Hey zook drivers.

Starting to really get over the gutlessness of my vitara, having no way of attempting highway hills with dropping back to third gear and in some case 60-70kmh, and before you chime in with its not a rocket ship. I don't expect it to be.
But It would be nice to not be passed by Volkswagen beetles and have to rev the tits off it everywhere to get it moving.
From reading the diff ratio application thread I believe my car being a 1993 4 door lwb vitara JLX estate I should have 5.12 diffs. And I currently have rebuilt the entire driveline front and rear diffs, engine, gearbox, transfer and the oldest of those being 10000km old.
It's running a 2 inch lift and 2 inch body lift with 31 inch tyres. It sits at about 3500rpm at 100 Kay's an hour on the highway. And the speedo says 90 when I'm doing 100kmh

Does your VIT feel the same and drive the same?
If you guys could comment your tyre sizes and diff ratios and speedo calibration accuracy, so i can have a rough idea if my car is behaving what is considered normal for these mods?

My lwb 93 reads 115K at 100 on the gps.
Mines an auto, with 2 inch lift and 2 inch body lift, with 30 inch tyres.
It pulls the camper fine, though would be better on stock tyres, off course.

I suspect an engine power issue, or excess weight.
Or somebody in the past fitted higher ratio diffs.
If it is a gearing problem, then your only option is importing 5:7 diff ratios from Europe.
Or downing tyre size.
Mine are 5:12 diffs, that should be what is in yours..
Autos do compensate a fair bit for larger tyres.

Looking at a gearing calculator

I personally think the auto isn't changing into overdrive
The rpm vs speed, 3450 is spot on for being in 3rd, with true 31" tyres, (3500 rpm with 30.5" tyres)

Approx 2518-2560 rpm will be 100km/h in overdrive.

Options I would look at, remove excess weight.
Then decide on smaller tyres, re-gear the diffs, diff swap, or find some other way to re gear it, or put up with it.

1996 Suzuki X-90 (SWB Vitara different body)
was the 1.6L 4Cyl 5 speed manual
(which i believes my diffs were 5.12's)
3" lift - 30" muds,
100k's (on speedo) 105k's (GPS)

on stock tires 27" with the 3" lift
100k's (on speedo) 100k's (GPS)

By the sounds of it I'm either going to have to put up with it, or save up for some 235 75 15s
Got a quote for 650$ for 5 hifly mud terrains, looks ok too.

1.6 efi, SE swb vit with new 31s and 5:12 diff and 5 speed man. 100kph on speedo is exactly 100kph on a gps. Running a sv transfer to get speedo calibration. 100kph is 3000rpm, 110 is about 3400rpm.

31s in hi suck for hills, almost every hill you will loose speed. Get use to it.

[jimnynutter]

Hey shandy are you running a complete transfer from an sv or a speedo drive?

[shandy92]

Im running a complete sv transfer, you cant get the speedo gear out of the transfer without splitting it open. To make the sv case work in a se you need the male side of the gear from an sv. (The piece the cable bolts to). Does that make sense?

'93 JX LWB G16B manual running 235/70/R15 road-biased tyres, everything else stock - 100kmh indicated shows 97kmh on GPS.
