RPM limits have been pushed to over 10,000 rpm with this engine, available with steel or aluminium rods.The REAL deal! Proven time and time again our 2.0LR, 2.0,2.2L,2.3,2.4L engines are the benchmark when it comes to reliable high HP 4G’s.2.3,2.4 and 2.6L Recommended <600whp due to added harmonics for long stroke.You will need a good engine core to be built/swap.

This engine build uses our existing knowledge to build you the best engine possible. This however can be affected when put into the wrong hands.
In all cases, the engine should be installed by a reputable performance workshop and dyno tested or tuned immediately to ensure there have been no mistakes during install or potential issues with boost control, vacuum hoses, breather system or fuel system which could have caused a lean out or blowing out of seals/dipstick causing a fire.
Precision Racing assumes and accepts no liability that your set-up has the appropriate supporting modifications to suit your application. Including but not limited to the following:

• Adequate breather/crank case ventilation system
• Adequate exhaust system and turbine housing size to prevent excess exhaust back pressure which can cause head gasket failure.
• New or cleaned/checked parts within oiling system (oil cooler/lines/turbo/oil feed and drain lines etc)
• If replacing a blown engine- thought must be carried out to ensure there is not an existing problem which will now place your new engine with the same result. (oiling system/back pressure etc)
