Thread: stage 1 isuzu

G'day, welcome to the forum.

If you're thinking about using the mechanicals from the 109 in the County, then the cost should be minimal as the only modification you'll have to do is replace the V8 engine mounts with new one's to suit the Isuzu.
This thread will give you a basic idea what's involved >> County V8 to 4BD1turbo conversion <<

If you're keeping the 109 as is and planning on buying all the parts required to convert the County, then it will most likely be a costly job.

Cheers, Murray

Thank u very much Murray for the reply + link. I may have to ask u more questions in the near future.

1. LT85 can be used with the Isuzu, but is liable to problems unless some care is used in driving. LT95 much better.

2. LT85 is a completely different box with a separate transfer case and an extra gear - the LT95 has an integrated transfer case.

3. Isuzu box is certainly the pick as far as strength goes, but a lot bigger job.

4. The Rover/Isuzu special bell housing and flywheel housing are slightly more common than hen's teeth, but not much. May become more available as the army replaces its Landrovers with MB over the next few years and both vehicles and spares are sold off.

Hope this helps.

The LT85 is sorta alright with the 4BD1 with the 4BD1T you'll probably need to get something stronger.

As I have posted before, my LT85 lasted ~240k km behind a 4BD1. It was then fully rebuilt. I believe the problem was stripping the mainshaft splines rather than agearbox failure. A new mainshaft was fitted as part of the rebuild.

It is now at ~420 000 km, half of that as a 4BD1T, and ~10 000 km of that towing a 5 m boat. Including plenty of 4x4ing.

It is still going strong (touch wood). Some of that may be due to running Syntrans.

Or a tribute to your sympathetic driving!

You may want to retract that John... (though I do try and drive sympathetically most of the time, however the gearbox got a hiding that weekend)
