commodore v6 into range rover clas

[zook4fun]

who has put one of these into a rrc? how did it go with fitting. did you use the auto of rover box? i have found a adapter for a th400, 4l80e to the lt230. my car is a 78 so it has the 4speed/lt95 i think and would like to keep this xfercase if i can.

i'm looking at the vt supercharged 6 ( 171 kw @5200 and 375 nm @3000. weight is about 170 kgs) as i'm sick of trying to track down parts for my 3.5l and i haven't even got it on the road yet! had to wait 3 weeks for a gasket that showed up last week and now waiting on more parts before it can go over the pits

power and torque in the commo v6 are all wrong for a 2t 4by. They fit ok but the end result is no better than what you have in terms of performance or fuel economy

[zook4fun]

i mean no offence at all but have you ever been in a commodore with one of these engines in it? the calais (weights about 1500-1600 kgs) i drove the other month when helping my step father ( ownes the car) happy pulled a 300 kgs( empty) trailer with about 2 cubic meters of top soil in it and still got 14l per 100ks. thats pretty good in my book, better than the p38 i have with nothing in it.

they have a lot of power down low, about 125 nm more than the 3.5 for 500 more rpm. thats more than the last sierra i had

[Loanrangie]

Going by the bore/stroke of the V6 it should be a goer but possibly change the cam and fuel map for more low down torque, T400 wont fit to a V6 as they used the GM X body fwd bellhousing pattern, a T400 to lt230 adapter may fit the T700. You cant keep the lt95 unless you plan on either using one of the cut down ones used in the BW/C4/C9 auto conversions or custom making the adapter.3.5's are easy to get parts so you must be looking in the wrong places ?

[6.5 rangie]

T400 adapter won't fit a T700, they are different, probably better fitting a zf and making an adapter for that to the v6. Personbally i think this is a waste of time (i drove a loaded up v6 VZ one tonner, gutless), if your going to the effort stick an injected 5litre in, more power and probably better economy.

Oh , i have a T700/ Lt95 adapter and trans case sitting in my shed i'm thinking of partring with

I had the pleasure of driving a couple of these commodores around at an old workplace. They averaged around 15 litres per 100km when driven empty. On a 30km open road trip they'd still use at least 4 litres. These weren't supercharged.
That's in a vehicle pushing about half the air of a typical landrover product.

Isn't the peak torque of the old 3.5 around 2500rpm?

[zook4fun]

as for parts in in the ACT right now and no one stocks bits for them so i have to order them in. the gasket i got was the oil pump gasket and it got "lost" in the mail 2 times before i got it.

peak torque of a 3.5l is at 2500rpm but is about 125nm (248 nm @2500 rpm new from what i can find and my engine is tied) less than the 6 at 3000 rpm. i'm not looking at the normal v6 but the supercharged 6. they are 4 bolt mains, rolla camed and last to 250,000 300,000 ks before needing a rebuild, about 50 kgs lighter than the 308, make good power with very little work and will be a lot easyer to get tick off than the 308. i have played with the 308, 304 before and might go that way with a th400 if one comes up for the right price.

6.5 rangie that engine is the alloytech engine not what i'm looking at it is built to rev a lot higher than the s/c 6. pm me with a price about that adapter. i wont have to cash for a bit as i'm moving house right now but will keep it in mind

vz is 3.6 alloytec and yes they are less "torquey" do have a little more up top. apparently the tune was changed in VE to get a bit more pull down low.

zook4fun the s/c 3.8 can put out a hell of alot of power with smallish mods (boost pully, injectors, f/pump, tune and rockers) something different go for it!!!!

[6.2troopy]

go for it mate. i just sold my s/c calais. with a small amount of work it was making 161rwkw and 550nm of torque. more than enough to have fun. and like i said that was only alittle bit of work. these motors can be made big these days!

let me know how you go. i would be interested in putting one in my disco if im going to keep it.

[GRIMACE]

you could spend the same money on the rover donk and be happier imho... who wants to downgrade to a 6 from and 8... NOT ME

[chimpboy]

I think it's an awful idea. No offence. It is just not a desirable engine, and it's as much work as putting a desirable engine in would be.

You need to change suppliers, try Land Vehicle Spares near Sydney. Even if they don't have the parts the longest wait is going to be a week. If they have them in stock,then the day after tomorrow. C.O.D. too by the way.
Ordered some brake pads on Fraser Island last year, 3 days, and they didn't have those in stack. Not C.O.D. that time.

The money you would spend on the conversion would buy you a really sweet supercharged rover v8, and you wouldn't have to worry about electrics/computers/adaptor plates etc.

Also, I've never had to wait longer than a week for parts, and some have come from overseas. Check out AULRO for their list of reccomended suppliers.

Had a 3.8 Th700 Lt230 in a rover chassis under my last Zook.


It was a 84 four door RR that was damaged when i got it ,
The first gear on th700 is the lowest you will get in an auto and the box also has a .8 odd overdrive so ratios work in well .

Give Tony (Ruff) a pm they made a couple of adapters up for the
moon buggys they biult with the v6 donks.


I like soup , bits n pieces mixed together make it yummy .

are they a road worthy adaptor of for 'offroad use only?......

[Dozoor]

mine was an engineered conversion while it was an 84 RR , nsw

The Guy who made the one i had was a retired machinist ,

He used the RR for touring .It had done two trips to the cape from sydney
with no issues.
