Hi all,

I'm considering getting a 2.6 and from what I can gather it is only modestly more powerful than the 2286cc 4 pot. I expect it'll have more low-end torque but spares aren't as ubiquitous as the 4 pot and I'm wondering if it's worth the investment. Has anyone experience of both? How does the 2.6 pull?
 
I've just acquired a Series 1 with either a 2.6 or 3.0l straight six Rover in it. Only started it for the first time last week, but I'm amazed how smooth it is, had it ticking over quite happily at about 350rpm. Sounds really nice too. I've got to sort the brakes out, MOT and I'll be away. Can't wait.

World of difference .......BUT horses for courses

the six pot is smoother
Has a heap more low down grunt
is more relaxed on the motor way
sounds fantastic (think fat v8 burble)
isnt THAT much thirstier than a 2 1/4
BUT ...............

some bits (exhaust fannymoulds ) are hard to get hold of if they ****ticate themselves
you need one that has been looked after ,and continue to look after it I.E.

landrover 2 1/4 = designed to be owned by farmer palmer ,and treated like his tracderrr ......ans still start and run when abused and fixed with baling twine and pig **** stick

landrover six pot = designed to be fitted into a rather expensive saloon car ,and thus cosseted and looked after by the local garage ,oil changed at regular service tintervals ,etc etc .............

In other words ,neglect a 2 1/4 and it will carry on working ........do the same with a six pot and it will die expensively ;)
 
If you are actually thinking of swapping a 4 for a 6, bear in mind that the bellhousing are different, so they are not a straight swap.
 
Exhaust fannyfolds (I like it) can be made with stainless steel. Been told by a chap that has one they'll run very nicely on gas.

Andy. :)
 
going through a steep learning curve here putting a 200tdi in a 109 6 pot.....after setting up the motor I found......bell housing different dia, bell housing from not transferable from 2a 2 1/4 (though maybe from series 3 4 pot?), different clutch assembly, lugs for engine mounts appox 6 1/2'' further forward on chassis (todays discovery....bugger!) and though its not a problem for me the bulkhead is different. 6 pot has much deeper rebate in the centre to allow for a longer block and the footwell cheeks are angled differently, dont know if you'd squeeze the thing in without radical redesigning of the bulkhead with a big hammer.

Having said that I got a couple of 6 pot gearboxes if that helps....
 
ino it probably a stupid question but has anyone ever put a 2.6 in a 88 series 3? or are you guys talking about swb conversions ?:)

2 years......how time flies :rolleyes:

Doesn't make any difference if you're talking swb or lwb......If you want to put a 6 pot in anything that wasn't built with one then you'll need to cut off and move engine bracket mounts on the chassis, get a 6 pot gearbox and radically alter the bulkhead
 
years ago i put a six in a s1, it fitted on the gearbox and the bulkhead but i had to move the mountings, i put the rad in front of the cross member. It was a lovely thing to drive and good on petrol. It looked awful and i should have cut the bulkhead and moved the gearbox back.
 
I have fitted a 105s (straight six with twin SU's) into a 2A, I don't remember altering the bulkhead and the six pot bell-housing was a straight swap, they are the same bolt pattern as a series one but the latter gear box's have larger lay shaft bearings.

The bolt pattern is the same but the lip diameter is different, not by much, but different.

I suppose it's possible for a 6 pot to fit onto a standard bellhousing but not for a 6 pot bellhousing to fit a 2 1/4 flywheel housing. The diameter of the lip that fits inside the flywheel housing is definitely different.....too big one way so no fit, too small the other which probably wouldn't matter

The bolt pattern is defiantly different on a 2 1/4 the top bolts are at 11 and 1 o'clock verses a S1 which has the top bolt at 12 o'clock. I never noticed the bell housing lip being wrong, though I never checked. I put a Rover 90 in my 107 and never had any trouble, but a mate who put a 3 ltr in his 109 had some machining to do. made a nice motor though it had a Weslake head and a 2 inch SU and did pull well.
 
fair enough, and yea didnt notice the last post was in 2010 but, iv always like these engine and would like a 109 lwb 2.6 but dont realy have the room for annother!!! :(
 
I had a Rover 3ltr straight six in my 109,straight onto a 11a 2.6 gearbox.
A lovely vehicle to drive,smoth and pokey,but when 4star went so did the engine and now its got a Rover 3.5.
All in all it's just as economical as 4pot,and a lot less weight.
 
yeah i remember years ago when i was a youngster my dad used to do car repaires in a shed on a farm and they had just took delivery of a brand new 2.6 ragtop landy the paintwork was in a wierd colour ( powder blue ) for some reason and it had to be out of site aswell for some reason or another, anyway my dad was restoring a 1955 s1 LWB and making his own hard top as it was a pickup when he bought it from hallam bros and had to move his s1 out of the shed to do a repair in there s11a SWB and the farmer used the 2.6 landy to pull it out of the shed as it had no engine and no brakes and had to tow it up an incline and the rope they where using to tow it with snapped and the s1 smashed into the side of the farmers humber super snipe :eek::eek:
