All I seen about the stock turbo online is this: Stock RPM. 210,000 RPM yes 210,000 but capable of 230,000 RPM. boost 18-22psi Made by Garret ( not 100% sure though on builder). Todd when I find the link I will post
the U.S., the compression ratio is 9.8:1; the engine can run on regular but premium is preferred. The engine takes four quarts of oil, synthetic 5W-40 recommended, with oil change intervals are set at 8,000 miles. Coil-on-plug ignition fires dual-tip spark plugs. Fuel injectors spray at the intake valves. The turbocharger spins up to 230,000 rpm [verified by engineer David M. Schmidt], forcing extra air into the cylinders; it normally runs at 210,000 rpm. The system uses two charge air coolers (commonly referred to as intercoolers) behind the driver- and passenger-side air inlets; these reduce the heat of the high-pressure air, allowing for higher air density and reducing the potential for engine knock. Observers say boost peaks at a whopping 18 psi, far higher than past Chrysler limits.
