I've heard that on a honda when you turbo it that it is wise to put some kind of oil resrictor in the oil feed line to reduce the pressure, because the engine oil pressure is to high and will blow the seals in the turbo. I don't know its just something i heard and wanted a second opinion on

 

this is what i have been told,

-3 fine without
-4 needs a restrictor

in my exp, my old to4b never leaked w/o a restrictor and -3 line.
my t3t67ho did with -3 line, but i have been told lotsa people have had leakage issues with that turbo.

 

This how we did a restrictor on a buddy's car. We install a shut off valve that is about 1/3 open then install a gauge after it . We can adjust the pressure until it's below 40psi at full throttle.




After your happy remove the **** so no one will screw with it.

 

damn thats a neat idea you got there

 

If that's a 1/4" copper oil feed then it's bound to leak in the future. Rigid connections + compression fittings + vibration = mass oil leaks.... trust me i've been down that path a few times until I upgraded to ss braided throughout
