Thanks heaps! I've actually got a S3 RX 7 thats basically a rolling shell that i bought for the disc rear end. If i was going to use it i also intended to use the front brakes as well, then front and rear would have the 4 x 114.3 stud pattern which is a bit easier to find 14" alloys in. My S3 RX 7 is an auto, but i don't know the ratio yet. If i could find a S2 disc rear and front brakes and struts for reasonably money i'd consider using them instead.

the S3 auto diff is a 3.6 :lolcry:

Hi,

I will back up Felix statment about KE1X ratios.

 

I got more sprinter manuals in mail today and the KE15,17 had 4.22:1 ratio diff. The later KE2X car had 4.1:1 ratio as it advertises the fact in my manuals that the KE2X has higher top speed lower revs yada yada.

 

Also KE1X wagons have 4.44:1 also as Felix said.

 

So Gav if your KE17 is a 4.1:1 is it the original diff still?

You probally right, KE1# sedans both auto and manual are 4:2 and the wagons are 4:4. Mine must be the 4:2 cause its the original item. Also heard that the Tercel diff fits the KE1# housings but not sure about the splines, there're apparently a 3:9 or 3:7 depending on model.

.... The ke16 wagon had a 4.44:1 diff standard.

 

Jeebers. I'll be able to whoop everything all the way to 75kmh hahaha.

 

Keep us posted on that tercel diff Gav, I want to deck my wagon for good open road driving.

Just spoke to a friend who put a Tercel diff into his KE36 wagon which i assume had a 4:4 diff, dropped staight in and bolted perfectly up to the tailshaft. Now when his speedo reads 80kph he's actually doing 100kph. He's wrapped considering his old girl is still a 4 speed. Apparently a KE10 diff would have also fit but the tailshaft bolt pattern was different. :lolcry:

Know you didnt get them but kp61 starlets (the 4k ones) had 3.6 in manuals and 3.4 in autos. 6" u-series

 

According to my instruction book ke17s also had 4.222

 

Do the ke36 axsels fit into the al25 center ? Is this borg or u-series ?

tojo: the it's U series axles that fit, Borg Warner ones are much larger.

I have 3.9's in my ke10 in the standard diff, can't tell you where they came from, they where rapped

up in a plastic bag in a old farm shed. , they are finally shagged and noisey

as after 8 yrs of use. I had the same prob with my turbo K's, most only rev to 6000rpm, and first gear is to

short in the standard box aswell to load boost without a higher diff, especially with 12 inch rims. Was

rubbish with 4.2;s and 4.44's. I am going with 3.7's and 14 inch rims next time.

cheers

darren

yeah, i can't boost in first gear with the 4.33:1. its quicker to take off in second.

that would be horrible, anywhere from 3.9's to 3.5's would be better depending on rim/tyre profile

Looks like the first upgrade going to be 14" wheels with 185/60 x 14 rubber. Also RX 7 S2 front brakes which are nearly 30ml bigger in diameter and are vented. Stage 2 upgrade most likely the S2 dics rear with 3:9 and LSD. If anyone out there can help with any of these bits let me know. :lolcry:

Complete S2 struts i wouldnt pay more than $150 IF the disks/calipers/pads are in good condition.

Complete S2 rear diff with brakes your looking at around $200

An LSD isnt going to be cheap unfortunately around the $1k mark
