Hi
I have a HR31 skyline in which I have put a RB25 DET. I need to know if it is at all possible to put a R33 Dashcluster into my vehicle as I have been told that the HR31 has a cable driven rpm and speedo as well as I would now like a boost guage which the R33 would have.
If anyone can give me any information it would be greatly appreciated
Thanks

Does not fit. Fit an aftermarket boost gauage for around $50 as there is a perfect spot just above your left knee next to the steering column.

There is a electronic speedo output from the stock dash which went into the stock RB30 ECU. Work out which wire it is and splice the RB25 ECU onto this wire.
