Just a warning to those of you thinking of fitting a 2.5n/a .I was told it should just plop in.... but it don't. Had to make my own engine mounts cut a lump out of the chassis on o/s engine mount and reweld that.Loads of more cr*p cos it was a petrol before,then theres the exhaust to adapt,and now after a weekend of fitting it the gearing is sh*t 4th gear is like 3rd gear and the gear box was poor but now is suffering cos of all the extra torque.So i think the only way is to fit range rover diffs . Oh and sort the bloody gear box out! Why aren't things simple??

A different engine seldom "plops in"despite what people say. I put a 2.3 petrol from a 90 into my Series III, virtually the same engine, but it didn't "plop in" Nothing like the problems you had, most only took a minute thinking about, and involved buying new bolts etc (in a couple of places the 90 bolts were the wrong length, but as it was metric I couldn't use the Series ones. The biggest problem was heating the bottom hose on a saucepan to stretch it onto the bigger water pump ouytlet.

I fitted a Sherpa 2.5 NA into my 88 with only minor probs, it was a diesel previous so are the engine mounts different between Petrol and Diesel???



Gearing, just put bigger tyres on, dont go too big as hills will be taken slower..

I think the Sherpa fits Series better than a Ninety , something to do with the position of the injector pump, I believe that is why you need to change the mounts with a ninety lump, fortunately for me not a problem with petrols.
Of course a bit dodgy for series off roading, in particularly wading, as the timing belt cover isn't sealed.

The Sherpa engine is rated as more powerful too.

The injection pump sits much higher in Sherpa engines.
Dead easy to get at.

I never adapted my exhaust, just swapped the inlet and exhaust manifold onto the 2.5 (Again straight swap) and used the series exhaust...

Would gouss the exhaust manifold on the petrol would be the same as the diesel??

Not on Series motors.
But the same applies, the complete petrol Series manifold bolts straight onto the later engine. Presumably losing a bit of potential performance, but that wasn't why I was doing it.

when u say sherpa engine is a better fit does that just mean the old type sherpa or can u use one of the newer LDV types which looks like the same van as i might change the engine on my series 3 at a later date if not what engine would u say is the best transplant and why

Mine was an early engine, not sure what is in the LDV's now...






Just a thought, are the gear ratios differnt for a petrol engined Landy, as the engine is higher revving than a diesel????

I have just finished this conversion today !!
I had a 2.25 diesel which died so i decided to get a s/h 2.5 N/a Diesel which was fitted today .

Problems i came across were

Battery tray has to be removed, and the engine mounts need quite a lot of work to fit the chassis and engine correctly, a small bracket needs to be made to accomodate a accerator cable and thats about it.

I havent driven it yet but after reading the first post reference the gearing problems , i am worried i have made a terilble mistake putting this engine in !!!

There was a period in the 80/90's when they fitted the Land Rover engine in the Sherpa, that is the one that fits in. Over the years the Sherpa has had all sorts of motors fitted, ranging from BMC B series to Peugeot. I'm not saying these engines can't be fitted in a Land Rover (almost anything can) but it is the LR engine that is a popular conversion.

The peugeot engine out of a LDV 400 will fit Steve Parker does (or used to) a conversion kit for it.

The SHERPA version of the LandRover 2.5 NA diesel engine driops right in to any Def 90 , but the Sherpa inlet manifold isn't good, so finding a Landy Inlet is a big help.

The Sherpa variant 2.5NA Landy motor is rated more powerful than the Landy Landy version, AND the injection pump sits much HIGHER in the Sherpa version which makes it all easier.

BUT ..... the timing belt cover is NOT sealed in the Sherpa version. This means it isn't watertight, but you can change the timing belt without stripping out the water pump.

People shouldn't be treating LandRovers as if they are submarines anyway.

Thats funny, cos i never needed to do anything to my engine mounts at all when i did the conversion?? My accelerator cable, ahem a piece of welding rod bent to shape....

Battery tray, yeah I had to cut mine about, put a lump of ply in to raise the battery above the injector pump, a bodge but it works.

If you are on 750x16 tyres I think you will be OK, mine purrs along at about 55, though I have bigger tyres on so i lose a lot of go on the hills. My 2.5 needs an overhaul, so I will be fitting a Diahatsu 2.8 TD in the near future, that aint gonna be such a straight swap!!
