Thread: Tdi Replacement engine

80-90 ks on the f3. Mate I had a stock standard 94 TDI with 300.000 + Ks on the clock with a 5 speed and it would sit on 100-110 all day no worries. Before a dozy female wrote it off i drove from Townsville to Sydney on straight veg oil sitting at an average speed of 11O, With two drivers, in 25 hrs. Once again no problems. I would take it and get a compression test before you start spending big.
Good luck

Where can I find the numbers on the different options to see what the difference in power output is? The 2.8HSE motors were $11-$15 landed, then you have to fit it. May as well go and buy a TD5 or PUMA

I've heard some good and bad of the 4bd1/4bd1T option. I know guys here like it, but it's an old engine and I don't know how you'd go with rego fitting an older engine to the car.

So for now I know I want to keep it diesel and I want a turbo. Other than that, I'm wide open to suggestions. Would the gearbox need to be changed with any of the below options?

Get your 300Tdi sorted. Maybe some new injectors would help. Check the turbo hoses for delamination and leaks. It will be your cheapest option by far.

My Defender will also sit on 110kph all day long, and will easily get up to 120kph for overtaking.

If your 300 tdi can't get up to 100 km/h then it is sick. Apart from the obvious problems that you are experiencing which cannot be ignored a 300 Tdi is capable of doing highway speed.

Hopefully you will be ok with a head gasket repair, if you get to the stage of taking the head off you should get an indication of wear on the bores. If it is worth doing the head you might want to consider the bottom end as there are some concerns as to the robustness of the bearings.

Thx all,

I am now convinced that keeping the Tdi standard and focussing more on the turbo and other power enhancement option is the way to go.

Does anyone know where I can take the head etc. for machining if required and also a good mechanic that can rebuild this engine if required?

I'm in north west Sydney.

unless of coarse your towing a decent trailer on a warm (not hot by outback standards) day on a FLAT road.

I had to sit on 90-95 to keep engine heat at bay heading out to Roma...it wouldnt go much faster than that either....overtaking .......hahahaha yeah right, unless you mean the 3 trailer road trains that passed me like I was in 2nd

oh and yes the engine was in good working order, well maintained as was the radiator...it had a 3 inch madrel bent exhaust, larger intercooler and slight up in fueling.

this in a 98 110 trayback

for those that have a tdi defender WITHOUT egt gauge and still running a OEM temp gauge....just because things seem fine doesnt mean they are

if you are going this route: you will obviously have a budget, make sure you allow for some of that going to upgrading the cooling and intercooling system....in stock form on a stock 300tdi they are marginal at best

Here is another option
Land Rover /Range Rover ISUZU 2.8 Turbo Conversion Kit - eBay 4x4 Accessories, Exterior, Car Parts, Accessories, Cars, Bikes, Boats. (end time 23-Jun-10 08:56:00 AEST)

Stronger easy to tweak with Intercooler etc, more low end torque.

Its a bit out of the way but take the head to Bruce Davis on Annangrove Road, he helped me out with my engine, he sorted he head and fitted new everything to it. I cant remember how much the head alone cost though.

I would get him to look at your injector pump if you want some more grunt, he can do one of his tweeks and give you a nice jump in power, costs about $800 or an exchange injector pump with the tweek done was $1200, but this was back in feb 08.

He can then do a manifold and turbo mod that works with the injector pump mod for a further $2000 which gives the engine a nice amount of power.
