Ok when you install the "T" fitting into the block where to oil pressure sending unit is, do you also "T" the oil pressure sending unit in to that "T" thats got the oil line going to the turbo? I found 2 pictures that show the pressure sending unit prefectly and one has the "T" plus the another "T" on top of that so that the oil pressure sending unit is connected to that. Then there's another pic where it shows a "T" just screwed into the block where the sending unit was and then one end going to a oil pressure gauge and the other going to the turbo. What is the correct way to go? Or does it not matter? Thanks.

depends if your using an oil pressure gauge or not

if you arent using an oil pressure guage then u can use one T, one into the bSPT female fitting on the block, might need an adapter for that, one for the oil sending unit, and one to your turbo

i suggest u use the tuner toys fiiting, cheaper than the nissport gets the job done,

i second the www.tunertoys.com fitting i bought a complete oil line kit from them came with the oil adapter,feed line,return line and a bunch of fittings and clamps.all for 85$

I bought the tuner toys fitting and used it for almost a year. This is up until about 2 months ago when I noticed an oil leak I found coming from the tuner toys fitting. As I tired to loosen the fitting it broke off. It had cracked and that's where the oil leak was coming from, it was just waiting to break.
I've bought a Nissport fitting since then and it is much higher quality. I'm not saying the tuner toys fitting won't work, but the IMHO the nissport fitting is worth the extra $$.

and if you want to spend even more money ;)

Ok then the size of the hole in the oil sending unit in the block is 1/8"? And so you need a 1/8" male and female fittings, one is a "T" that goes into the block the other is a Female adaptor that goes to the oil pressure sending unit its self and the other goes to the "T" that's in the engine. RIght?

The fitting in the block is 1/8 BSPT.. most fittings for oil pressure gauges are 1/8 NPT. They are different fittings.

All the fittings mentioned in this thread accomodate for this and have BSPT and NPT ports. At a minimum you will need a 1/8 BSPT-> 1/8 NPT fitting. You can tee into that to hook up an oil pressure gauge and a oil feed line (but you'll have to lose the stock sensor).
