Gtr gauge issues

[Jezzmode]

Hey guys can't find much in search...

I had my engine rebuilt for my 33gtr, and now my speedo reads exactly 1/2 kph and the revs are all sporadic? I've had someone look at it and came up with nothing. If the engine builder accidentally mixed up my gearbox with a stagea awd could the speed sender be the issue? I don't want to fork out a grand to have the same issue? Or could my cluster just be effed?

This is such a random and bizarre problem that it will be very unlikely that you will get a solution across the internet. Nevertheless, a few points deserve to be addressed.

1. What do you mean "speedo reads exactly 1/2 kph"? Do you mean, that it reads exactly 0.5 km/h, that it reads either 1 or 2 km/h or that it reads exactly half the speed that the car s actually doing?
2. How and why would your engine builder "accidentally mixed up my gearbox with a stagea awd"? Is there more going on here than you have said? Why would an engine builder be swapping gearboxes?
3. What do you mean by "fork out a grand to have the same issue"? Particularly when you present it as a question, with a question mark at the end of the sentence. What are you saying?

With respect to later R33 speedo problems, there was a recent thread with a similar problem. Maybe the solution was posted. Search it up.

"could my cluster just be effed?" Maybe. But if you have problems with 2x electronic meters (ie, they both just receive pulsed signals) then.....would you not suspect a wiring plug related problem.

This is a logic problem. Arrange all the data, then apply logic.

If in doubt, take it to an auto electrician. If an auto eleccy cannot fix this in a couple of hours, I will be horrified at him calling himself an auto electrician.

I don't pretend to know much about cars, I just love em. 

Answers to the following 

1. If I'm doing 60kph it reads on the speedo 30kph

2. There was a stagea awd in the shop at the same time as mine was... I don't know if they're visibly identical and if they are are the speed senders the same? Perhaps they had them sitting next to one another and just mixed them up...shit happens. I never said it was a good engine builder. Engine lasted 300kms shit it's self and then they sold up days later...

3. I don't want to spend $1000 on a new/different cluster, only to find out I've got the same issue

Both the WGNC34 and BCNR33 have the FS5R30A as a transmission option. The Autech 260RS version is going to run the same sensor as a BCNR33. The RB25DET version does have a different speed sensor but the RPM/tach issue is unrelated. On R33s the tachometer comes from the ECU.
