Differences Between Rb20 & 25 Gearbox's

[mr_rbman]

Just wondering apart from the physical size if there were any markings or differences between the 20 and 25 gearbox?

Just need something to confirm that the gearbox i'm look at is a series 1 rb25 gearbox!

Cheers

its hard to tell the differences between them when the 20 box is in the car but from what i can see the whole speedo system appears to be different? The 33 one looks as though it just slides in there but the 32 one looks as though it screws into the gearbox?

the easiest way to tell if its a 25 box is to pick it up... they are fat and heavy things! rb20 boxes are light as by comparison. both speedo's slot into the hole and are held by a single retainer, but the RB25 box is electric and the rb20 box is cable driven, hence the screw on attachment.

ye, problem is the only 20 box i have access to is in my car, 99% sure this is an rb25 box just looking at the speedo drive area! Hard to tell just by looking at it the size differnces!

seriously. the 20 boxes are long and skinny where the 25 boxes are acctually shorter but MUCH fatter around the mid section

well the 25 box needs 2 people to lift so i'm guessing the 20 box you could lift with one person?

[Simon-S14]

yup i can lift them pretty easy, a 25 box i cannot lol

I can lift the rb25 box myself, and im hardly a strong person.
