What RR p38 to buy???

Hi all i'm new to this forum and need some advice really. Im goin to buy a P38 soon but not 100% sure which one to get i.e. 2.5dt or the 4.0 V8. Ive heard that the 4.6 arn't the best. Could someone please give me the pro's and con's on each 1 and what to look out for when buying 1.

Many Thanks

Danny

diesel slug without tuning box, v8 slip liners/head gasket and after owning a range rover p38 they break often.
realistically v8 is 14 mpg and 17 mpg driven like a pussy

What RR p38 to buy??? MINE!!!!

No mechanical advantage between 4.0 and 4.6. Same block, liners etc., just a different stroke. Just think about it..do you want to move 2 ton from a standstill quickly or are happy with a plodder?
Irrespective of whether you go 4.0, 4.6 or 2.5 diesel there are plenty of problems on the forum relating to each. The petrol heads have overheating problems, the diesel truck drivers moan of overheating and warped/cracked heads and intercooler problems and the LPG freaks moan about running and fuelling problems so take your pick. The diesel is no more economical than the petrol and their owners are constantly posting about re chipping and "Powerboxes" which tells me they are vastly underpowered to their petrol counterparts.
For every instance of "Slipped Liners", "Porous Blocks" etc. there are many owners who have no such problems...after all, most people who post here have an issue, the ones that have no problems have no need to bother.

In my opinion, for what it's worth, my 4.6 on petrol costs no more to run than a diesel with my driving style.

currently been a 3.9 disco owner and a 2.5 rr owner(2 months).i bought the rr cheap with the idea of doing it up-selling it but bearing in mind i drive a v8 3.9 disco,i,ve decided to keep the 2.5 sluggish rr and sell the disco.so there you go the 2.5 can,t be that bad,yes its a little slow but only off the mark,once you get it going its great and yes you can can chip em which by all accounts makes a massive differance.like a fellow member said theres good and bad in all but i personally would rather take my chances with the bmw lump.no matter what you buy be prepared to dip deep into your wallet,things do go wrong.2 months into ownership i,ve done the matrix o-rings,front air bags,and both heater blowers.BUT EVERYTIME I SIT IN THE DRIVERS SEAT IT BRINGS A SMILE ON MY FACE.

As Above I too have had a Disco V8, TDi300 & now a 4.6 P38.......

Diesels are ...Well, Diesels..... PLODDERS will pull you up hill towing a tree!!!

Disco V8 /4.0 ??? ... Tries it really does but a tad "Unrefined"

P38 .... 2 tons of Armchair about 3 feet off the ground, would pull yer house down & turn round & stomp on the bricks fer fun!!!

As Irish says taint alot of difference between Diesels & Petrols (MPG wise) personally I fill it up & drive & when its empty I fill it up again if I was THAT worried about MPG I'd have bought a Moped!!!

The 4.6 sounds a tad "Sweeter" than the 4.0 ( Softer "Burble") just my opinion mind ........

At the end of the day it will be YOUR choice .. My personal advise ...... GO LOOK AT ALL OF THEM 4.0 /4.6 /2.5TD's ... you'll soon arrive at a decision & KNOW whats a good un & whats a Lemon.....

You'll decide on the Estetics (What it LOOKS LIKES) NOT whats under the hood

Look at it this way ....You go & look at 2 P38's

P38 A is ..... tottally outstanding in looks equipment & bodywork but the engine is faulty..

P38 B is.... Completely Cream Crackered in its bodywork the Trim is Shagged but the engine is 2 months old & done 27 miles & BOMB PROOF

Humam nature says you'll go for "The Nice Lookin" one (P38 A)coz you want people to "Admire it"......... & YOU THINK it looks great!!!!


See, tell me that aint Soooo True..... This Human Nature thing is a CURSE when buyin a car!!!!!

I wanted to say that Claw but me fingers aint in synch with me brain this time of night.....It's me age (And the brain deterioration)

totally agree

For myself an un-tuned diesel is ok, as most of my driving is done on empty-ish roads and not always accelerating or braking with traffic. But maybe best for you to try both flavours before deciding. Easier said than done: but try and get a good long drive in each, and whichever you go for, check, check, & check again. There are good `uns out there, but a dog will cost you dear. You don`t say where you are, but maybe someone near you could accompany you if you`re out looking. I Know I`ve benefitted by having a friend knock the rose tinted specs off my nose when looking at cars.....

Diesel every time, chipped they go well, fewer problems than the V8 and they are economical, at least mine is in my opinion.

thats what any owner will say. in my opinion mine is best ranige in the world, great on petrol fast smooth quite a beast. i would say in my opinoin v8 is best..

i have had a v8 and am on my second diesel .i much prefer the diesel at least 30 % better on fuel and like i always say if you want speed get a sports car .Which ever you choose the most important thing is to get a good one .It is possible !!!

As Irish says, there's no mechanical difference between the 4.0 and the 4.6 other than stroke, but the 4.6 is more powerful and more economical.

You're no more likely to get problems with a 4.6 than you are with a 4.0.

How is 25mpg not a larger number than 18mpg then?

I wondered about that ??????

A good friend of mine has a 4.0 now for the guts of 8 years and loves it. I lent him mine for a couple of days as his wifes car was playing up and they needed a car.
When he handed me the keys back his main comment was how much easier mine was on fuel round town as he didn't have to stop at every station for a top up. He says he going to change now to a diesel, possibly going for an L322.
