Thread: Discovery I to Isuzu 4BD1T

2 & 3 are not the case, the Disco is just the same as the 110

1, would be a matter of sourceing the correct starter

1) Starter on the engine sitting to low and out. Which I am sure it will hit the chassis.

2) The oil sump. I know that in a 110 the engine goes without any modification to the oil sump but in the Disco the front axel is located more aft interfering with the oil sump.

3) The streering box need to be relocated?

Does anyone know of someone who has done this engine swap on a Disco I. Like I said I have seen this engine swap on a 110 but never in a Disco.

Pictures will help

Can someone help.

Land Rover had different flywheel housings made that moved the starter up to clear the chassis.

I have seen pics that I believe were posted in this forum of the 4BD1 in a disco. Sorry I don't know who it was, but I save the pics.

I'm guessing your starter is 24 volts and is held in with 2 bolts. The 12 volt starter to suit the Landy flywheel housing is a 3 bolt pattern. See pics here >>>>>>>>>http://www.aulro.com/afvb/isuzu-land...onversion.html

Also, 4BD1/4BD1T's are known to be very hard on autos.

I think I've emailled you this stuff, but I'll put it here anyway.

Landrover flywheel cover (engine bellhousing) puts the starter higher. My rangie uses the Isuzu bellhousing with a direct drive starter motor (it's more compact) and the chassis rail has been notched to clear.

You'll need to pack the bump stops to restrict the last 20mm or so of suspension movement to keep the sump clear of your axle. I've fitted longer bumpstops (big orange suckers) which I bought from the UK.

Most of us have the steeringwheel on the right, so the steering box fits nicely beside the engine.

Why? the truck sump is deeper? or the motor is mounted to low?

Thanks you all for the quick reply. First the starter, my starter is a 12V that is held in place by 3ea. bolts. Obiously I dont have the LR flywheel cover which brings me to the next question.
Would it fit using the Isuzu flywheel cover and replacing the start unit with one more compact?

My Disco has the steeringwheel on the L/H side. Does any one knows if the engine will fit with the steeringwheel on the left side?

Another issue is the auto transmission most people agree that it wont last long. Whats your take on this? Have someone try to use the auto transmission of the Isuzu truck?

What about the L/R flywheel cover they are easy to come by in Australia? If so what is the market price?

Onece again thank you for the replies. The engine has been sitting for a year now and I am ready to get it install.
Any comment, pictures & ideas wheel be greatly appreciated.

My motor can't go any higher or the thermostat housing hits the bonnet. The truck sump does have a thick rubber isolation gasket on it (stop noise transmission from the block to the sump) but with standard bump stops the diff head can contact the lower corner of the block, not just the sump.

JC on here has broken a few ZF autos behind a 4BD1T - he has posted a thread or 3 on the topic. Dougal has also suggested that a heavier flywheel may reduce torque pulses at low revs and reduce stress on the gearbox.

The bellhousings (flywheel cover) are very difficult to find over here.
