R33 what ?,  as that looks like a GTR one. That is not the part number on it by the way.

Why, are you sure it's faulty? What is it not doing - like can't get 0.5v at throttle closed or not deflecting to 4v + at full throttle ?

Anyway I have a GTR one here if required.

Thanks very much for the reply

 

its off a r33 gtst rb3026

Drove the car yesterday and it won’t rev past 3k.. on the laptop the tps gauge is not moving at all. Spoke to engine builder he logged on and had a look and said something about 0.01v and it’s not changing or something while driving or anything

So just to clarify are you saying that the number is wrong on the back of that sensor in the photo?

or that number isn’t a part number it’s just a random number for something else?

Does your tps look similar? Same rotation etc?

again thanks for the info really appreciate it

Yeah that's a random internal Nissan number, not a part number. So yeah that TPS is a GTR 32 -34 RB26 one as I have, as it has the two little locking locators for the throttle closed switch locking wire clip.

If it's at 0.01v constantly yeah that's bad, as it is supposed to be at around 0.5v at 0% throttle and linearly rises to about 4v at 100% throttle as it is a 0 - 5v signal. This is all testable with the engine off changing the state of the throttle position.

Continuity of the 3 signal wires which has the 5v +, 0v and signal v from ECU to the 3 pin should be checked first - you may have a break in your tps cable.

yeah that makes sense, thanks very much.

The mechanic made me turn the car off and then put the foot flat and nothing changed still at 0.01v

Has a new loom in it. New wires to tps etc see photo. It run sweet on dyno and test drive afterwards. I went to go for first drive yesterday, warmed it up around town then went to give it a bit of a squirt and yeah wouldn’t let me go anything over 3k revs

As for the rotation is yours the same in the picture? is so I’ll be keen to buy if your keen to sell.

Sorry didn't read the above ^

Correct, RB26 is clockwise.

Yes same, it's an RB26 one.

Nope. Physically externally the same but with a counter clockwise instead of clockwise rotation.

Automatic ADM R31 / VL RB30 TPS.

I think I now need glasses...

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      R33 GTR running -9 with no tune

      By Murray_Calavera · Posted

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      R33 GTR running -9 with no tune

      By Duncan · Posted

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
