After doing much research, this is what I have found that will work well for those of you bolting a T25 or T28 setup to your originally naturally aspirated SR20DE.
Starting at the block where the stock oil pressure sending unit for the dash idiot light is:
1. http://www.nissport.com/catalog/prod...EquipmentType=
This goes in place of the oil pressure sending unit into the block. The stock sender fits in the female end of this piece (not seen because it is sitting on that end), and there are three 1/8" NPT female ports used to connect your feed line and other items, such as an oil pressure gauge sending unit or oil temp sending unit.
$49.00
2. http://www.sr20forum.com/showthread....threadid=35577
.060" oil restrictor. This is to ensure the proper amount of oil is getting to your T25. Unrestricted oil flow will blow through the turbo oil seals and coat the insides of your intercooler pipes. It has 1/8" NPT threads will fit into the nissport adapter.
$15.00
3. http://www.anplumbing.com : -3 steel NPT male (P/N 961603)
This is to fit the straight end of the braided line into the oil restrictor.
$1.24
4. http://www.anplumbing.com : -3 steel braided 44” brakeline (P/N 63011744)
This is the line itself. It has -3AN female ends on it. One end is straight, the other is a curved 90 degree piece.
$26.08
5. http://www.anplumbing.com : -3AN to 7/16-20 brake adapter (P/N 591932)
This is to fit the 90 degree angle end of the above braided line into your T25.
$7.31
TOTAL COST: $98.63
