Hi All
Hypothetically, if my 3 Litre died in Oz, what could I fit as a replacement?
The car is currently so far away from original due to previous owners tinkering a restomod would not be out of the question.
Land Rover / Range Rover?
Ford 6 / 8?
Holden (Buick) V6?
Japanese?

A neighbour has built a Briggs & Stratton V8 for his ride-on mower. I could ask if he'd make another if you like.

Not sure. I must ask. I haven't seen it.
He has just finished fitting a flat-head Ford V8 into an immaculate grey Fergy. Apparently they used to do that when they were new.

The original 215ci V8 that Rover purchased the tooling and build rights to is originally a GM engine dating back to the early 1960s. Considering this and that the Holden V6 is a direct descendent of that alloy V8, so why not fit a Commodore V6 efi and 4 speed automatic transmission. Lots of parts, compact engine trans package, very reliable, emissions clean, fuel efficient and an overdrive automatic. It doesn't get much better than that.

I'd seriously consider an option like that, modern, reliable and common as muck over here. Plenty on ebay, Motor and Trans for under $1k I'd have to upgrade the brakes and fit power steering as well which are on the cards anyway. |

All you'd have to do is fit a new set of P5B discs and calipers to the front end. The Rover 3 litre engine is heavier than the V6 and the V6 is only 300cc larger in capacity than a 3.5 Rover V8...so you'd fall well within the upgrade specs. The 4 speed overdrive would also work well with your current diff ratio (3.7:1 I believe) so you won't need to change that either...saving more money on the conversion. The final drive units are very tough and the axles look like they were made for a tank. If you want an OEM Rover power steering box I have a spare but not a spare pitman arm.  |

Thanks, I'll keep the steering box in mind. I want to finish the Mini now that I have this Club Plated, I can only fit one in the garage, roll on summer. |

And you could use a 700R auto from eg VP Commodore, so you'd not need a computer to run it. It uses a cable for pressure. A 3 litre in-line 6 from earlier Commodore may work too. Then you can use an RL4R01A from a diesel Laurel. That too uses only a cable for pressure. I've used them in my Rover and Daimler. Simple on/off switch for o/d, and lock/up cancel. (If desired.) Paul. NZ.

I have a spare pitman arm, if the time comes. I'm sure you'd blanch at the thought of dieseling your Rover....but. My one had no running gear at purchase, so I had few qualms about making a cheap daily driver by simply (ha) fitting a QD32 Nissan turbo intercooled diesel and RL4RO1A auto. Man does that thing move out. As long as I stay away from physically going to Rover clubs, I'm fine. See, it's considered almost acceptable to fit things like V6's, Chev V8's etc, but NOT diesels.
I'm old enough not to be too worried. I fitted a TD27 turbo I/C diesel and that RL4 auto to my '64 Daimler. Now 2.6:1 ratio, and a fantastic cruiser. 40 mpg, with more usable performance than that anaemic 2.5 V8. Paul. NZ.

Funny you should raise that, the previous owner had planned to do just that if the engine died. Apparently a lot of smashed utes around with perfect running gear. |

If you do look at s/t like a Nissan QD32 diesel, you'll need a manual g/box one, prior to fitting auto. I think they don't use the electronic diesel pump. Failing that, you'd need to have the pump converted to non-electronic. Or look at using the whole ute computer set-up. Early days I know. If gas was cheaper than almost $10/gallon, I'd Commodore 6 or V6 mine.

Hi, bit late on this thread - I have similar plans to install a super charged commodore motor into a P5 coupe which I purchased from a farmer in South Gippsland, still sitting in a barn at his place. Currently finishing off my 69 Coupe with Disco 3.9 SE motor, otherwise pretty standard. NZ I'd be interested to see some more pictures of your car. Wheels look interesting, did you have to make any changes in rear arches to fit them in? What other mods have you made?
