Thread: Isuzu Truck motors ?????? drive train combos

So finding a Stage One would simplfy the conversion espeasially if it has a LT95 attached. So how can I best get one, anyone know of a dead Stage 1 with an Isuzu in it or perhaps a unregistered donor that is mechancally sound?

been two in the markets in the past month for $1500 in SA and $2500 in QLD respectively

Matt I hear what your saying even if I manage to find a donor it could handle far worse due to the weight distrbution and to top it off the costs are far beyond the value of the vehicle. This is sounding like as a conversion that is not as good as it may have seemed. Would the 300 Tdi be a better option with or a 200Tdi with possbly a different box attached to lighten the weight over the axels issues Could they provide less modifcations to fit and give a better SWB as a daily driver? From a previous Thread it seems that the 200Ttdi can fit realitively easily into the SWB and will bolt to the series box. Are there other gearboexs that would convert easily or are any of the later boxes going to offer up similar modification to the body and chassis as the LT95? I do understand that spares for these motors parts have become an issue. So the 300Tdi while more plentify seems more differcult to slot in partly due to it having to be mated to a non series box. More so than using the Isuzu motor transplant?

I take it you mean Stage 1 Isuzu the ones in SA were they just through papers or the Trading Post

[QUOTE=mudmouse;726598]G'day,

The 4BD1 weighs in at 420kgs + (sorry I don't have an actual weight) /QUOTE]

Isuzu say 325kgs fan to flywheel for a 4BD1 and 340 for a 4BD1T per spec sheet in the workshop manual. This mass does not bother the County's handling. Land Rover Australia give a maximum front axle weight for the 110 and County with Isuzu of 1300kgs for the 4x4 and 1500 for the 6x6.

I converted my V8 County to an Isuzu engine from a truck so I also needed a longer clutch pushrod. I'm sure there are more bits and pieces that I've forgotten at the moment too.

Great photos, thanks.
So the Landy housing has the starter higher to clear the chassis rails (my chassis was notched to clear the starter), the rear main seal is in the bellhousing and the clutch moves to the left hand side.

That clears up a lot of questions for me.
Does this bolt up to an LT85/95 or is there something else inbetween?

My 4BD1T rangie is 1170kg on the front axle empty. It's been that way for 15 years now.

Engine weight - Thank you Brian.

I think with any vehicle modification you do have to look at the cost versus the end result. But really, if you want 4BD1 then that's what you want and anything else is a compromise of your desire.

Other engine possibilities are the Isuzu 4JB1-t (see link below). I think these engines are available, new long motor for about $3k and were used in Rodeos until about 2003.

Grand Cherokee Diesel Conversion

This other link is a UK company with a big range of conversions. I think there's the 200/300 Tdi to Series conversion but everything south of the flywheel would need looking at considering the torque increase. I think the 'new' 300Tdi's are about $14k out of the box and I haven't had anything to do with 200/300's so I couldn't comment on their parts costs or reliability.

Land Rover conversions - M&D Engineering

About 15 years ago I tipped about $2500 worth of Nissan 5 speed into my SIII shorty. Now that was about what the truck was worth but it's what I wanted and served me well until I bought my '91 Disco in 2002.

Lastly, always have a talk with an engineer before you start. Vicroads should have a list of engineering signatories on their website. The NSW RTA have one on their books who helped me get my papers through - he worked at Solihull in the '60s and was a great help.

Hope these links help.
