Hi guys

As you know i am looking at getting an LWB soon and although i have mentioned about getting a 4 cylinder petrol and later fitting a tdi engine i have also been thinking about the 2.6. petrol and stage one V8 varients aswell.

i know the two big petrol varients will be less fuel efficient than a tdi in a 4 cyl model but i am thinking the gearing in the two big petrol varients will be more suited to long motorway jerneys for when i go to my caravan with a landy full of peeps and stuff than a tdi'd 4 cylinder one and i walk to work anyway so it won't be used as an every day car so fuel wise i should be ok, so anyway here are my thoughts.

(1) if i was to get a 2.6. model how would it perform on long jerneys.

(2) if i was to fit a 3.0. rover P5 ( same engine to the 2.6. but more powerfull ) what would the differance in performance be and would there be a differance in mpg or will it be the same.

(3) if i was to get a stage 1 V8 in std form how would it perform on long jerneys and how would the mpg be against a 2.6. / 3.0., without going overboard what would the best mod be to the V8 if needed :)
 
I took a trailer from the midlands to Aberdeen on The arse of a LWB 2.6 Only had to fill up 14 times Much better on return journey without trailer
 
stage 1 v8 wont have the low down power or grunt of a tdi and will be lucky to see 20mpg, stage 1 would be a good base for a tdi conversion using a disco box and engine, plus u can run on veg oil at 70p a litre :), 70p a litre 32mpg so the equivalent of 64mpg in a petrol motor...

i much prefer towing with my tdi than either the v6 or various v8's ive owned

yeah i never gave that a thought, so would the 200 tdi mate up to the stage 1's range rover gearbox ok and will i need to do anything with the engine mounts ie are the mounts on the stage 1's chassis in the right place for the 200 tdi engine mounts as it sounds like a great combonation as the gearing will be better for motorway jurneys with good economy aswell :D
 
Ok i have looked into fitting a tdi into a stage 1 but its going to be to much work for me really as i thought the tdi would more or less bolt straight in but will have to fit a different gearbox to suit the tdi engine so have now decided to can that idea :eek:

Anyway going back to the stage 1 if i was to get a stage 1 will fitting uprated cylinder heads alone give it more mpg as i have hered that slightly uprating the 90 bhp V8 to the next stage will slightly improve the mpg as part of the reason the original stage 1 V8 has poor mpg is because its been de-tuned to 90 bhp or does it intail more upgrades or is this a complete load of bullsh1t :)
 
shame your not in the market for a 88 series 2a in original condition just needs minor attention like seat covers and wiper motor sorting out and the brakes looking at for the MOT

£1200 round the corner from me :eek::eek:

no i meant 6 cylinder stage 1 is an lt95 is yours v8 id fit lt77 or r380 and lt230 in stage 1 with a tdi

no such beast as a 6 cylinder stage 1..... stage 1 is a v8 as stated using the lt95 4 speed, no matter what u do to the v8 its not going to improve much in mpg, the restriction comes from fittings placed in the intake manifold, easy to pull out if they are still there,

tacking tdi engine mounts is easy, and the stage 1 would at least give you front cv joints meaning full time 4x4 and 5 gears

£500 would get you a rotten disco giving everything u need including engine mounts, gearbox, rad fuel filter etc etc, sell n scrap will get a few quid back after

cheers steve
 
Right so its looking like back to plan A then, the problem i have with all this is i can't weld and the type of fabrication needed to do this is beyond me so in the long run it would be better staying with the tdi into a 4 cylinder lwb and try and get the best gearing i can.

it was just a thought i had originally with the 2.6 to rover 3ltr but that looks like a waste of time in the long run then at the same time i thought i would ask about the stage 1 V8 and even the posibility of converting a tdi into the stage 1 aswell but in the long run even if i could weld and good at fabrication it would take a lot longer to complete and end up being very expensive aswell which is a shame really as if the stage 1 gearbox would have mated with the tdi the gearing would have been a good match for the tdi i think but ha ho.

anyway thanks everyone for going out of your ways explaining things to me i really appreciate it ;)
 
stage 1 box wouldn't mate to a tdi, hence ive just sold my similar lt85 5 speed, shame as the lt85 is probably the strongest normal box you can get, as you clearly know the petrol 4 cylinder to tdi is relatively simple, definately need an overdrive and 3.54 diffs though if you are going to do many motorway miles... just done my lightweight from start to finish over 48 hours a simple nut n bolt swop

having previously owned 6cyl and stage 1 V8 sw , from a mpg point of view pretty much identical which will be half the mpg from a tdi . The plus points of both is you travel a lot quieter, and both are quicker . As the point of low down grunt was mentioned both exceed the tdi at low revs. From point of view of retrofitting to a lwb a non starter HTSH
