Finally got my HX40 couple questions before install

[bNasty]

Alright guys I have spent hours and hours reading through the holset threads and maybe I missed something but I have a couple questions. As I stated above I finally got my hx40 and i'm pretty excited to install it but since my last turbo (g60) failed due to improper oiling I want to get it correct on my holset. Obviously before I mount the turbo I plan on checking the oil pressure at the oil filter housing; where I plan on feeding the turbo. My setup is a 2.3 stroker and balance shafts removed. I have a FP oil restrictor/filtrer combo with the .030" orifice. Does anyone thing that this is a good idea to run with the holset or will it restrict the turbo too much? Ive read that you can drill it out with a 5/64 bit but I just wanted to get ya'lls opinion on what I should do. I plan on draining the holset with a -10an ss return which I already have.

My second question is the turbo came with this fitting already on it. Im not sure if its a restrictor or just a regular fitting it looks smaller than the regular -4 I have on my g60 but im unsure.

The bottom pic is the fitting on the g60 and the top pic is the fitting on the Holset

If you run a journal bearing turbo with a .030" ball bearing restrictor, it will blow the first time you make boost.

Get an idea of what your pressure will be, and drill the restrictor accordingly.

Right thats what I plan on doing. What are your thoughts on the fitting on the turbo itself?

Looks good- appears to have around a .100-.110" orifice already. May not need a restrictor at all.
