Thread: Conversion, has anyone done it?

A mate of mine had one of these engines and 4 speed autos in a Kingswood ute. Lots of work, but a nice engine/trans combination.

At the back of my mind I have Gen III 5.7 with 6 speed manual floating around. I think that would be pretty good in a Classic Rangie (mine, specifically ).

I've found the Gen111's (and the GenIV's) in manual form to be a dissapointment due to the big lack of low down torque. - I would definitly want an auto behind one of these in 4x4.........

Surely 5.7 or 6 litres of Chev V8 would have at least as much torque down low as a 3.5 litre Rover V8. If not, it would just be a matter of correct cam selection to cure it.

Ok I know of 3 1uz-fe conversions. They all were in tojos.

1st one was into a 4runner, he cooked the 1st motor after having all sorts of teething problems. He replaced the motor as it was cheaper to get another motor than get new head gaskets, had a few more problems due to after market ecu, but is fairly good now.Still has heating issues here & there.

The 2nd one was into an sr5 hilux (3l diesel model) & after 6 months it still isnt on the road. He is using an after market ecu.

The 3rd was into a Bundera. He has fitted his with the standard ecu & with the info from the previous people has has no worries, in & out in 2 weeks & enjoying it.

The key appears to be to use a standard ecu, all though the power gains & control are much better with an after market ecu,, the problems are larger as well.

Hope this helped

They don't actually, mark2 is right. Mate of mine was Holden Qld state mgr, drove everything Holden made or badged, including a specced 4 door SS gen3 with hollinger. It was a real dissapointment, didn't come on song until close to 70k in 1st, clutch felt like an old HQ 1 tonner, and rode like a dray, nothing sporty about it, certainly not a car to punt thru the twisties in. However the fix to the engine's lacklustre low down torque is only a chip away as it's tuned to meet emmisions so is very soft in std form.

Hi all
This may be a dumb question but why not go for the rover 4.6 engine bolts straight in and no problems with egineering. I am only asking because I am thinking of doing this as my 3.9 is on it's last legs thanks to the previous owner not putting coolant in it and it is very corroded. I'm interested in all of your thoughts coz no matter what we do it is expensive.

Cheers Blythe

P.S. not intending to steal the link just curious

Didn't the 4.6 have issues with porous or slipping liners? I was under the impression that the 4.0 is a better motor.

How about a supercharger?

If any of you wouldbe engine swappers are interested in fitting a supercharged 3.9L complete with all looms,ECU and Davis piggyback ECU I could probably provide one
