Thread: advice needed

would the petrol be a better option? any advice would be appreciated

My 109D is flat out at about 80 to 90kmh. I have an overdrive, so can wind it up to 100kmh but not really comfortable at those speeds.

As long as your not in a hurry, it is a great motor.

It's noisey though.

Can't speak for the petrol - haven't owned one. (yet )

I have a 2.25 Petrol in my IIA, it has been rebuilt around 10 years ago with extractors and holden carby but is probably in an average state of tune at the moment after sitting unused for 5 years

Saying that she cruises great at 40mph and will get to 52mph however i think my speedo is not geared properly for the 7.50R16s so maybe even faster It is very slow and gutless arond town but it does eventually get to speed - don't like going up hills though

Low range makes up for everything I love being able to climb a tree in low first at idle

I have no overdrive by the way and haven't driven it on a highway yet so i am hoping to get to 55mph+

That toro ovedrive sounds good, I would get one to use it like a split diff on a truck for the novelty

To quote Jeremy from Top Gear, "right there's first, 1.5, second, 2.5, 3" whilst driving a semi on the truck challenge hahahaha

My first Landy was a 2.25 diesel. Yes, they are slow and noisy on the road, but once you turn off the bitumen they are where they are meant to be. Even just driving on a flat gravel road, they seem to go the perfect speed.

The petrol engine is certainly more driveable than the diesel, and also it is quite possible to get a worthwhile improvement in performance by mild tuning. (although note that most examples will benefit from being brought to standard spec - e.g. timing, ignition components in good shape, wear on distributor rectified, working thermostat, carbie in good shape, tyre pressure right etc)

My lwb unless heavily loaded will cruise, albeit a bit noisily, at 100kph, but will lose speed on any hill worthy of the name. But drop back to 90, not only a lot quieter, but also fuel economy is better. Drop back to 80, and you will keep the speed on most hills, and furthermore, you may even approach 14l/100km, compared to the more normal 18-20l/100km.

If I were you I'd leave the 250 in it. They are my next pick from a Hemi in a series. Fix the box and don't floor it in 1st at all,3rd for to long or reverse at all and the series box will take it. You can give them hell in 2nd and 4th all day. In the late 80s we ran a Tuboed 202 in a 109 this way and only smashed one box doing a flat change to 3rd trying to drag race an XU1
Still run series here now and if the box is treated right they are very durable.
Why would you want to go back to a Rover diesel They are a great pluger but not to much fun over long distance.

The 2.25 petrol will send you broke in fuel usage if driven hard. 80kmh +
The 250 ford will likely do around 25mpg if driven sensibly.

maybe i should just stay with the xflow?
