Thread: CAN YOU INCREASE BORE/STROKE ON THE PUMA FOR MORE GRUNT??

In theory it is possible, however I doubt there is a kit available. Many diesels run hardened liners so boring is not possible. That leaves stroking, for which you need a new crank, etc...

It would likely be easier and cheaper to fit a larger engine.

Get rid of that useless 2.2 litre paper weight and fit a 3.2 from a new Ranger/BT50.

If this is a silly question please forgive me as my knowledge of Deisel engines is still very limited compared to a petrol, but can you or has anybody increased the bore/stroke of their puma engines in the hunt for more power/torque?
If not what are the problems preventing this?

I have looked but found nothing on this.

You'd be surprised how much extra poke you can tweak out of the standard engine for limited cost. Mine is up around 50% in power (135kw) and around 25% in torque (470nm) - its much stronger to drive than the standard truck, despite significant weight increases.

By way of comparison, this is slightly less power and slightly more torque than the standard LC76 V8 motor.

Next step will either be a 3.2 Puma conversion or a Duramax - but that's 150,000 kms away at least.

Do what Land Rover should have done fifty years ago and put real engines in their cars. Minimum 5 litres.

and break your driveline piece by piece

if only the english taxing laws would have allowed it...

or you could do it and maintain one of the key requirements of the vehicle being fuel economy...

didnt toymota horse around with bigger engines and pay for it at the pump for not much better performance than what landrover got out of their smaller displacement engines.

there are medium trucks getting around with less displacement than that.

Land Rover paid for it in the market place, not at the pump. Get the cubic inches and do the job easy, and medium trucks with crappy little engines are a PIA to drive or to follow.

We were flogged in the Australian market place from late sixties on because the principal buyer group wanted to cruise easily at 60-70 mph. Cruisers and Patrols became the country vehicles of choice because they could.

Yes, that would be a great conversion, do you know anyone that has done it?
