npt is predominantly american. it would be bspt.

Yep, British Standard Pipe, weird huh?

Fitted a new oil pressure gauge to my car the other day, had to get a NPT-->BSP adapter, as the NPT thread would screw in and seal, but only by 3-4 threads and I didn't trust it, so checked the thread, and BSP it was...

Where did you get the adaptor from?

Any good bearing/hose/hydraulics shop should be able to help you out. Only cost me $5. :thumbsup:

Thanks, rang up enzed and they quoted me 5bux for a steel one. I was thinking of making a Tpeice there and running the oil temp and pressure sensors together but have read some people have had failures in there fittings from vibrations and fatigue so was thinking if not that to run a braided line from there to somewhere where I can secure the Tpeice so it doesnt have much stress on it.

Anyone had any experience with tpeice the sensors?

yes, that's how I've done it on my race car. braided line about 300mm from the standard pressure sender to a t piece mounted under the brake master cylinder. Been running for years without leaks and senders are working fine.

the only trick was...I wasn't happy with remote mounting the temp sender as I wasn't sure I would get an accurate reading without flow past it. My temp sender is mounted on the remote filter adapter plate instead

That's the problem, the adapter I have only brings the sender out from the block about 10mm, a T-piece style one (was hoping to hook up the factory warning light too) would have worked out about 30mm, that's alot of stress one one fitting given heat, movement of the engine, vibration and the weight of the senders waving about. I imagine if you could brace the top to the block somehow, it might help?

If you used the braided line and just suported the Tee somewhere it would be alright but I think Im just going to get my sump bolt modified to have the oil temp sensor in it and run that there and just use the adaptor to put in the new pressure sensor.

lol no chance.....it is under the plenum on a gtr.

just imagine a piece of braided line 300mm long with a 1/8npt (or whatever it is) on on end, and a t piece on the other. cable tied to the brake lines above the chasis rail and under the brake booster next to the firewall.

works well...very reliable in a car that spends plenty of time bashing around

My answer was serious....

 

Modify the spanner if need be. Find the right one and bend it, cut and weld it to the right angle etc.

 

Otherwise you will have to take something off to get to it as you have suggested. Would it be easier to go from underneath?

 

Im pretty sure i removed a knock sensor from underneath once. Wasnt fun but was doable

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
