I have a almost new STS turbo kit that is custom built for the 5.7 Jeep commander will also fit the grand cherokee, also the kit can be made to fit basically any vehicle. This is the stage 3 universal system. The kit was removed for financial issues. It is in perfect shape and just needs to be bolted up. The piping and install was all done professionally by RPM North in NY. Besides the kit I will also include an SCT tuner. The kit and tuner with install cost me $8000. I am selling it for $4500 or best offer. Feel free to ask me if you have any questions. Also can send pics.
Also for sale I have an intercooler that is custom made for the car for $150, Tial 50mm bov $150, Brand new boost gauge and electronic boost controller $230.
