Rb20 4wd gearbox helo. I'm actually new to the RB series engines.. But I have a little knowledge.... Just a little...haha.... Anyways.. Just wondering, is the 4WD Gearbox out of a RB20 same and strong as the RB25 and RB26 4wd,'s..??? how about the ratios...?? I couldn't find a Rwd Rb25 box here in Malaysia... So this guy offered me a 4wd box... But he's not sure what engine is out from.... I've seen some Rb20 4wd Boxes.... Just confirming that the box is as strong for high HP.... And I. Putting up together a 25/30 with the stock 25 internals in the RB30...its gonna get into a Datsun KPB310 ...Datsun 140Y... Anyone?
