The engines are expected to use a litre of oil between services.

Further, they are not a rebuildable engine. Single use only mate.

Pffft, still an apprentice there? I also have a mate you works at Fishermans bend with GMH in the engine dyno/tear down/test bit:p

Yep, the early LS1 used oil and rattled, actually most of them rattle, they're built loose (aids performance and emission), but they rattle for 100's of thousands of kays,

1 use only? WTF? I mean, so when I pulled mine down, had the crank machined, new bearings etc I must have been dreaming;)

Don't base or spread crap from an early model, get annoyed when someone says Land rovers are crap/enreliable/leak oil?:D

They ARE the perfect conversion, for a rover, just a shame that the crappy ZF HP22 can;t handle the HP:mad:

10and a bit:1 compression, +zero deck height, awseome open heads, fantastic engine management, I pulled mine down and looked at porting heads and blueprining while it was apart.............nope, no need;)

Just a cam and springs, the standard valve springs are soft as butter:mad:

And they fit into a fender engine bay nice, there should be some picks on here of mine on this site somewhere when it had the gen3 sitting in it with the T700/LT95. Just got to make the rear drop truck sump clear the draglink, which it does easily if the motor is positioned back correctly.

How does putting a lightweight compact Chev. or Chrysler into a Jaguar in place the long, high, grossly overweight, and very obsolete Jaguar engine "upset the driving balance"? The US small block V8's are lighter, more compact, more powerful, sit their centre of gravity further back and lower down than that of the Jaguar engine. A proper installation needs reduced height front springs to restore the ride height because the V8's are so much lighter than the Jaguar 6. An added bonus is that front end weight is so reduced that you can if you wish disconnect the power assist from the steering system.

TD5 tuning seems to be pretty easy, but say 250bhp versus 450bhp is still a big difference! I also cant fit a larger intercooler as my high mount is so far back into the grill.

Cheers
Pete

hhmmmm i hope he says no to the LS otherwise i will cry:mad:

otherwise she'll be a gobsmacking beast:twisted:

He was busy when I called earlier so we will have to wait until tommorow!!

No, as a matter of fact he is now a road tester/service advisor with Mercedes Benz after having done a couple of years with BMW and his time as a qualified mechanic with GMH, including being one of two people within his dealership qualified to do the Gen 3 rebuilds.

When I refer to single use I mean that the bores cannot be machined, so if there is damage to the bore due to piston slap etc then it's a replacement job.

Right,

Spoken to an engineer, and he has provisionally said.......

a maximum of 5800cc

:)

(few conditions but looks promising)

Will update a bit more lately. my laptop has failed tho so I am borrowing a colleagues) not much access at the moment

Pete

gggrrrrrrrrhhhh!!!!!!! Wat the...............

doh, wish i spoke to your engineer!!!!

dam, well pete now you have no choice bu to do it:twisted:

hey he may let me and a mate supercharge our 4.4 & 4.6's then? maybe we can keep up with you then;)

keep us posted bud.

There's an ls1 in a defender here in Perth. It's in the latest issue of Perth Street Car, my mate and his workshop did some of the work on it. Wa Performance.
The early ls1's were pretty useless. Mine has a cam only pulls 367rwhp in a heavy vx clubby.
I think it would be a great conversion !
