Hey I'd love to help you out, but I've already started on my next project......another Landy, so I'll probably be tied up for the next few years

Cheers, Murray

Great job. I have now done just on 19000kms in my Defender which we converted from a 300Tdi to a 4BD1T last year - the new set up is fabulous. Just a couple of quik quetios - first do you think that there is any advantage in removing the turbo outlet housing and repalcing it with a larger diameter dump pipe? (my vehicle is booked in for a larger diameter exhaust in the new week dv - I am running the old 300 Tdi system at present - only ever intended as a temporary measure) second what sort of fuel economy are you getting? ( mine has been averaging between about 12 and 14.8 lts/100ks)

Regards

G'day Christopher,
The dump pipe on the turbo is such a short distance, I don't think it would be any great advantage changing it, unless it is an unusually small diameter for some strange reason. From memory, mine is about 2 1/2 inch, so the size is insignificant leading into a free flowing 3 inch system.

The only time I've worked out my fuel economy so far was when I went to Adelaide towing a BIG tandem trailer and brought back my Isuzu 120. With all them hills and a tandem and another Landy on the back the fuel use was between 17.5 and 19 lts/100ks, but I was really working it very hard.
I'm currently in the process of working out the fuel figure when unladen......obviously I'm hoping it will be a lot less than on that trip.

10 years ago I did a trip across the Simpson Desert over 2 weeks from Geelong and back again with the 4.2 litre V8. When I got home, I had used $800 worth of petrol........and that was 10 year old prices too.

Cheers, Murray

Great write-up and good work on the conversion.

Outstanding! Loads of work, can you do mine? Makes me think that an aftermarket turbo for my isuzu will be more within my capabilities than a
4BD1T engine swap!

What did you use to sound proof the fire wall?
