Engine conversions

Hello everyone I've brought a p38 as project offroader/expedition am looking into more power options is it worth tuning the 2.5 turbo diesel or go down a new route with it looking for advise

lol... you bought the wrong engine m8, you needed a V8....

Get a V8 l322, they go like stink when they work
and they look good on the drive when they don't (which is most of the time).

Depends how much power you want. My 2.5. Was very sluggish when I first had it. Hasn’t had anything drastic mainly just maintenance and shifts now. They can be chipped and boosted up a bit but it’s alot of work is cheaper easier to get one that already has a 4.6 and couple Jerry cans if you want big power.

Sorry being and done the v8 route looking to see what power I can get out the current engine but also being looking at possibly changing it to the bmw 3.0d engine samenas in the e46 3 series as they produce good bhp and torque and very tunible not sure if there any conversion info or kits availble

No real need for massive HP if you're looking at an offroad project..

A mate of mine has a 95 DSE and it worked quite well offroad even with 32" wheels.

A chip on the 2.5 will get respectable torque figures 134hp and 275nm is hardly a power house but a chip gets you near 160hp and over 300nm which is good enough..

Hi, I run a "working" yes "working" L322 V8 on LPG..... I love it! Would I get it dirty... probably not, for that I have a 98 P38 2.5 with a power chip, gives me about 30% more bhp. They is what they is, I still feel I can hose down the P38 if needed and the L322 is a weekend cruiser... slippers must be worn. I have had loads of RR, the 2.5 in auto is a little sluggish but pulls very well and tows like a goodun! Expedition vehicles don't really need more "get up and go" as it's about dragging **** and peeps across stuff or hours trundling down the autobahn? Being a P38, conversions aren't straightforward and not that popular as the prices on original stuff is rising. Chap near me is struggling to sell his Isuzu power P38. I have owned Troopers, Cherokees, Discos and Mercs in diesel form, the P38 is a lively option compared to all except the ML which wasn't great off road but went like stink on it! Back in the day when I lived in Devon... fook me, 30 years ago! The popular conversion was with American V8 diesels.. 6.2 etc but that was into classics and two doors which is easier than a P38. I personally would invest in a decent radiator and hoses plus the best battery money can buy and work on keeping the P38 reliable, yes Range Rovers are reliable, don't care what anyone says... tends to be unreliable owners! I have never had issues with my RR experiences... if they are looked after!

More working early L322 about than X5 or ML. They are a doddle to work on, parts are cheap and any inherent issues are rubbish BMW parts, stamped bosch and made in China! I have had my 4.4 for a couple of years and wouldn't part with it, great cars. Not sure what the whole reliability debate is about... I think it is peeps who buy a RR for the first time and then rely on the Stealers for every little thing... then they become expensive! The only expenses I have had are consumables and servicing... had a gearbox solenoid fail but that was a bargaining chip when I bought the car, £20 and fluids.. sorted, other than servicing and a few cosmetic changes the car owes me nothing. Would I buy an L405, nope! The L322 has exhausted the RR design remit and everything that follows is just imitation and corporate generic tat for the masses! Yep, I'm looking at you Evouqey thingy and the new rash of Defenderfreelandervelar stuff, won't be long until they make a city car or just a re badged Smart? I personally would stick with a P38 as an off roading and expedition vehicle. I think they are slightly more robust for that kind of work being a ladder chassis construction and parts are slightly cheaper plus I would rather ding my P38 than the L322.

Need to be careful of the HP22 box on the diesel. Some HP24 are pretty much straight swap. Then chip it, bigger intercooler and good service. Maybe tweak the waste-gate a quarter turn but probably safest not to.

Once setup right you won't need much more power, especially in low range.

I do like my range rover but I do think they are more high maintenance than anything else. My one has had about £1500+ of parts (no labour) in one year and is still broken.

Helps to buy one that isn't too broken to start with... always costly fixing other peoples breakdowns! Maintenance is more costly than your average car because you have bigger capacities to fill. If you have spent £1500+ and it's still not fixed then either your trying to fix stuff using the.... I'll buy cheapest thing first and keep going until I have fixed the problem, which seems the approach used by Garages these days or you bought a complete Lemon? I would love to know what you have spent your money on?

Welcome to land rover, if it's around twenty years old and is starting to be rebuilt. I bought mine for 3500€in 2016. It costs me 1000€ a year and no labour a year. It goes like a tank and is reliable. If you look after it it'll look after you.

If you want silly power out of a 2.5 you prep it up and bolt an Holset HX35 to it.

Silly is the right word: silly lag followed by silly torque!

OM606 would fit in there nice

You are surprised? When new they were aimed at a market that had more money than sense
