Nissan 200SX Club - South Africa

Hey guys. This is for the tecki guys out ther. We just broke a shaft inside a SR20box, so we switched the RB20 box 's bell housing from the damaged sr20 and put that in.surprisingly the overall length of the srbox is longer than the rbbox,s the prop had to be lengthend.So far the backie seems to be running better with the RB Box.Now my question s
1: wat are the difference in gear ratios between the 2 boxes
2 :has any one out there done this
3: how much more abuse can the rb take in comparison to the sr box( it gets hellova lot of abuse)
4 : now that the sr box is repaired how will this be for a rb20det motor track only?

as far as i know the SR20 and RB20 box and basically the same. now i can be very wrong with this as well

Also think the SR and RB20 box is about the same. RB25DET has a big strong box. Big differance.

why do you say is it running better?
so the Rb box with the Sr bell housing is shorter than the stock Sr box?

yes the rb box with sr bell housing is surprisingly shorter.
i know the rb25 fat box is way different to the thin rb 20box
the backie is running stronger( wel feelsstronger) and pulls loads better, thatswhy i wanted to know is there a difference in gearing.
AND does any one have a rb25 Bell housing for me??!?!?
