Our ZZPerformance entry level turbo swap kit is the easiest way to convert your supercharged LSJ to turbocharged. This will replace the supercharger with an adapter plate, and your exhaust manifold/header and downpipe with a turbo manifold/turbo/downpipe. The kit comes with everything needed to turbocharge your LSJ. The benefits of this conversion is a ton of power and torque under the curve, as well as the potential for more power in the future. Converting to turbo will completely change the driving dynamics of your LSJ powered car. The LSJ doesn't make much torque on the M62, but with this turbo kit it can make over 70-90 more ft/lbs in the midrange, and approximately 50+ whp with just the Stage 2 kit.
October 2024 product update: We now include our ZZP performance stainless exhaust manifold in the Cobalt SS and Ion Redline versions of this kit. To read more about our manifold and the benefits, click here.
Turbo: There are two turbo options the Stage 2 kit uses a ZZP Z54 turbo, details can be found here. Stage 3 kit uses a ZZP Z57 turbo which is an upgrade again from the Z54, details can be found here. Z57 kits are email remote tune only.
Downpipe Options: We offer a stock/2.5" bolt in, or for people that have a 3" catback exhaust, we have a 3" bolt in exit. All downpipes are 3" in diameter, the size you're choosing at checkout is the exit flange size.
As of May 2024 we now offer our ELTK fully set up for an LSJ swapped into a DF Goblin. Goblin based turbo kits are available only with email remote tuning. Goblin kit includes a different intake and our full turbo back exhaust for the chassis.
ECM Flash: The kit comes with a ECM flash, however we have a few options for how that can be completed. We can ship you an ECM pre-programmed, however we will charge you a refundable core charge, or you can ship us your ECM for us to upload the flash, or finally if you have HPTuners we can email you a file for you to upload yourself and continue to dial the car in via email and data logs (this is our preferred method). If only using the 1.0 ECM flash we recommend staying at 15psi or below, due to fuel system demands. If looking to run more than 15 psi a dyno tune or remote tuning (with HP Tuners) is highly recommended. Core file options are for 93 octane fuel only. Because of the fuel system demands, E85 can only be done via email file or in person.
For all entry level turbo kits we highly recommend a wideband O2 sensor and gauge to monitor air fuel ratio. We recommend the AEM UEGO found here.
NOTE: Although not pictured, kit comes with all necessary/applicable bolts, gaskets, belts, and hoses
NOTE: Ion specific, you must purchase a Cobalt MAF sensor, found here.
Highly recommended upgrades that go along with this kit:
- ZZP Stealth heat exchanger for Cobalt or S3 H/E for Ion.
- ZZP Dual Pass Endplate
- ZZP Option B Kit
-
LSJ Intercooler Pump (most are dead by 60k miles)
These kits are made per order, it can take up to 1-2 weeks to ship.

United StatesI don't recommend the DEKA injectors
Even though the title is negative i still give it 5 stars. The DEKA injectors are in the kit probably to keep an acceptable price tag on the kit but those injectors are so hit or miss. Very inconsistent from my experience (i tried 3 different sets of them). They can probably work with some very hands on, in person tuning. but trying to dial these in seems very difficult. I ended up getting the ID 1050XDS injectors and it finally made the car run perfectly. Other than that the kit is all you need. Some stuff didnt fit exactly for me (Like the rear O2 **** was to far down for my cable to reach. But that might be due to some other work someone else did on my car in the past). Turbo feel amazing on the car, WAYYYY better than the supercharger imo. Z57 Starts spooling around 3k RMP and max boost right about 4K. Running 18psi right now, might be turning it up a little more soon. Feels very strong compared to the supercharger 10 psi i was running. Definitely recommend this kit!

United StatesEntry Level Kit LSJ K04
Simple way to make great power for a reasonable price. I went small and did the stage 1 kit and let me tell you, this car really hurts some feelings… the tuning process is a little tedious but you can’t rush perfection, Tyler never fails to answer a question and is always willing to help and make things right. Great job ZZP, you’ll be seeing me with a purchase for the upgraded Z57 soon. 10/10

United StatesSo far, so good. 2007 Cobalt SS
Easy enough install with the Z57 option. Don't be an idiot like me and try to get the turbo in from the top of the engine, I was in a rush and decided to modify my firewall to install it. I later learned it's meant to be installed from under the car.. Anyway this kit pairs great with the ZZP 3in Stainless exhaust with no resonator and a muffler. Came with everything needed down to tiny little washers, as well as plenty of extra fittings. Great kit to buy to get a big turbo swap and slowly upgrade it. I've gotten 3k miles so far.
