Outer Limits 4x4 Board

Hi guys does any one know witch Isuzu diesel 4 pot engine to repower my 1965 2A I want to retain the 2A box, is there an adapter kit around that I could use? has any one done this here thanks.

Cannot help with an Isuzu but I understand that a 200TDI diesel out of a early defender or disco is a good option. I think it will bolt straight up to a standard series landy box but I am not sure.

The 3.9 isuzu out of a series 3 stage 1 or a county mightv also go in.

In suggest you ask on AULRO.com.au as they will have all your answers.

4JB1T would be the easiest to fit size-wise.

They're a 2.8l turbo and will shift the vehicle along faster than you need. The non-turbo versions will be slightly cheaper and even easier to fit.

hey i have an isuzu 3.1l turbo intercooled 4cyl diesel for sale complete with auto trans 66,000 klms its a 4jg2

The IIA box is fairly, so most isuzu diesels will rapidly destroy it - not to mention the gearing will be too low.

I know someone who fitted an ISUZU C240 (?) diesel to a series LR. They are about 2.2L I think. It was OK, but not much better than a good 2.25D.

A 4JB1T would be a good option (and much better than the 4JG2T), but you would need to change gearboxes.

Thanks but I want to keep the 2A box as I have a pto winch that runs of it and it damm great winch. I was thinking of going the transfer gear conversion with thr higher raito gear and usind a Isuzu diesel engine.

Does the PTO run off the box or the t-case?

You can keep your t-case and convert to a stronger box.

But if you want to keep your box, then I would recommend a small, smooth running diesel, and being very gentle on it.

You can get a few conversion kits here:

As mentioned, the 4JB1(T) is a great motor. The lowest spec one put out about 60kw and 230nm. Power should be fine, but the 2A layshaft won't like the torque much.

The PTO runs from the gear box not the transfercase I think I will have to use the smaller Isuzu motor that was listed and be easy on the g/box. Iam not going to use it in extreame offroading lol.

Assuming its currently fitted with a 2.25 Petrol.....

They are a great, indestructable off-road motor which is perfectly suited to a 2A. They will go well on the road as well with a bit of breathing improvement. Mine would easily cruise on 110 with just a set of extractors and a holden carby with adjustable main jet.
Maybe it just needs a freshen up? Yes they're more thirsty than a diesel, but the fuel savings will NEVER pay for the conversion which will cost you at least 5k just for the engine and fiddly bits.

Even a small diesel wont cope with the low gearing of a 2A and it will be an endless and expensive cycle of upgrades - gearbox, diffs/gearing brakes etc.

Not necessarily true - I converted my IIA from a 2.25P to a 2.25D. It cost me $600 for a rebuilt short motor (ex mining company warehouse stock), $200 for a buggered long motor (donor for electrical and fuel systems, etc) and about $200 for other bits. Engine uses about 9-10 l/100km as opposed to petrol which was 15-17. EDIT - so assuming you save 5l/100km on diesel, and diesel costs 5cpl more, then I paid my conversion off in under 20000km.

It performs very well (with a few tweaks), and on the last trip I beat a mate's (almost identical) IIA with a 2.25P up the cunningham's gap by miles (started about 300m behind him). And I have 33's and he has 32's!

If he's talking about a 4JB1T or similar + a conversion kit +++, that will cost 10x what it cost you to put in an old landy diesel which bolts straight it.........

But I agree, the 2.25 D is a cheap way to go, if you can put up with the noise.
They're also getting hard to find......

Is the later 2.5 (pre 200tdi) a bolt in?

Mark - I thought he was talking about the small ISUZU C240 I mentioned - which is practically bolt-in, and there are kits floating around for almost nothing - but performance is only on-par with a good 2.25D. Also - some (industrial) C240s are limited at very low revs - so beware!

KB - AFAIK the 200Tdi is practically bolt-in - apart from moving (or raising) the battery tray and doing something with 1 engine mount (?)
