Rb25 wiring question...

[Slowrolla97]

I am rounding up all the parts i need for my rb25 swap. I have everything I need but I am unsure about the wiring for the tach and speedo. Will I need an r33 gauge cluster or could I use my ka cluster? I am sorry if this is posted somewhere but I did a quick search in the RB FAQ and didnt find anything.


Also if anyone knows where I can get a set of some Bee*R b5 wheels I want them bad. Have cash in hand for them, just cant find them...

You don't need an R33 cluster, just need to get a secondary tach reading (afc, tt, bc, etc), and just try to match them up as best you can. The stock tach (if dohc) could be adjusted from the variable resistor (small and blue, only blue one back there) from behind after you take apart the cluster. As for the speedometer, I've left mine as it was. Make sure you have a secondary reading for your tach though, otherwise it'll be waaaaay off (trust me). hope that helpss

What he said.

Speedo will work.

Adjust tach with blue screw.

[eh?]

Your profile says you have an 89. S14's have no probelm. I don't believe your tach or speedo will work correctly. The S13 tach can't be adjusted. Wire up the R33 cluster or look up LS automotive, they make tachs and speeds for RB/s13s.
