Rb20 Box Compatibility With Rb25

[humz]

hi peeps just a quick question,

does the rb20 manual box fit the rb25 engine??

why you may ask.. coz theyre cheap. its only a s13 silvia.

how weak are they compared with the 25 box?

differances, gear ratios ectt???

[Adriano]

They bolt on, and they are heaps weaker, but still quite strong

agreed. You don't really need to consider the 25 box until you are well over 200rwkw imho.

I have a rb25 in my r32 with a rb20 box and no problems bean going hard for

2.5 years now box is like day one and I would say my car has 180 rwkw and it is heaver than a s13 and yes direct swap.
