Default VS Racing 7875 - Restrictor Needed?

Like the title says... I'm installing a 7875 turbo on a 5.3. Should I install a restrictor in the oil feed line?

Thanks, Randy

if you use the oil feed kit from VS it's slightly restricted.

just make sure your drain is a nice slope into the pan.

probably skip any sort of HV/HP pump too unless you have a built motor and the builder spec'd it

I’ll be making my own feed/drain lines. I’m in Canada so because the cost of shipping and the exchange rate it’s a lot cheaper to buy that kinda stuff locally. Will probably install a moderate restrictor.

Viren says only use a restrictor if using a high pressure/volume oil pump.

If you are using a HV pump and want your turbo to live, use a restrictor..... they will likely tell you the same should you call them.

Is the stock 5.3L oil pump considered a high pressure/volume pump?

No. You have to buy another pump for HP or HV. Or shim the existing pump for higher pressure.
