WARNING!  JMTC does not provide instruction on how to install this product. Only authorized personnel may perform installation, please use the appropriate certified mechanic for installations of these products!

Before installing your new turbocharger always take a few important steps to increase the life of the turbocharger.

  1. Inspect all components for shipping damage, do not install the turbo if you suspect there is damage due to shipping. Inspect all holes and remove all dust plugs. If any you have concerns please contact us via the information below we will be happy to answer any of your questions, concerns, or provide tech support.

  2. Always replace the turbo oil supply line with the turbo.
    1. Due to excess heat round the turbocharger and particulates suspended in the turbo supply oil the oil will harden or “coke” in the turbo and oil supply lines. If the oil supply line is not replaced with the turbocharger the coked oil will break free from the side walls of the oil supply line and damage the turbocharger bearings. Cleaning the oil line will not help and only aggravate and increase the likelihood of the turbo failure due to coked oil breaking free form the sidewall.

  3. Always replace or refurbish the catalytic converters on mini coopers before installing a new turbo.
    1. The Catalytic converter may look clear but if any oil leaked into it some of the holes might be blocked and will cause back pressure. This starts to happen on Mini Coopers at 15k miles! Exhaust back pressure causes premature failure of the turbocharger. Turbochargers are not designed to have pressure on the exhaust side.

  4. Always prime the turbocharger.
    1. No oil on the turbocharger bearings will cause failure of the bearings if they are dry even for a short period of time

  5. Always flush oil after a turbocharger change
    1. Most turbochargers fail catastrophically this means that the metal and other items can end up in your oil. Always flush your oil a minimum of 3 times with new oil after an oil change.


  • To receive the full 1 year warranty the oil supply line must be changed with the turbocharger.

3 We recommend replacing the oil line and catfold with the turbo. Thrust bearing wear is a sign of back pressure in the exhaust due to a clogged catalytic converter. Oil starvation is a sign of a clogged oil line due to heat from the catalytic converter and exhaust. If they are not replaced with the turbocharger the can cause the turbocharger to prematurely fail.

4 Refresh/Refurbishment is recommended every 10,000 miles, upgrades can be done at anytime.
