4BD1 to ZF adapters

[justinC]

Is anyone interested in 4BD1 Isuzu diesel to V8 ZF auto adapters? ( RR classic and Disco V8)

Currently making one for mine and will produce several if anyone interested.

like Jim said.

Will the adaptor bolt onto a landrover motor or one out of an isuzu truck.

[Loanrangie]

The isuzu truck and l/r engine are one and the same with just a few mods for the conversion, bolt pattern is the same. Justin, i guess this will also bolt a 4bd1 up to any V8 bellhousing ? - lt95, lt77,lt85, T/flite as well as the ZF, with just the clutch or flex plate needing adapters etc?

I was under the impression that the flywheel housings were different. Are you positive they are the same?

[Loanrangie]

Yep, i know of a couple of guys that have fitted non L/R isuzu's using the l/r bellhousing.

Not sure on price yet, I haven't got the bill for mine yet!

This 'Kit' will be for a direct replacement of a V8 Rover engine in a RR classic ZF auto,with an ex county 4BD1 diesel, and does not include mounts etc, only crankshaft/spigot adapter and plate between box and engine. It retains the V8's flex plate for converter mounting, and requires the removal of some of the lower bellhousing on the auto to facilitate the bolting up of the converter.

I'll try to post pics when I get it back, and before I attempt to sell any, I'll test it thoroughly!

And as regards the manifold etc MAG, Available from Turboglide in NSW, about $400 including some studs etc. The Garret TB25, about $1300.00, And the intercooler, HYBRID brand, 77mmX580mmX250MM (approx) with 3" inlet/outlets was only $550.00 ( Had to 'make it fit' the front of the Rangie!)
PM for more details.

Be sure to let us now how this works out.

[justinC]

Engine and box hopefully trial fitted this weekend, Exhaust system and suspension sitting on the floor next to it....

All I need is TIME and Sleep!

[Loanrangie]

How are you going with the conversion? do you know how much the adapter will be yet?

ISUZUROVER referred me. Can you let me know how it turns out when you are completed with the "transplant?" I am interested.

Thanks.

What's the progress so far?

Since the HP rating of this engine is slightly better than a 300Tdi (120 vs 111) is this good enough to get V8 performance in such a setup? And I don't mean 3.5 carb performance.

I was considering a HS 2.8/ZF setup for the 110 300Tdi but that's pretty pricey

So, how much do these motors cost and where do you get them?

You still won't have V8 performance, but it better than a 300Tdi, especially in the low-down torque department. At one point I owned a 110 with a carb 3.5 and an NA 4BD1, and there was a noticeable difference in acceleration. The turbo version would probably be pretty close to a carb 3.5, and you could always add some tweaks.

I have no idea about the US. In OZ they were factory fitted to SIII Stage 1's from 1982-1984 and 110's from 1984-1989. Other than that they were fitted to ISUZU NPR 5tonne trucks, and also popular in gensets. They are a reasonably tight squeeze in a Land Rover.

[artm]

I need to take a ride in a fellow chap's D90/2.8/ZF and see how much pep that has. Then we'll see what Justin has to say before I decide.

They are plentiful here in NPR and GM trucks, and with an automatic..

It's off the line where I need help. I need to step on the "gas" and shift quickly to avoid pissing off the guy behind me. Once I'm at 60-70 mph I'm happy. I know I'm stressing the heck out of it off the line but I also think it can't do 70mph comfortably for the rest of its life.

JC,


Any update???

[will_warne]

I've got an HS 2.8 tgv in my truck. Its reasonably peppy (on a manual box) but its still a 2.5 tonne Landy. I'm going to be tuning it soon so I'll let you know how that goes.

Seems he may have dropped off the end of the earth - which Tassie is pretty close to !

mines a early 81 build and is fitted standard

Hi Art and all...
No I haven't dropped off the earth, yet. I'm trying to juggle a booming business with family and everything else, so I don't have much free time at the moment, I still check the Outer limits from time to time though.

All in all the conversion was worth it, but having broken 2 ZF autos in 15,000km I must say I am suprised. I had been warned about the damage that torsional vibration can do to torque converters, and I think that this is the sole problem apart from experimenting with governor weight to promote early upshifts, that I will encounter.
The transmission was pulled down to find 1 cracked planetary gear support and some evidence of slipping/ heat on the clutches. The torque converter lock up clutch was completely US, and the rear sprag is a little 'loose' now. This , I might add was a 285,000km old much used auto that was the original one in the car, and for about 160,000km had a ripper of a JD 4.7 engine with lots of go in front of it. It was beach sprinted in soft sand, used for low- range' holeshot' traffic light runs with Nissan Skylines etc.( Yes they always won, but it was great to see the look on their face as I could stay with them to about 65 kmh!!) I think I could forgive this one for running out of drive on a few occasions!
The second gearbox that I fitted was a low mileage second hand unit that I fitted while on holiday, at All 4X4 spares in Newcastle, ( Hi to all there!) and was very grateful to them for their help!!! This transmission lasted all the way up to QLD, central QLD, Cape trib, Camooweal, Lawn Hill NP, Normanton, Karumba, Mount Isa, Mary Kathleen, Cloncurry, etc and thenm all the way back home again, Towing 1.5t caravan / off road trailer.
It only had a problem after I wound up the boost to 15Psi, and pumped enough fuel in to it to chirp the 235/85/16 tyres in drive at the traffic lights! I was about to take it out on a test drive with the pyrometer hooked up and there was a big cracking sound as I loaded it up...OOPS.
SO, after all that, I'm getting the first box rebuilt, and will spend some R&D time getting the governor weight right to get the shift points right and pressures right etc...
To those contemplating this conversion, it is a fantastic offroad performer with the torque of the 4BD1 and the midrange urge with the turbo makes a huge difference on standard. I would challenge anyone to drag the van we had on the back into a headwind at 100kmh, while doing 2000rpm, and getting almost 20 mpg ,with a V8. The joy of the 4.7 is sadly missed, but getting 900 km from 130litres of diesel is roughly twice the range of the V8. I can always drive my other toy, a P6B 3500S Rover if I want to hear that sound...

Any further enquiries, I'll try and check the board more regularly.

Regards, JC.

[Loanrangie]

Thanks JC, nice to hear you are still alive. Sounds like a great tourer, what was the economy like when not towing ?

[Rangie Thing]

Hi There, JC i would like to get put on the list for that adaptor. just let me know price and postage Im looking to bolt it to a 4 speed manual LT-95 in a RR.
Thanks Rick.

P.S. you should put them on ebay.

[Loanrangie]

Thanks Rick..

All you need is a factory 110 isuzu county bell housing for the LT95 - no need for a custom adapter.

[Rangie Thing]

Thanks loanrangie, I will have to keep my eye's open for one.
I don't know what way i will go yet 4b1d-t or 1uzfe toy v8.

[ISUZUROVER]

Good to hear from you Justin. So do you still have plans to produce the adaptor?

Do you have the pyrometer hooked up? What are the temps like? If I remember correctly you have a 4BD1 with aftermerket turbo? Hence no oil spray to the pistons? Are you running a tweaked 4BD1 pump or the turbo pump with aneroid?

[justinC]

Hi Ben

No, I'm running the standard nat aspirated pump with no aneroid. The reasons behind this notwithstanding the costs of such items, are simple reliability. I will set the boost back to 10psi, the minimum I feel for the fitting of an intercooler, and so far I've not got above 600 degC with adequate performance. ( Upstream of the turbine) On our trip, the standard wastegate setting was only 7.5Psi, and with only small pump adjustments and (Yes I'm VERY bad for doing this, but I ran out of time) the original 430,000km never-been-serviced injectors... I was able to achieve 19MPG at the worst, and 24Mpg at the best, usually towing at 100 kmh because this is when the trans went into lockup...

When the auto shift points are sorted, and the low stall converter is fitted, and the injectors are replaced, and the wastegate adjustments and fuelling is sorted, THEN I'll be happier.
The auto trans shift points and lock up point is the key to a conversion like this with an engine that won't rev too high, as the torque is about 2100 rpm, the box must shift earlier than the standard V8 one at 2/3 throttle, not always trying to drop down a gear. My mistake,(And I new it at the time) was to try and control the shift points with the kickdown cable, and this only led to slippage and failure of the gearbox. The governor weight is the key to it all, and I'll concentrate on that this time around.
I'll keep you posted once she's back on the road.

Ben, my 4BD1-T does not have the pump with aneroid. It has been suggested to me that this is normal for Australian models.

At one point I had in my posession a pump with aneroid, given to me by a mate who didn't need it - I am 95% sure it came from an Australian 4BD1T, not an import. I was going to install it when I turboed my 4BD1, but didn't get time before I went OS, so I gave it back to the mate.
