Product Description


    NOW FITS ION REDLINE! The Redline kit includes all the necessary parts to fit onto an Ion Redline, it also works with the stock MAF sensor! 

    The LSJ turbo kit includes a 3” downpipe without a catalytic converter.  This downpipe is recommended for off-road use.  If your vehicle will be driven on the street where it is subject to emission laws, please choose the spun metal cat option.

    The LSJ turbo kit comes standard with an external dump wastegate tube.  This setup will be loud at full boost.  There is an option to have the wastegate dump return into the downpipe for a more quiet operation. 

    In deciding which turbo to use, you need to determine how much HP you want to make and how you are going to drive the car.

    Smaller turbos spool at lower rpms but are limited in HP potential. 

    ZZPerformance has worked extensively with turbos on the Ecotec platform and after testing many turbos from Borg Warner, Bullseye, Garrett, and Precision; we concluded that nothing spooled as quickly, made as much power, or lasted as long as the turbos custom developed for ZZP by Bullseye Turbo Systems. We use their extended tip compressor wheels exclusively as these made more power and spooled quicker than their standard turbos. We get many requests to use customer’s turbos but we strongly recommend against this route. If you search the forums there is literally no one making big power with successful builds that run well other than people using ZZP setups. This includes our choice of turbos.

    The 256ET turbo reaches full boost around 3700 RPM LSJ. It reaches maximum efficiency between 20 and 25 PSI on the 2.0 but is normally run a 16-18 psi on pump gas depending on the other mods you have. (We recommend 16psi for 91 octane, 18 for 93) It will make 325-375 WHP but is capable of up to 450 with additional mods to the vehicle and E85. The LSJ block, rods and pistons are not reliable above the 420WHP mark so it’s best to address the engine if you plan on making more than that.

    The 259ET turbo reaches full boost around 4100 RPM on the LSJ. It reaches maximum efficiency between 20 and 30 PSI on the 2.0. To run that much boost, high octane fuel is required. E85 works well and builds using E85 can expect 450WHP as a baseline. More can be had with additional mods. On pump gas 18 psi will make close to 400WHP but it’s a waste of the turbo’s ability and a 256ET is a better pump gas choice. The LSJ block, rods and pistons are not reliable above the 420WHP mark so it’s best to address the engine if you plan on making more than that.

    We have done custom builds with turbos larger than the 259. They require E85 or E98 or C16 to take advantage of the boost levels. Firewall modification, custom 3.5” downpipe, 2000cc injectors, dual in tank pumps. The turbo won’t spool until ~4500 rpm making it a race only or dyno queen setup. Drivability is poor. A boost referenced fuel system is a good idea on high HP builds.

    The LSJ turbo kit will make approximately 10psi without the boost control option. Adding our manual boost controller will allow you to increase the boost pressure from the base setting. BRFPS required at boost pressures over 17psi.

    Fuel injector options allow you to add 60lb or 80lb injectors to your turbo kit. *We recommend our BRFPS when running 80lb injectors this eliminates the idle surge issues associated with large injectors and high factory fuel pressures.

    Tuning options include no ECM file, standard ECM file for setups up to 375whp(customer provides ECM core), or standard file with core included.

    On our LSJ turbo swap kit, you need to keep your MAP sensor- the one mounted on the intake manifold, as well as the barometric sensor that sits out in the open.  You don't need the blower inlet pressure sensor for a turbo setup.  We simply delete that code on turbo swap ECM files.

    ZZP bov comes in two colors black or silver. Please specify color at checkout or we will choose the color for you.

    Tial bov only available in silver.

    To keep costs down some of the items in the turbo kit that are included MAY be used such as the oil dip stick & tube, intake manifold, alternator, and throttle body.
