Need quick replies please, i'll be doing this today!

I am putting some aftermarket gauges into my car:

Water temp, Oil pressure & Oil temp.

I already know that i can't remove the factory water temp sender near the thermostat housing, as this reports back to the ECU the engine temp. I've already had a friend fabricate an alloy "T" pipe to splice into the top radiator hose, with a fitting welded onto it to take the water temp sender. That's sorted...

But...

Would i be interfering with the ECU or car in any way by removing the stock oil pressure sender (just below the inlet plenum & AAC valve) and stock oil temp sender (behind the oil filter and close to the block) and fitting the senders that were supplied with the gauges?

I was feeling pretty confident that it was ok, before i had a closer look at noticed alot more wiring than i thought there'd be coming from these senders in the wiring loom...

Thanks for the quick replies in advance.

Hmm, 31 views, no replies, thanks guys! :D

At least you can learn from my experiences here:

Well, i've fitted the oil pressure gauge with no problems at all, works well. Much better than the original gauge that has all sorts of problems reading accurately.

Only problem i did come across was that the OE Nissan oil temperature sender is a VERY obscure thread size. A very rare M12x1.25 thread. Realising that a 1/8"NPT threaded sender won't fit, i went to my local Enzed and had no luck with getting an adaptor. Same story at Pirtek, they said only M12x1.5 thread is the most common and doesn't even come close..

Plan B, decided to test the original Nissan sender against the sender supplied with the gauge. This involved getting out my multimeter, digital thermometer and tested the resistance of both senders at different temps in a saucepan of water on the stove!! :bahaha:

No good there, the senders both having completely different ohm ranges.

Plan C, tried looking through VDO's catalogue for an appropriate sender. Turns out that their only sender in the thread that i was after also had the wrong ohms range.

Looks like the oil temperature gauge stays off for the time being until i can figure out a way to get an adaptor fabricated or find a suitable means of fitting this gauge.

Any suggestions?

I hate to bring back my own thread again, but, don't you hate it when you spend the time, money and effort in engineering a one-off part to do something (in this case an adaptor for a water temp sender) and you could have bought something like this:

But my reason for this post, was whether anyone has seen this oil filter sandwich adaptor for sale anywhere here in Australia? It would help me alot if i could get ahold of this product to help hook up my oil temperature gauge (as i discussed above):

The following pic, you can just make out that it's the threads i need, M12x1.25 and 1/8"NPT.

It will need to suit the thread of the oil filter to suit an R32 GTR as well.

Thanks.

I ll bring this thread from dead again, for people's future information. Ring Mark from Motorsport Connections in Seven Hills, they can manufacture an adapter for oil/water temp/pressure.

Addr.: 15/4A Foundry Rd, Seven Hills

tel.: 98387272

I haven't had mine done yet (waiting for oil change). I ll post how I wen when they are done.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
