Ok, we all hear about the weaker boxes in the HZJ105 cruisers but how much stronger is the box in the petrol or T/D cruiser.
Ive had enough of the no power 1HZ and want to up grade to a petrol cruiser,yeah yeah i know but dont care and it will work out cheaper than turboeing the 1 HZ and will have a heap more power BUT is the gearbox really that much stronger(and for that matter I think the front diff is also stronger??).70% of the time it will have our camper trailer on(around 700kgs) and Yes I do tow in 5 th gear but am very careful about the conditions I drive it.Is the 5th gear in a petrol cruiser more capable towing,again to the right conditions.
Will be looking for a 4.5 2002 manual cruiser to keep the live axle.
Cheers all

I think the 4.5 has the H151, and yes it is far stronger, totally different design. 5th gear is part of the main cluster i thnk so the box has so should be fine for towing. Also has internal oil pump and is physically larger.

Yep, like Davo said. The diffs are the same though :-(( but I think they are a different ratio.

Plenty of auto FZJ105s around if you're interested in a change.

I've got a petrol 105 and I reckon it's a beauty. They go like stink and have huge reserves of torque. I just climed a steep dirt hill a few days ago towing a tandem trailer grossly overloaded with rubble. I intentionally bogged it down to 800rpm in 2nd H and plodded up the hill to show a mate of mine just what the petrol donk will do when crawling. However - stir them along and they are a bundle of fun as well. I don't think you'll regret it.

Unless you've got big cubic inches or a six cylinder CRD turbo, diesel's start to give me the sh*ts after a while too.

got a 1hz, aftermarket turbo & 240,000km. Did the r151f (light), gearbox and replaced with H151f (heavy) from a v8 petrol. Got heavy gearbox and transfer (pump for oil ,not drip fed!) as well as turbo flywheel and clutch (much heavier) . all bolted straight in (with different bell housing) and retained old drive shafts with no mods. Gearbox is significantly bigger than old one . Unfortunately has raised engine revs by about 500 @ 100km/h. Diff ratios in newer models are 4.11, mine (live axle) is 4.33. I think i will look at changing mine at later date, hopefully to 3.9/ 3.7's ???, to get cruise speed (95-100km/h) revs down to around 2000rpm. Above all very happy with my conversion, and to be honest cheaper than doing my old box up!!. I can also travel in confidence knowing it is all heavy duty and if need be parts are easily available (ie: clutch). My 2 bobs worth!! keep it real, regards Kirsten (NSW)

Can you just put a Marks Adaptors overdrive on it, instead of changing diff's?
Thats if they make one for this model.

Cheers Pesty

To be honest Pesty, i have not looked into that option, not sure if another overdrive can be fitted to a 5speed??, If so could be cheaper than changing both diff centres and speedo sensors etc etc. Thanks for the thought. regards Kirsten

just a clarification
All 1hz's (troopy,ute,wagon )run 4.3 diffs
all v8's and turbo's manuals 4.1 diffs,but have different g/box ratios(lower first gear)
the auto's run 3.9's,so if anyone wants to shop around for different diff ratios this may give you an idea what to ask wrecker as far as vehicle availability goes.
