I found a picture I took doing my build which may demonstrate how I think you accomplished adding those lines..I am guessing that you do not drill all the way through, but just enough to get into the channel shown in the picture below. Charles, can you confirm that this channel will serve as a suitable oil pressure port?
Thanks.

I spoke to Charles about this already. Relocating the oil pressure sending unit is a bit of a task. Nissan has press-fit a hardened fitting into the end of that gallery when they were performing final machiningg in the pan. The fiting is very hard and not easily drilled out. I have been making slow work with a die grinding. Plus, you have to tap the hole for 1/8" BSP thread, too.

Did you guys check the Manual Pathfinder`s Thermostat ? it comes with only one outlet the small one is disabled ? am not so sure but i`ll check it once i visit the dealer.

rrmedix, I'll answer it for charles. yes that is the same oil gallery that feeds the oilpressure sending unit.

NetShark,

the pans have a second fitting that can be used for adapting external lines. It is above the oil filter location. on non-revups, nissan has a block-off fitting. On rev-ups, there is a sensor in that spot. I think it is used for oil temperature.

actually its hard for me to tell from that picture especially since i did that over 2 years ago now... however, i trace oil passages around with compressed air usually, and just looking at the casting. the turbo oil feeds i did are pretty easy tho, as one of them is the stock oil pressure sensor location and then the one next to it i just tapped into the flat surface next to the stock pressure sensor location because i could tell it would go right into the same pressure channel.... and like quad is saying; the place i located the pressure sensor in the front is where there is normally some sort of ball bearing kind of plug to plug up the end of that channel that the turbo feeds are going into... it was a pain in the *** to get out.

Next time I am in there, I am going to use a 90 degree fitting to turn the pressure sensor... because right now its a little close to the greddy IC pipe for my liking.

Sorry Andrew my bad i mean`t the Water Thermostat, instead of blocking it with the 1/8 NPT Plug you can use the Manual Tranny Pathfinder`s Thermostat.

do you have a part number for that T-Stat?

Thanks Quad & Charles for your response. Thinking about getting a 1/8 BSP tap to accomplish that project. Not 1/8 NPT?

QuadCam

iTrader: (8)

they are kind of hard to find individually, but the 1/8" BSP tap is available in most "metric" tap sets. I haven confirmed that it is available in most craftsman sets and also in Snap-On sets. It is not a metric tap, but that is where they put it.

Charles,

Quick question for you. WHat size oil feed lines did you run to your greddys -3AN or -4AN? Also, what is the thread size for the oil feed side of the turbo. I want to replace the stock banjo fittings and oil feed lines. I plan to use standard An fittings, but I don't know the thread size for the banjo bolt. thanks.

phunk

iTrader: (21)

they are -4 but I cant remember if I put restrictor fittings on the turbo or not, i may have. but i think the greddy turbos have built in restrictors

I am having a ***** of a time trying to get that ball bearing out of the oil passage. I am worried that I may have f'ed the pan for trying to tap that for 1/8" BSP. I have a couple of extra pans, but this one I already had powder coated.

I have been using a taper-bit die grinder to go at that damn bearing. It is very time consuming!!!

Hey Quad,
Any pics of your efforts would be appreciated. I am pretty solid on what you are doing, but any visual aides would help.
Thanks Man. Keep up the good work.

I presume this is the part you are attempting to drill out? (Outlined in yellow)

QuadCam

iTrader: (8)

yup. that is the part. It seesm to be a VERY HARD ball bearing! I flattened a center punch when striking it.

I'll take some pics next time I attack it!

i owned that *****!

I was under my car over the weekend and was looking at the pan. It looks like if you relocate the OIL pressure sesnor to the front of the block, you are going to have to modify or remake the alternator bracket. ON phunk's car, it doesn't matter since he moved the accesories around anyway. On a stock car, the bracket appears to be in the way.

BTW, I got that damn ball bearing out! I had to show it who the BOSS is!!! I'll snap pics shortly.

rrmedicx

iTrader: (54)

I can't wait to hear about your technique for ball bearing removal. It looks like a Beatch!

Besides, with your talent Quad, I'm pretty sure you could fabricate your own custom bracket to work around any fitting you choose on the front end of that channel.

QuadCam

You'll laugh at the picture. The ball bearing has been mangled! It is so hard and so slippery that the die grinder bit kept slipping off of it and I hit the edge of thepan. the bit was chewing up the pan. once I got it out, I had to use a cut off wheel and a different die grinder bit to give the block a nice clean mating surface again around the new pressure port.

I have been thinking about leaving the oil pressure sensor in the stock loaction and just using a T-fitting in the new location to feed the turbos.

Any hammering to push it through? or was it a poking match? LOL

Any concern for damaging what is behind the ball bearing, which could ultimately not leave you with enough material to actually thread???
