The info is on sxoc.

The S14 box is an option to consider as well

s13eater · #14 14-01-2007, 01:28

we need the info on hear, not to go searching the sxoc.

s13eater · #15 14-01-2007, 01:29

and why does it say sxoc, i thought it came up as a swear word lol.

xoc was in the filter for a while, not sxoc or zxoc. We had a lot of problems with spam posts with that url title Shaun.

Ive been trying to find it on sxoc and havnt found anything as yet.

From what magnum says the mk1 and mk2 boxs have different ratios. Is this definatly right. I wasnt expecting that. i just want to compare the s13 ones to the s12 ones

Just look at the S13/14 downloadable manuals for the data.

mk2 s12 and s13 are identical box ratios (in the uk anyway). S14 box can be used to replace any car using an s13 box if the S13 CA style belhousing is used rather than the s14 SR type. Straight swap, 20 mins for the bell housings.
As Martin said, s13/14 ratios are on the downloads, but essentially the s14 box gives longer 1st and 2nd, almost the same 3rd, identical 4th (1:1) and slightly shorter 5th. Its essemtially a 'close' ratio version of the S12 mk2/s13 boxes. There are afew variants of each of the boxes. I have had 2 different s12 mk2 boxes, 3 different s13 boxes and 2 different s14 boxes, but they are detail changes and only some parts are interchangable.
Ultimate box design is the last s14 boxes which have a 'trapdoor' design (similar to winged anti surge engine sump pans) on the centre steel bearing carrier that stops oil starvation to the bearings and gears on hard accelertaion and G loads.

I found a excel that mention 200 SX se 1987, the 5Th ratio is different that on mk2 ratios said before:

1st 3.321
2nd 1.902
3rd 1.308
4th 1.000
5th 0.838 instead of 5th 0.759:1

Final gear ratio 4.111

Perhaps it's an american difference.

What do you think about it?

The final ratio is in the rear diff. Changing this would have the best effect.

Manual - 3.7
Auto - 3.9
FJ20 - 4.11
