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...

    • Will have a look at that. I cant see any leaks 
    • Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.
    • Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.
    • Hi Everyone I am from West Pennant Hills in NSW. Been too busy until recently to attend to my RB25DET Series 2 engine until recently. I am planning to stick it into the S15 shell at this stage, unless a nice SR20DET turns up... For now, i am going to try and get the RB25 running and working well then decide what gearbox to use. My preference is to retain the SR20DET  6 speed gearbox and tail shaft to retain as much and least modifications as i can avoid. I am an old guy and won't be doing any heavy drifting so i don't need a bullet proof gearbox Does anyone have experience with starting the RB on a stand? I got everything setup as much as I can with the info i can find... endless searching and videos on Youtube I would be great to get some pointers Cheers Songo
    • Hey all, Recently have had my s1 r33 gtr serviced and noticed my coolant reservoir was topped up to the max line. Took the car out for 1 yesterday and noticed today the reservoir is completely empty.  Any ideas? Radiator is full
