My set up b18c jdm lsd tranny , greedy 48/60 t3 stock internals 2' intercooler plumpbing "2.5 inch exhaust greedy intercooler 255 walbro fuel pump with dsm bluetop injectors My question is this I was purchasing oil lines from stealth mode performan when i noticed a wirewall kit so I bought it however there was an oil restrictor kit what is it for and do I need one for my set up?

 

sometimes when u put a turbo on your car and hook up the oil lines(depending on what size u use) you can send to much oil to the turbo. which will go past the seals and into the exhaust housing of the turbo. resulting in smoke. that is why u need an oil rest. to cut down on the pressure and amount of oil u get. i think turbos only need like 30 psi of oil. the time i noticed oil in my exhaust was when i would set still with the car ideling.
