Rb25/26 Swap

[Brucelee Lande]

Hi all ,

I am in need of some advise.

I have a '98 Skyline Gtst and I'm swapping to an Rb26.

I have a RB20 gearbox and I have a RB25 gearbox.

Question: Which one should I use?

Anyone that could give me some advise, it would be highly apreciated.

Thanks , Bruce

a quick question, i know RB20DET boxes have a manual type speedo cable. that runs from the side of the box into the back of the dash cluster. do RB25DET boxes have a manual speedo cable too? i was under the impression that they have a digital speedo. if you were to put a Rb25 box into a R32 how could you hook up the manual driven speedo cable cluster with an RB25 box??? any info

he has an R33... so not an issue

but for those with R32's.. what about a VL-turbo box? it has a manual speedo cable and is similar to the rb25 box i believe...

Just drop a GTR sender into the RB25 casing.

Thats what i did being the HR31 speedo is different to the R33 GTS-t.

Just swap the gears on the driver
