Thread: 4.4 in to rangie

Crankshaft-end PCD and diameter is bigger, engine is wider, EFI manifold needs spacer plates (available, I have a bookmark on the site somewhere) engine mounts need adapting and the block drilling for more bolts. This is not as straightforward as in the old days of 4 speed manuals, plus because of emissions laws you won't find it easy to get engineering approval. Get a 4.6, its a drop-in fit.

2 door 4.4 in newcastle for scrap prices last week on ebay.
if it has a B/W auto it is a straight bolt up.other wise you have to add a spacer/adaptor to the leyland driveplate.

front timing case,cam oil pump drive gears pulleys and extras should be swaped-these are balanced to the crank.

Ive got SD1 4 engine pipe headers on my P76 and to do this or other manifolds you need rover stater motor modifications.

the engine passes exhaust emision especially with delco efi
in other states of OZ an 88 isnt ULP and a 4.4 passes for ADR27's
My 89 hiline also isnt ULP so you need to check.

a 3.9 disco motor cost lot less than the fuel and rego mods and testing.dont kow how much a 4.6 conversion would cost.

I put a 4.4 in my old 88 Rangie. Big job.
There were kits on the market that covered many of the necessary mods, not so easy to obtain now I think. The kit I used included the following:
Rear crankshaft adapter, Spacers for the 3.5 inlet manifold, adapter ring for the RR starter motor (the RR starter motor is more robust than the Leyland one, but the nose of the starter has a different diameter).
Engine mount adapters I fabricated myself. Bell-housing bolts straight up. Brackets for the PS pump have to be extended 3/4". The standard 3.5 radiator will cool adequately, if towing a fully loaded camper from Gippsland to Broome is any test. Biggest problem I faced is that the EFI off the 3.5 will not supply enough fuel for the 4.4 under full load and the motor will run too lean. I fitted an aftermarket programmable EFI system to enable the injectors to get sufficient duty cycle.
Cost of this conversion is likely to far exceed the value of any 88 rangie out there.

The spacer plates will lift the plenum top to a point where it will hit the underside of the bonnet. The 4.4 also don't have the bolt fittings at the front of the RHS head that are used to mount the A/C compressor.

Using 3.5/3.9 extractors on the 4.4 also require modification to avoid hitting the chassis side rails.

Follow Bee utey's suggestion and fit a 4.6.
