You could also have "the best of both worlds" if you put the 300tdi engine in the VT sedan.

However, I think that would still be just as much a mismatch.

You did ask for opinions.

The following publications would get you au fait with what can be done with the Buick V6.

"Buick Power Source" Buick Motor Division, General Motors Corp. - Heavy Duty Parts List; Technical Data; Modification Details; Blueprinting.

"Buick Power Source" Buick Motor Division, General Motors Corp. - Electronic Engine Management System.

"The Buick Stage II V-6 Racing Engine." - Dave Emanuel, Performance Publications.

"Jim Ruggles' Buick V6 Performance Guide." - Jim Ruggles, Petersen Publishing Company.

Buick show torque and horsepower graphs up to 800 hp @ 8400 rpm for a turbocharged methanol burning Indianapolis engine, and a naturally aspirated gasoline burning drag race engine of 460 hp @ 7500 rpm.

I was almost going to put a Holden V6 into my BJ40, its a pretty common Hilux conversion.

Re petrol motors, I put a Ford 302w ex F100 & c6 Auto / lockup converter with Marks adaptor & G60 Xfer case into my 90 , F&R Maxidrive difflocks and thought it was the bees knees. Had a 4.4 P76 in front of a RR Box in a LWB.

Since then I had 3 Toyota Diesels 1HDT 4.2 liter turbo, 1HZ 4.2 liter NA, & Toyota B 3 L 4cyl and now my first Landy Diesel, the Td5 (chipped) .
Honestly the Td5 in the 110 has better useful power & WAAAAY better fuel economy than any of them, The only thing the 302 was better at was smoking up the rear tyres. Personally I doubt I'd go back to a petrol motor, or a V8 .

Thats what put me off buying a FJ Cruiser, they only come in Petrol V6 & The big cruisers only come in V8 now, which is ultimately got me back into a LandRover

A holden V6 110 Might be OK for a Day Tripper or Toolangi Truck but I would not want to go long distance touring with it.

I'm 28 and putting a supercharged ls1 into a p38, I've done plenty of engine conversion, a commodore v6 will not be worth the expense in a 2250+kg car, simple, I've put them in luxs, 2and 4 wheel drive, which they suit, but basically all the expenses are the same, except initial outlay for the engine, which is a small part

Building a stroked commodore v6? You money would be better spent at the pokies

My personal opinion is that they are a noisy, harsh and very unrefined engine that works well in a lightweight 2wd car, but kind of useless in a heavy 4x4.

Diesel is the way, especially a turbocharged one, infact Tdi is just fine

Well Justinc if the alloytec V6 is a harsh,noisy,unrefined engine ,then what does that make every Rover V8 ever made ? Ill tell you, a gutless,juice chewing pile of unreliable junk. If you were to look up a power/torque curves for say a ALLOYTEC 3.6 190 V6 and any Variant of the rover 3.9 you will find that at no point does the Rover engine come anywhere near the the holden engine in both TORQUE or Horsepower.
I Suppose its the silent shaft and Roller cam ,the 2 less cylinders and the smaller .3 liter capacity really didnt count for much !!!Lets not even go near the latest SIDI incarnation and compare that with a Rover V8.
Why is it that all these wives tales say its allright to have a Rover V8 that makes bugger all useful torque/Horsepower but you cant replace it with something (V6 alloytec) that delivers more torque , is twice as economical,across its entire Rev range .
Rovercares probably right ,dollar for dollar perhaps a ALCOA (LS1)special would be better
Rovercare ,you ever heard of C.O.M.E. racing , look them up in Melbourne and have a yarn about his 4.2 strokers ,say hello to Sam for me !!!

... That's a bit, um... harsh.


Sounds like agreement with my uninformed opinion that Land Rover got it wrong (with the petrol v8) and stubbornly refused to power the RRC et al with a more 'Fit for Purpose' powerplant... (as well as other bits and pieces)

Chevy offroad, no, the cost of buying a rolling kit to stroke a v6 plus machining makes it even more ridiculous, then you have a bitsa and again, what do I care about such miniscul cubes

They are crude, very crude efi, as crude as a 3.9 with 14cux

Again, have you put any in anything a ton heavier than a commodore?

It's not a viable or smart conversion by any stretch of the imagination
