Thread: HS 2.8L TGV turbo Diesel ?

What about getting the pump completely overhauled? I heard of some impressive gains from people in melb. So get the pump done, get the defer gear into tranfer case and bang in the P38 cooler for the tranny...

Geez I sound like a pro.. but im not. Just lots a readin on this forum

i totally agree on the idea of a lighter engine and keeping it further back. God only knows why they punted the 300tdi forward.....

i also think the 4BDIT is a great engine,but not sure about the weight and vibes???? i also like the idea of a auto, so considering the price of chev v8 on crates they certianly could be viable......yes the fuel consupmtion may be different but really compared to a 300tdi that blows up, how much is the cost of fuel in the end.......especially spread out over time

Probably using something from here unless I can be bothered making the adaptor myself.

The engine bay of the 200Tdi defenders did look a bit silly with the engine so far back and the huge cowl - I suspect they just moved it forward for aesthetics???

I love my 4BD1T, and wouldn't change it. It is heavy, it vibrates a bit at idle (but no more than any other engine when driving - and much less than my 2.25D on the highway). If the front axle is laminated/strengthened, then the weight causes no issues.

The weight balance gives it more understeer than other defenders IME, but no biggie apart from that.

In almost all situations the massive amounts of low down torque of the 4BD1T more than makes up for any weight or CofG issues.

Well, thanks All for you comments...I am going to hijack my own thread and go off on a tangent now The basic challenge I am facing is poor power from the D1 when towing, seems as though I can get a good power increase with lpg injection...first up I thought the idea of conversion from diesel to lpg to make no sense....however, it is not so much a conversion as a simultaneous injection of diesel and gas at the same time.

interesting dyno results and info here.

The 4JB1T is probably a cheaper option than the TGV and capable of equivalent performance.

thanks isuzurover,
i would like to drive one but dont no anybody with one i was also told 4bdit would just eat my R380,is this rite 4bd1t was my 1st thought after seeing the build on members ride section a while backof the intercooled 4bd1t but was kinda put of by some of the negatives would the 4jb1t be a reasonable swap or would it just be easier too go 300tdi with upgraded turbo and intercooler....

My two cents worth - slightly back toward the topic - "Motor & Diesel" in the UK offer a 2.8 "rebuild kit" for the 2.5 TDI (crank, pistons etc). Requires boring the block. Cost is about 1500 quid - they have one on UK ebay at the moment. This plus turbo and/or intercooler upgrades may do the job....perhaps. I dunno if anybody has imported one of the kits. Cheers

Yes 4JB1T would be a good swap. IMHO a much better engine than the 300Tdi.

With an intercooler, larger exhaust, increased boost pressure and injection pump adjustment (similar to what people do with the 300Tdi), they perform very well.

I put a 300Tdi with VNT turbo and upgraded intercooler in my rangie, but was not happy with it for towing on long trips.

I have swapped it with an Isuzu 4BD1T, but if I didn't already have the 4BD1T, I would have used a 4JB1T. If I was doing it again, I would seriously look at the 3 litre, 4JJ1-TCS out of an Isuzu NLR or NNR (or the 4JJ1-??? from a D-Max).

would the new common rail diesel be alot of wiring and electrics. i'll have to do my research as i have the time just want a nice no fuss daily driver dont get me wrong my 4.6 is smooth and fairly quiet its just thristy and i lose a fair bit of space with gas in the back.thanks for the thoughts

The surprising thing I have found out (from experiments) is that you can do a Diesel Enhancement LPG kit using standard (petrol car) conversion components, you don't need patented goofy kits at all! I used to wonder why it was so dear to do diesels, the kits are mental in price. Now after 6 diesels I know it can be done for around 1/2 the price commonly quoted. Admittedly fine tuning is a bit of a black art, but I have a mate with a TD4 converted Classic and he is very happy.
