Would a Petrol fit instead of Diesel?

My 1996 AFT with a Diesel 2.5 WLT engine now needs some major work.
So i'm thinking a new engine, but, would a petrol engine fit rather than the WLT?
Thanks

It will fit, but need a lot of parts from donor vehicle such a petrol tank, fuel lines, electrics for fuel pump, ECU, coolant pipes, rev counter, exhaust and ignition system etc. There may be some gearbox changes with the ratio or the point where the gears change. It may be cheaper to get a second hand engine shipped over from Japan.

Hi
Ziggi...
The same thought had crossed my mind, should I need a new engine, and i think you'd need to look at an engine / gearbox replacement, and re-vamp the cooling system entirely...My choice would be to look at the physical dimensions of the Rover V8, as fitted to early Land-Rover, and the Rover 2000...something without complicated ECUs, although the Bongo one is fairly rudimentary from what I'm told, then the rest is down to using a more straightforward cooling system, with piping running forward, rather than dipping under the vehicle...The rest is down to getting a custom propshaft, and juggling. There must be a stack of good breakers where you are, and knowledge to tap.
The Bongo is an excellent vehicle to play with in this respect...just time to do it!
Cheers
Helen

Hi
Nah....just a cheap engine with available spares...maybe a Holden engine...just depends how easy it is to find someone who can cope with that sort of work....but Aussies are an ingenious lot

V8 Bongo, that sounds (literally) very appealing.

Whos going to be brave?

Hi
V8 Rover power and torque are not dissimilar (from memory) to the Bongo figures, so not a lot of difference...but a better engine.
Cheers

If you want to swap to a different engine I've been told it's best to look for a "marinised" engine as they have all the electrics etc. packaged into one module and do not need to be patched into the vehicle electrics at all, other than to supply power and control wires. They also usually have their own fuel pump etc. so do not need fuel tanks to be changed either.
So it could be worth asking at a boatyard or marina for a suitable unit.
All you then have to do is find a way of cooling it that doesn't involve driving through deep puddles and blowing the hot water out of the exhaust..................

have to agree with scanner, a little izzuzzzzzzu diesel would be good,very adaptable at the backend.

Hi
Sounds like a good plan!...plenty of good marine diesels...I like Perkins diesels!
Cheers

There are a number of different Volvo 5 cylinder engines, the early ones were made by Audi. A 163 bhp D5 would be a nice unit, but they are usually mounted transverse, so quite a bit of work required.

I'm glad this question has been raised. The fuel economy is not good, and the engine is pretty antiquated.
I thought perhaps the VW 1.9 TDi or 2.0TDi in 130 or 170bhp guise would be a good option. Hopefully giving more like 35 - 40mpg, and a bit more ooomph. But I take the point over all the ancillary stuff needing to be sorted. The Rover V8 has been so modified, that that would be a great option, apart from the 15 - 20mpg.
The Volvo/Audi 5 cylinder diesel engine is already used in the VW Transporter vans, so a good option, though they only do 35mpg at best.
What about a gas turbine engine from a small helicopter? Probably run it on any fuel you like !
hmmmmmmmm

Good luck with your search for a suitable gearbox............
