This 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. The LSJ doesn't make very much torque stock, but with this turbo kit it can make over 70 more ft lbs in the midrange, and approximately 30hp to the wheels on most full bolt on LSJs with just the Stage 1 kit.
Turbo: There are two turbo options, the Stage 1 kit uses a K04 turbo (from an LNF/LHU), and the Stage 2 kit uses a ZZP Z54 turbo which is a bolt in larger K04 upgrade. Stage 3 kit uses a ZZP Z57 turbo which is an upgrade again from the Z54. Z57 kits are remote tune only.
Downpipe Options: We offer a stock/2.5" bolt in, or for people that have 3" catbacks, 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.
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. 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.
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:

LSJ Intercooler Pump (most are dead by 60k miles)
These kits are made per order, it can take up to 3-4 weeks to ship.
