Currently my scheduled mods stretch only too a Holden carby, and a 2 in free flow exhaust, we already have electronic ignition. What say the experts?

Leave the dinghy at home....

no no no, leave the missus at home and take the dinghy and the dog instead

If ya guna fit anything and want reliability go find a 4bd1 and lt95 and fit them to it and some s3stage 1 diffs

That can be a major operation though. Also, the Birdsville Tk is pretty good, and not one that I'd be too worried about power on.

I'd suggest it's time to start reading British Landrover magazines. Our British cousins have developed an upgrade for the 2.25 - a better cam, head work, electronic dizzy and (I think) some pipe work. You'll find it advertised every so often in the three major mags: LR world, LROI and LR Monthly. It should be easy to get just the cam posted to Australia- then custom pipework and some head flowing should be easy. Adding a turbo might be a little problematic with unleaded fuel, finding an intercooler and a turbo manifold to suit - then fitting the lot into the small engine bay of the series.

my 3 is a stage one, shes got the good diffs,shes an 82 model, she has the later motor with extra bearings on crank, never had a 2.25 in bits but they seem agricultural enuff for the bear to tackle.

Just do it. You know you want to.

The 2.25 came with a Turbo option in the later 5 main bearing motor. You could try fitting one to a 3 main bearing, I can't say how it would go. Your best option would be to get a turbo manifold from a 5 main bearing 2.5, probably out of the UK. Try getting a copy of LRO International and scour the pages for adverts of wreckers or engine modifiers that may have them. Make sure you get the JULY isuue and read about my trip EAST-WEST across the Simpson in a 2.25 Petrol SIII.
