Defender 110 Isuzu2.8 to 300TDi

DefenderItalia · Dec 21, 2008

Hi All - I have a Defender 110, formerly V8 and not with an Isuzu 2.8 TD + LT85 gearbox that I will be converting to a 300 TDi + R380 Gearbox. has any of you done such a work and what are the key areas that are to be ceful of. So far i am putting into the planinng:

ENgine Mounts
Chasiss fit for R380 box: mounts and positioning
Gear level tunnels
Piping, hoses, rad, intercooler
Electrics: Will I require the full ECU loom or I can run a 300TDi by clables

The reason why I want to change is because I want to travel across Europe / North Africa to go surfing - the bush mechanics (especially NA) know 300 TDis better

Any help here?

To be honest mate most people have done the opposite cos of the many blown 300tdi's.
The engine will not require an ecu (unless from a late auto disco. not recommended) just a feed to the distribution pump.
The rest is pretty easy if its a defender r380 as you can use standard propshafts.
The santana box if good is very strong and should sell well to recover some costs.

Hi and thanks for reply. In the process of planning, 2 further thoughts that you triggered: as I am replacing the LT85 with a Disco R380( should be the same as Def??) which will go on my current Disco Lt230 (aready on), will I also require the following:

300 Gear tunnel
300 Floor panels
new seat box
Propshafts?

I acan source all thoes very cheaply, but...that stats adding up? Although I have not heard of anyone that needed to replace the Box / shafts?

Let me know what you guys think

its possible you will need the tunnel etc as the lt85 is a massive square box compared to the r380.
Although if you are going to use a disco box the gearstick will be in a different place to the defender boxes. I'm not sure if they are interchangeable. they're not on an lt77 anyway.
also props might be a different lengths as well.

Why go from an Isuzu 2.8 to a 300 2.5? The isuzu will be quicker, have more power and no doubt more reliable and more fuel economic!

Hiya...interesting question....that would be mainly because when I go travelling the mechanics across Europe / North Africa will already know the 300 engine, plus all Isuzu spares and repairs are becoming mode difficult to source - See description of items for sale in For Sale section.

Ahh! Just make sure you take a couple of head gaskets with you just in case!
