A thousand questions from a newbee (driving a diesel Land Rover)

[uksoundz]

I have a TDCi, and doubt P&G would work too well, having a DPF just makes things worse.

Engine off and coast downhill I assume is fine ?

[yostumpy]

yeah. Just pumped up my tyres, 44 rear, 38 front, taken off mudflaps (x4) and this makes a big difference to the rolling/coasting. Doudtless the roofrack is hold me back, but those mudflaps whoa, 144sq inches each x 4. blowing in the wind.

my diesel SUV is much older 1986 and has a much different power band from a modern diesel.

so this may or may not apply to your auto?????

for me rpms, gearing and load is a major facter in what speeds and loads get good or bad mpg, im 60hp at 3,000 rpms max hp is 80 at 4,200rpms and 125 torque at 2,200rpms in a 4,300lb auto. so yea im slower then dirt
other then that i have more limits being a older auto, i have next to no boost under 2,200rpms. so at times, down shifting to get rpms just above 2,200 and backing out of the throttle will get better mpg then trying to use the next higher gear at WOT with no boost, on a up grade.
where other times using high gear on a flat road at a steady speed way under the 2,200 mark gets better mpg.


also, ive found with the trailer in tow, i have no idea if you pull any trailer.
driving 100% as a 4speed trans can net better mpg for as long as i keep my rpms reasonable.

I had another landrover a while back, bought it in 2001, but it got stolen in 2006. But in 2005 I splashed out and had a s/h Isuzu trooper engine fitted into it. It was the 2.8 td 4JB1 engine. This was a luverly unit, quiet, powerful,started like a sewing maching, and gave very good mpg, usually on a bit of run, regularly got 33+mpg. I find the landrover 300tdi engine rather agricultural in comparison.
just read your bit underneath, about wanting to import 4JB1 engines. I bought mine , and had it installed , by ' mervin Burgins,. Burgins 4x4 ? New & Used 4 Wheel Drive Specialists. Chevrolet. Isuzu. Landrover. Mitsubishi. Sales and Service across Powys, Herefordshire, Shropshire and Mid Wales. In Wales, uk. He may have some s/h units still, that he could export. He does like to haggle!! (well I do anyway) (look under engine conversions)

[trooper Tdiesel]

ahh thank you for the info....


what does

Price for conversion is £4950 + VAT

i know what VAT is having gone to Canada but is the £4950 UK pounds or some other cerency
and did that include buying the engine in that doller amount?

i know some people have goten the 3.1L as well the 4JG2-T, having the bigger gen2 trooper they want the extra 20hp for the extra 1/2 a ton of auto and more sound friendly to your ears.
but sence im in a cold climet and have gen1 troopers. i like the idea of direct injection for much better cold starting ability and better mpg.

kinda funny to hear some one say the computer free 4JB1-T that was sold 1987 and up in some country's. is less like a tractor engine then a newer computerized TDI engine.
just goes to show, how ahead of its time it was.

[yostumpy]

Yes it was a luverly engine. The block was wrapped in a rubberised coat, kept the noise down and the heat up. The website is a company based in Wales, in uk. The price would be £4950+ vat (english pounds), but that is for the conversion, with them supplying the NEW engine and doing all the work to your truck. Obviously not YOUR truck. So one might say the engine was £3500 + vat @20%, ( which you prob wouldn't have to pay if it was exported). You may also get a good deal from japan direct? I've often said that if my engine blew up catastrofically, I'd have one of these fitted again, but it'd cost what my truck is worth. often get s/h ones come up on uk forums and e-bay. trouble is you don't know what your buying. would you want new or 2nd hand?

[trooper Tdiesel]

i have been looking at the JAPAN emisson take outs. so yea used.

Japan deals with emissions in a very strange way.
when you get to 40,000 - 60,000 miles....you are required to replace your engine or get a new ride. or something along those lines.


the big issue ive ran in to is the 2.8 and newer Isuzu passenger car diesels where never sold in the USA as a on road engine. only as a off road engine.

we only got the 2.2L and 1.8L diesels, with the older MSG trans tell 87.

since the 2.8L uses the MUA trans and theres no way to put a MSG diesel housing on a MUA trans, we have to get the trans with the engine......OR......
they used the same trans even with the same gearing in the USA with the 2.6L gas, so really all we need is a pallet or two of the diesel housings. and buy the engines with out the trans.


where trying to get a group buy, this will be the 2nd time
1st time was 4 engine/trans combos.

very good rite up on the 4JB1-T swap in to a USA spec Isuzu trooper its about as close to a bolt in as it gets....going from gas to diesel.

I have a 1998 Defender as well (300Tdi Hardtop)
It has done 405 000km (300 000km on engine)
I get about 10.5km/l under normal conditions, but I am looking at ways to squeeze 13 to 14km/l out of it.
I thought my 10.5km/l was average, but not particularly great. Looking at the consumptions quoted here, mine looks quite good.

I am however forced to use the Defender to commute (110km one way) into Johannesburg CBD on a daily basis for a while, and with the fuel price the way it is, I want to get by on a tank per week. (80 liter)
