Landrover 90 + volvo d5 engine

[welshjohn]

Hi

I have a mate who has got himself a 2003 90 defender minus engine and has the opportunity to purchase a volvo v70 d5 with a smashed up rear end for cheap.So basically would it be worth dropping the volvo lump into the landy and is this even possible?

thank you

Yes it would be worth doing and yes it's possible.

However it all comes down to how much time, money, motivation and skill your friend has. I'm fairly certain that a Volvo D5 will not bolt straight up to a LR gearbox. Then you've got wiring, cooling, transmission, sump clearance, exhaust, inlet, clutch, flywheel, starter clearance, engine mounts etc etc to figure out.

I think really your mate needs to be doing the research as its a massively open question that doesn't have a straightforward answer.

thanks for the reply
My mate is a decent agricultural/foresrty mechanic so i think his skills are good enough.We presume we could use a lot of the landrovers parts intercooler etc even some parts of its loom.But the hardest part we think is the connection between engine and box ?

A Volvo D5 isn't a simple engine so unless you run some sort of aftermarket ECU then you're going to need the standard engine management to get it to run. Then there's bound to be immobiliser issues and possibly CANBUS problems or OBD2 incompatibility with the Defender that will need to be worked around. It's all doable but I wouldn't assume that the wiring will be simple.

In terms of the physical connection I imagine that would be relatively straightforward - get a spare gearbox, offer it up, have an adaptor plate made (or make one) if necessary. Sort a clutch that will bolt to the Volvo engine and will fit the input shaft of the gearbox. Make sure the spacing is right and a starter will work - sorted.

Isn't the Volvo engine transverse? That will create other areas that will need work. But as I said, it's all doable.

If you want an old D5 gearbox (and engine bottom end for that matter) to play with or cut up before you set to with the real thing, let me know. I've both lying around in my garage.

Thank you for the parts offer will in form my chum..

RIght then the Volvo has been purchased its. V70 d5 with medium rear damage but a huge dent I between the doors with 76'ooo mls on the clocks a fully history so engine runs like a peach.got it for £650 on a private sale.he wanted it for the 7 seat conversion for his family v70 plus the alloys.but seem as he had the 90 and the Volvo turned out to be a diesel the idea was spun. Electrics should be pretty ok due the another mate with top degrees in electronic engineering.how would go about finding the correct clutch? Would we also need to know which way the Volvo engine spins..


Thank you

You want to be a little bit careful, because any modern reasonably high capacity turbo diesel will turn the std LR gearbox inside out at the drop of a hat! I can't remember what a TD5 engines torque rating is, but it is pretty pony compared to some of the more sporting passenger car common rail engines!

If you plan on doing any significant off roading, you also might want to check on the oiling system on the Volvo engine. A deeper, baffled sump, and possibly some external drain back pipes from the cylinder head might help out a lot at extreme angle or operation.

I would think he's probably ok with a standard D5. Depending on which model it is, they tend to get going after about 1,800 - 2,000 rpm, so won't have the very low down torque that may damage the gearbox.

People re-map the TD5 and boost the TDI without too much issue, theres a 90 with a modified 300tdi engine in it near me, I struggle to keep abreast of it in my 170 bhp tdi (from standing/rolling starts anyway), although he might have uprated the gearbox, of course. It's obscenely quick off the mark for a battered old Landy.

Whereabouts are you? I haven't yet taken it out of the car, but I'll be scrapping the shell in another couple of weeks hopefully.

The D5 Volvo engine is likely to be the 163bhp version, so a quick check shows that it produces 251 lb/ft of torque compared to the TD5 which is 221 lb/ft.

It might be worth looking to see whether the D5 in the V70 is any different to the one from the XC90. While the XC90 is obviously not designed for the sort of off-road stuff that a Defender can do, its engine might well be modified to some degree.

Love the madness of this challenge!

Then news so far:
Matey has purchased the donor car and stripped it of all the bits that are needed.And a local motorsports car builder has said that he can get the landy box and volvo engine mated up.The project is still in the design stages at the moment so will you all up to date on how it's going.

The LT77/R380 are rated to 380nm.

Indeed, i had assumed being a 2.5l lump, the volvo engine was a bit beefier than it is.
