a correction
for the BWCR5 box the service manual (and handbook) gives the ratio as 3.16:1 (which i put in the table below), if you actually calculate the ratio using gear teeth ratios it is actually 3.61:1 (which gives the correctly quoted 14:1 overall ratio with a 3.9 diff) - a simple typo that seems to have been perpetuated in a number of sources
so a straight CR5 box will still have a first gear that is too low for you - you will need the 2.92:1 ratio of the sports boxes

Reason: improved phrasing to remove ambiguity
