somewhere but what is the belt size if I went with a 8.66?

Found it nevermind!

To add to Rob’s list I would definitely get from Ted the Metco with quick release once you change either pulley.

If you can put a pulley on the upper snout, adding bigger injectors will be the easy part.

Thank you but we always try and get our blower rpm from the lower which we found to be best and most reliable.
