v6 commodore conversion for rangie

[SWAMPRR]

has anyone done a conversion like this b4 ...i know the V8 has been done...it sounds silly putting a V6 in place of a V8 but the advantages that i can see are:

hugely improved fuel economy
lower registration costs
close power figures :

258nm@2500 / 112KWs@4750 RR 85'

293nm@3600 / 127KWs VP - V6


cheap to get parts for
cheap motor and gearboxes - $1200 aprox..
reliability and ease of diagnosing problems - fault codes / limp home mode
EFI ! - no more carby problems on angles or on hot days
smaller motor - lighter?
stronger gearboxes

im just suggesting this as a conversion...i havent really done any research however i did have a hilux with one of these motors and it went like a shower of Shit. !

holden V6 = the 202 of the new century

cheap, gutsy, reliable and everywhere

just watch the fuel economy. imo they get good economy in a commodore
only when used on the highway as they will go into self tune. when fitted to a bigger less aero vehical they may not do this as you could be running on a power region of the fuel map. (when cruising on the HWY)

close power figures ? wtf - not even in the same country

For the cost and hassle of conversion, a rebuilt 3.5 with a few tweaks will out power it and be lighter to boot.

Bear in mind the commodore has the torque peak 1100rpm higher.

Bolting in a 3.9EFI would be easier (and possibly cheaper), and give you better power and torque in a 4x4 (especially offroad).

[RaginRover]

If you put a commodore motor in you need to mate it with the th700 gbox, without that they are very doughy off the mark as they don't produce enought torque early on - otherwise I wouldn't do it

just a thought, both motors are from buick DNA, could the bellhousing pattern on the rear of the block be similar? hence no adaptor plate needed?

I think the rover housing is the same as the early 60's buick pattern but the V6 uses the later pattern - i have a 79 buick V6 and the b/housing is not the same as the rover V8.

Marks 4x4 adaptors make a kit for a disco to put a commo v6 in. I thought about it cause i got a hydro turbo700 (wit manual valve body and cable shifter ) on the floor of my garage jus waiting to be used. Great to be put in my rangie out in the yard rusting away (its okay, they are aluminium). Decent power and economy.
